However, little is known about how and to what extent the explainee takes part actively in the process of explaining. To tackle this empirical gap, we exploratively examined naturally occurring everyday explanations in doctor–patient interactions (<jats:italic>N</jats:italic> = 11). Following the social design of XAI, we view explanations as emerging in interactions: first, we identified the verbal behavior of both the explainer and the explainee in the sequential context, which we could assign to phases that were either monological or dialogical; second, we investigated in particular who was responsible for the initiation of the different phases. Finally, we took a closer look at the global conversational structure of explanations by applying a context-sensitive model of organizational jobs, thus adding a third layer of analysis. Results show that in our small sample of conversational explanations, both monological and dialogical phases varied in their length, timing of occurrence (at the early or later stages of the interaction) and their initiation (by the explainer or the explainee). They alternated several times in the course of the interaction. However, we also found some patterns suggesting that all interactions started with a monological phase initiated by the explainer. Both conversational partners contributed to the core organizational job that constitutes an explanation. We interpret the results as an indication for naturally occurring everyday explanations in doctor–patient interactions to be co-constructed on three levels of linguistic description: (1) by switching back and forth between monological to dialogical phases that (2) can be initiated by both partners and (3) by the mutual accomplishment and thus responsibility for an explanation’s core job that is crucial for the success of the explanation. Because of the explorative nature of our study, these results need to be investigated (a) with a larger sample and (b) in other contexts. However, our results suggest that future designs of artificial explainable systems should design the explanatory dialogue in such a way that it includes monological and dialogical phases that can be initiated not only by the explainer but also by the explainee, as both contribute to the core job of explicating procedural, clausal, or conceptual relations in explanations.</jats:p>"}],"date_created":"2024-02-14T09:44:23Z","department":[{"_id":"660"}],"keyword":["Artificial Intelligence"],"type":"journal_article","status":"public","publisher":"Springer Science and Business Media LLC","_id":"51349","page":"317-326","volume":36,"user_id":"57578","citation":{"ieee":"J.

We find three principal configurations of hole polarons: (i) self-trapped holes localized at displaced regular oxygen atoms and (ii) two other configurations bound to a lithium vacancy either at a threefold coordinated oxygen atom above or at a two-fold coordinated oxygen atom below the defect. The latter is the most stable and is in excellent quantitative agreement with measured g factors from electron paramagnetic resonance. Due to the absence of mid-gap states, none of these hole polarons can explain the broad optical absorption centered between 2.5 and 2.8 eV that is observed in transient absorption spectroscopy, but such states appear if a free electron polaron is trapped at the same lithium vacancy as the bound hole polaron, resulting in an exciton polaron. The dielectric function calculated by solving the Bethe–Salpeter equation indeed yields an optical peak at 2.6 eV in agreement with the two-photon experiments. The coexistence of hole and exciton polarons, which are simultaneously created in optical excitations, thus satisfactorily explains the reported experimental data.","lang":"eng"}],"issue":"11","publication":"Crystals"},{"intvolume":"       121","publication_status":"published","date_updated":"2025-12-05T13:50:49Z","publication_identifier":{"issn":["0003-6951","1077-3118"]},"author":[{"first_name":"Ying","last_name":"Gao","full_name":"Gao, Ying"},{"full_name":"Li, Yao","first_name":"Yao","last_name":"Li"},{"id":"59416","first_name":"Xuekai","last_name":"Ma","full_name":"Ma, Xuekai"},{"last_name":"Gao","first_name":"Meini","full_name":"Gao, Meini"},{"first_name":"Haitao","last_name":"Dai","full_name":"Dai, Haitao"},{"id":"27271","full_name":"Schumacher, Stefan","orcid":"0000-0003-4042-4951","first_name":"Stefan","last_name":"Schumacher"},{"full_name":"Gao, Tingge","first_name":"Tingge","last_name":"Gao"}],"year":"2022","title":"Tilting nondispersive bands in an empty microcavity","doi":"10.1063/5.0093908","language":[{"iso":"eng"}],"article_number":"201103","issue":"20","publication":"Applied Physics Letters","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"705"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"keyword":["Physics and Astronomy (miscellaneous)"],"type":"journal_article","date_created":"2022-11-16T12:29:11Z","status":"public","volume":121,"user_id":"16199","publisher":"AIP Publishing","_id":"34094","project":[{"name":"TRR 142: TRR 142","_id":"53"},{"_id":"54","name":"TRR 142 - A: TRR 142 - Project Area A"},{"name":"TRR 142 - A4: TRR 142 - Subproject A4","_id":"61"},{"_id":"53","name":"TRR 142: Maßgeschneiderte nichtlineare Photonik: Von grundlegenden Konzepten zu funktionellen Strukturen"}],"citation":{"ama":"Gao Y, Li Y, Ma X, et al.

In this study, a variety of electron polarons, namely free, bound, and bipolarons, are analyzed using first-principles calculations. We perform a full structural optimization based on density-functional theory for selected intrinsic defects with special attention to the role of symmetry-breaking distortions that lower the total energy. The cations hosting the various polarons relax to a different degree, with a larger relaxation corresponding to a larger gap between the defect level and the conduction-band edge. The projected density of states reveals that the polaron states are formerly empty Nb 4d states lowered into the band gap. Optical absorption spectra are derived within the independent-particle approximation, corrected by the GW approximation that yields a wider band gap and by including excitonic effects within the Bethe-Salpeter equation. Comparing the calculated spectra with the density of states, we find that the defect peak observed in the optical absorption stems from transitions between the defect level and a continuum of empty Nb 4d states. Signatures of polarons are further analyzed in the reflectivity and other experimentally measurable optical coefficients.","lang":"eng"}],"date_created":"2022-03-13T15:28:47Z","type":"book_chapter","department":[{"_id":"296"},{"_id":"230"},{"_id":"429"},{"_id":"295"},{"_id":"15"},{"_id":"170"},{"_id":"35"},{"_id":"790"}]},{"date_created":"2023-02-06T02:30:08Z","type":"conference","department":[{"_id":"623"},{"_id":"15"},{"_id":"429"},{"_id":"642"}],"citation":{"bibtex":"@article{Sartison_ Camacho Ibarra_Jöns_Caltzidis_Reuter_2022, series={Materials for Quantum Technology}, title={Scalable integration of quantum emitters into photonic integrated circuits}, volume={2}, DOI={<a href=\"https://doi.org/10.1088/2633-4356/ac6f3e\">https://doi.org/10.1088/2633-4356/ac6f3e</a>}, author={Sartison, M and  Camacho Ibarra, O and Jöns, Klaus D. and Caltzidis, I and Reuter, Dirk}, year={2022}, collection={Materials for Quantum Technology} }","chicago":"Sartison, M, O  Camacho Ibarra, Klaus D.

However, the material dispersion of integrated platforms constitutes an obstacle that limits the performance and precision of such interferometers. At the same time, two-colour nonlinear interferometers present an important tool for metrological applications, when measurements in a certain frequency range are difficult. In this manuscript, we theoretically developed and investigated an integrated multimode two-colour SU(1,1) interferometer operating in a supersensitive mode. By ensuring the proper design of the integrated platform, we suppressed the dispersion, thereby significantly increasing the visibility of the interference pattern. The use of a continuous wave pump laser provided the symmetry between the spectral shapes of the signal and idler photons concerning half the pump frequency, despite different photon colours. We demonstrate that such an interferometer overcomes the classical phase sensitivity limit for wide parametric gain ranges, when up to 3×104 photons are generated.</jats:p>","lang":"eng"}],"publication":"Symmetry","issue":"3","keyword":["Physics and Astronomy (miscellaneous)","General Mathematics","Chemistry (miscellaneous)","Computer Science (miscellaneous)"],"type":"journal_article","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"429"},{"_id":"230"},{"_id":"9"},{"_id":"27"}],"date_created":"2023-01-26T13:54:00Z","date_updated":"2025-12-16T11:27:11Z","publication_status":"published","intvolume":"        14","year":"2022","title":"Two-Colour Spectrally Multimode Integrated SU(1,1) Interferometer","publication_identifier":{"issn":["2073-8994"]},"author":[{"full_name":"Ferreri, Alessandro","last_name":"Ferreri","first_name":"Alessandro"},{"full_name":"Sharapova, Polina R.","last_name":"Sharapova","first_name":"Polina R.","id":"60286"}],"doi":"10.3390/sym14030552","article_number":"552","language":[{"iso":"eng"}]},{"citation":{"ama":"Ebers L, Ferreri A, Hammer M, et al.

To properly use these components in the implementation of different quantum protocols, photons with different properties are required. In this paper, we theoretically demonstrate a flexible source of correlated photons built on the LNOI waveguide of a special geometry. This source is based on the parametric down-conversion (PDC) process, in which the signal and idler photons are generated at the telecom wavelength and have different spatial profiles and polarizations, but the same group velocities. Distinguishability in polarizations and spatial profiles facilitates the routing and manipulating individual photons, while the equality of their group velocities leads to the absence of temporal walk-off between photons. We show how the spectral properties of the generated photons and the number of their frequency modes can be controlled depending on the pump characteristics and the waveguide length. Finally, we discuss special regimes, in which narrowband light with strong frequency correlations and polarization-entangled Bell states are generated at the telecom wavelength."}],"related_material":{"link":[{"relation":"erratum","url":"https://doi.org/10.1088/2515-7647/acc70c","description":"Corrigendum for table C1"}]},"language":[{"iso":"eng"}],"doi":"10.1088/2515-7647/ac5a5b","publication_identifier":{"issn":["2515-7647"]},"author":[{"id":"40428","last_name":"Ebers","first_name":"Lena","full_name":"Ebers, Lena"},{"full_name":"Ferreri, Alessandro","first_name":"Alessandro","last_name":"Ferreri","id":"65609"},{"id":"48077","full_name":"Hammer, Manfred","last_name":"Hammer","orcid":"0000-0002-6331-9348","first_name":"Manfred"},{"full_name":"Albert, Maximilian","first_name":"Maximilian","last_name":"Albert"},{"id":"20798","last_name":"Meier","first_name":"Cedrik","orcid":"https://orcid.org/0000-0002-3787-3572","full_name":"Meier, Cedrik"},{"id":"158","full_name":"Förstner, Jens","first_name":"Jens","last_name":"Förstner","orcid":"0000-0001-7059-9862"},{"id":"60286","full_name":"Sharapova, Polina R.","last_name":"Sharapova","first_name":"Polina R."}],"title":"Flexible source of correlated photons based on LNOI rib waveguides","year":"2022","intvolume":"         4","date_updated":"2025-12-16T11:31:04Z","publication_status":"published"},{"project":[{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"},{"name":"TRR 142: TRR 142","_id":"53"}],"citation":{"bibtex":"@article{Held_Engelkemeier_De_Barkhofen_Sperling_Silberhorn_2022, title={Driven Gaussian quantum walks}, volume={105}, DOI={<a href=\"https://doi.org/10.1103/physreva.105.042210\">10.1103/physreva.105.042210</a>}, number={4042210}, journal={Physical Review A}, publisher={American Physical Society (APS)}, author={Held, Philip and Engelkemeier, Melanie and De, Syamsundar and Barkhofen, Sonja and Sperling, Jan and Silberhorn, Christine}, year={2022} }","ama":"Held P, Engelkemeier M, De S, Barkhofen S, Sperling J, Silberhorn C.

In this contribution, the notion of a driven Gaussian quantum walk is introduced. In contrast to typically considered quantum walks in optical settings, we describe the operation of the walk in terms of a nonlinear map rather than a unitary operation, e.g., by replacing a beam-splitter-type coin with a two-mode squeezer, being a process that is controlled and driven by a pump field. This opens previously unattainable possibilities for quantum walks that include nonlinear elements as core components of their operation, vastly extending their range of applications. A full framework for driven Gaussian quantum walks is developed, including methods to dynamically characterize nonlinear, quantum, and quantum-nonlinear effects. Moreover, driven Gaussian quantum walks are compared with their classically interfering and linear counterparts, which are based on classical coherence of light rather than quantum superpositions. In particular, the generation and boost of highly multimode entanglement, squeezing, and other quantum effects are studied over the duration of the nonlinear walk. Importantly, we prove the quantumness of the evolution itself, regardless of the input state. A scheme for an experimental realization is proposed. Furthermore, nonlinear properties of driven Gaussian quantum walks are explored, such as amplification that leads to an ever increasing number of correlated quantum particles, constituting a source of new walkers during the walk. Therefore, a concept for quantum walks is proposed that leads to—and even produces—directly accessible quantum phenomena, and that renders the quantum simulation of nonlinear processes possible."}],"issue":"4","publication":"Physical Review A","department":[{"_id":"623"},{"_id":"15"},{"_id":"170"},{"_id":"706"},{"_id":"288"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"type":"journal_article","date_created":"2022-04-20T06:38:07Z","article_type":"original","intvolume":"       105","publication_status":"published","date_updated":"2026-01-09T09:50:22Z","author":[{"id":"68236","first_name":"Philip","last_name":"Held","full_name":"Held, Philip"},{"first_name":"Melanie","last_name":"Engelkemeier","full_name":"Engelkemeier, Melanie"},{"full_name":"De, Syamsundar","last_name":"De","first_name":"Syamsundar"},{"full_name":"Barkhofen, Sonja","last_name":"Barkhofen","first_name":"Sonja","id":"48188"},{"last_name":"Sperling","first_name":"Jan","orcid":"0000-0002-5844-3205","full_name":"Sperling, Jan","id":"75127"},{"id":"26263","last_name":"Silberhorn","first_name":"Christine","full_name":"Silberhorn, Christine"}],"publication_identifier":{"issn":["2469-9926","2469-9934"]},"title":"Driven Gaussian quantum walks","year":"2022","doi":"10.1103/physreva.105.042210","language":[{"iso":"eng"}],"article_number":"042210","main_file_link":[{"url":"https://journals.aps.org/pra/abstract/10.1103/PhysRevA.105.042210"}]},{"type":"conference","keyword":["Near-Field Scanning","Huygens Box","Boundary Element Method","Method of Moments","tet_topic_hf","tet_enas"],"department":[{"_id":"59"},{"_id":"61"},{"_id":"485"}],"date_created":"2022-10-04T11:31:43Z","abstract":[{"lang":"eng","text":"In this publication a novel method for far-field prediction from magnetic Huygens box data based on the boundary element method (BEM) is presented.
