In this work, we theoretically study two-mode bipartite states, which are extracted from multimode light generated via type-II parametric downconversion (PDC) in lossy waveguides. For these states, we demonstrate that the squeezing quantifies entanglement and we construct a measurement basis, which results in the maximal bipartite entanglement. We illustrate our findings by numerically solving the spatial master equation for PDC in a Markovian environment. The optimal measurement modes are compared with two widely used broadband bases: the Mercer–Wolf basis (the first-order coherence basis) and the Williamson–Euler basis.' article_number: '046116' author: - first_name: Denis full_name: Kopylov, Denis id: '98502' last_name: Kopylov - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Polina R. full_name: Sharapova, Polina R. id: '60286' last_name: Sharapova citation: ama: Kopylov D, Meier T, Sharapova PR.

The chemical and electronic properties of AlInP (001) depend on its surface reconstruction, which impacts its interaction with electrolytes in PEC applications and passivation layers. This study investigates AlInP (001) surface reconstructions using density functional theory and experimental methods. Phosphorus‐rich (P‐rich) and indium‐rich (In‐rich) AlInP surfaces are prepared with in situ monitoring of the process by reflection anisotropy (RA) spectroscopy and confirmed by low‐energy electron diffraction and photoemission spectroscopy. The experimental RA spectra closely match the theoretical predictions obtained by solving the Bethe–Salpeter equation. It is shown that missing hydrogen on P‐rich surfaces and formation of In–In 1D atomic chains on In‐rich surfaces introduce mid‐gap surface states that pin the Fermi level and induce band bending. Time‐resolved two‐photon photoemission measurements reveal ultrafast near‐surface electron dynamics for both P‐rich and In‐rich surfaces, demonstrating photoexcited electrons reaching the surface conduction band minimum and relaxing to mid‐gap surface states on about hundreds of fs. This work provides the most extensive AlInP surface analysis to date, allowing for more targeted surface and interface engineering, which is crucial for the optimization and design of III‐V heterostructures. author: - first_name: Mohammad Amin full_name: Zare Pour, Mohammad Amin last_name: Zare Pour - first_name: Sahar full_name: Shekarabi, Sahar last_name: Shekarabi - first_name: Isaac Azahel full_name: Ruiz Alvarado, Isaac Azahel id: '79462' last_name: Ruiz Alvarado orcid: 0000-0002-4710-1170 - first_name: Jonathan full_name: Diederich, Jonathan last_name: Diederich - first_name: Yuyings full_name: Gao, Yuyings last_name: Gao - first_name: Agnieszka full_name: Paszuk, Agnieszka last_name: Paszuk - first_name: Dominik C. full_name: Moritz, Dominik C. last_name: Moritz - first_name: Wolfram full_name: Jaegermann, Wolfram last_name: Jaegermann - first_name: Dennis full_name: Friedrich, Dennis last_name: Friedrich - first_name: Roel full_name: van de Krol, Roel last_name: van de Krol - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 - first_name: Thomas full_name: Hannappel, Thomas last_name: Hannappel citation: ama: 'Zare Pour MA, Shekarabi S, Ruiz Alvarado IA, et al.

Their usefulness for the generation of such nonclassical states of light is determined by orbital and spin decoherence mechanisms, particularly phonon-mediated processes dominant at energy scales up to a few millielectronvolts. Here, we directly measure the spectral function of orbital phonon relaxation between the energy states of the neutral exciton in a QDM and benchmark our findings against microscopic\r\n \r\n \r\n \ k\r\n ·\r\n \ p\r\n \r\n \r\n \r\n \ theory. Our results reveal pronounced resonances and antiresonances in the phonon-relaxation rates, ranging from tens of\r\n \r\n \r\n \ µ\r\n \r\n \ \r\n s\r\n \ \r\n \r\n \ −\r\n 1\r\n \ \r\n \r\n \r\n \ \r\n up to tens of\r\n \r\n \r\n \ \r\n ns\r\n \ \r\n \r\n −\r\n \ 1\r\n \r\n \ \r\n \r\n . Comparison with a kinetic model reveals the voltage (energy) dependent phonon coupling strength and fully explains the interplay between phonon-assisted relaxation and radiative recombination. The resonances and antiresonances enable further tunability of the exciton lifetime which can be leveraged to increase the lifetime of energetically unfavorable charge configurations needed for realizing efficient spin-photon interfaces and multidimensional cluster states.\r\n " article_number: '235305' author: - first_name: Michelle full_name: Lienhart, Michelle last_name: Lienhart - first_name: Krzysztof full_name: Gawarecki, Krzysztof last_name: Gawarecki - first_name: Markus full_name: Stöcker, Markus last_name: Stöcker - first_name: Frederik full_name: Bopp, Frederik last_name: Bopp - first_name: Charlotte full_name: Cullip, Charlotte last_name: Cullip - first_name: Nadeem full_name: Akhlaq, Nadeem last_name: Akhlaq - first_name: Christopher full_name: Thalacker, Christopher last_name: Thalacker - first_name: Johannes full_name: Schall, Johannes last_name: Schall - first_name: Sven full_name: Rodt, Sven last_name: Rodt - first_name: Arne full_name: Ludwig, Arne last_name: Ludwig - first_name: Dirk full_name: Reuter, Dirk id: '37763' last_name: Reuter - first_name: Stephan full_name: Reitzenstein, Stephan last_name: Reitzenstein - first_name: Kai full_name: Müller, Kai last_name: Müller - first_name: Paweł full_name: Machnikowski, Paweł last_name: Machnikowski - first_name: Jonathan J. full_name: Finley, Jonathan J. last_name: Finley citation: ama: Lienhart M, Gawarecki K, Stöcker M, et al.

While well established in GaAs/AlxGa1−xAs, this approach does not yield emission in the telecom bands required for low loss fiber-based quantum communication. To achieve emission at 1.55 μm, local droplet etching must be adapted to alternative material platforms such as InP. Here, we systematically investigate how the etching material deposition rate and etching time influence nanohole morphology in In0.52Al0.48As layers lattice-matched to InP. In the first experiment, InAl was deposited at fluxes of 0.2–4.0 Å s−1 at Tetch = 350 °C and 460 °C. Lower fluxes produced nanoholes with lower density and larger ring diameters, indicating fewer and larger initial droplets, consistent with scaling theory. The average nanohole diameter decreased monotonically with increasing flux, whereas the average depth showed no clear dependence on flux. In the second experiment, etching times of 30–600 s were tested for InAl, In, and Al droplets. Average nanohole diameters remained constant for Al across all etching times, but decreased for In and InAl with increasing etching time, suggesting sidewall redeposition during etching. For all droplet types, depths peaked at intermediate times and decreased for prolonged etching, consistent with material diffusion into the nanohole after droplet consumption. article_number: '913' author: - first_name: Dennis full_name: Deutsch, Dennis id: '23489' last_name: Deutsch - first_name: Dirk full_name: Reuter, Dirk id: '37763' last_name: Reuter citation: ama: Deutsch D, Reuter D.

In this work, we extend the proof and present a detailed derivation of Miller's rule for an equivalent quantum-mechanical anharmonic oscillator. For this purpose, the classical concept of velocity-dependent damping inherent to the Lorentz model is replaced by an adiabatic switch-on of the external electric field, which allows a unified treatment of the classical and quantum-mechanical systems using identical potentials and fields. Although the dynamics of the resulting charge oscillations, and hence the induced polarizations, deviate due to the finite zero-point motion in the quantum-mechanical framework, we find that Miller's rule is nevertheless identical in both cases up to terms of first order in the anharmonicity. With a view to practical applications, especially in the context of ab initio calculations for the optical response where adiabatically switched-on fields are widely assumed, we demonstrate that a correct treatment of finite broadening parameters is essential to avoid spurious errors that may falsely suggest a violation of Miller's rule, and we illustrate this point by means of a numerical example. article_number: '095001' article_type: original author: - first_name: Maximilian Tim full_name: Meyer, Maximilian Tim id: '77895' last_name: Meyer orcid: 0009-0003-4899-0920 - first_name: Arno full_name: Schindlmayr, Arno id: '458' last_name: Schindlmayr orcid: 0000-0002-4855-071X citation: ama: 'Meyer MT, Schindlmayr A.

This is remarkable, as the setae are also an adaption to enhance the reflectivity in the visible wavelength range. Both effects are dependent on morphology, dimensions and spatial arrangement. These parameters were experimentally characterized and simulated by finite difference time domain simulations to elucidate the optical impact of the setae in the mid infrared range and the contribution of leaky mode resonances.

However, the tunneling dynamics in solids, especially nonadiabatic tunneling, has not yet been fully understood. Here, we study the sub-cycle resolved strong-field tunneling dynamics in solids via a complex saddle-point method. We compare the instantaneous momentum at the moment of tunneling and the tunneling distances over a range of Keldysh parameters. Our results demonstrate that for nonadiabatic tunneling, tunneling ionization away from Γ point is possible. When this happens the electron has a nonzero initial velocity when it emerges in the conduction band. Moreover, consistent with atomic tunneling, a reduced tunneling distance as compared to the quasi-static case is found. Our results provide remarkable insight into the basic physics governing the sub-cycle electron tunneling dynamics with significant implications for understanding subsequent strong-field nonlinear phenomena in solids. article_number: '15862' author: - first_name: Shidong full_name: Yang, Shidong last_name: Yang - first_name: Xiwang full_name: Liu, Xiwang last_name: Liu - first_name: Hongdan full_name: Zhang, Hongdan last_name: Zhang - first_name: Xiaohong full_name: Song, Xiaohong last_name: Song - first_name: Ruixin full_name: Zuo, Ruixin last_name: Zuo - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Weifeng full_name: Yang, Weifeng last_name: Yang citation: ama: Yang S, Liu X, Zhang H, et al.

We show how the degree of impenetrability of dielectric inclusions plays a substantial role in controlling the coercive field, remnant and saturation polarizations of the homogenized materials. The results highlight the significance of the degree of impenetrability of inclusion in tuning the effective polarization properties of such ferroelectric composites: coercive field drops significantly as percolation threshold is attained and remnant polarization decreases faster than a linear decay.' author: - first_name: Viktor full_name: Myroshnychenko, Viktor id: '46371' last_name: Myroshnychenko - first_name: Pious Mathews full_name: Mulavarickal Jose, Pious Mathews last_name: Mulavarickal Jose - first_name: Henna full_name: Farheen, Henna id: '53444' last_name: Farheen orcid: 0000-0001-7730-3489 - first_name: Shafaq full_name: Ejaz, Shafaq last_name: Ejaz - first_name: Christian full_name: Brosseau, Christian last_name: Brosseau - first_name: Jens full_name: Förstner, Jens id: '158' last_name: Förstner orcid: 0000-0001-7059-9862 citation: ama: 'Myroshnychenko V, Mulavarickal Jose PM, Farheen H, Ejaz S, Brosseau C, Förstner J.

We outline and implement a largely analytic procedure forrigorous modal analysis of three-layer slabs with birefringent, anisotropic core. For Z-cut wave-guides, the slab eigenmode problem separates into uncoupled sets of scalar equations for TE andTM modes. Slabs in X-cut configuration support mostly mildly hybrid eigenmodes, with clear pre-dominant TE or TM polarization, and with effective indices that depend on the propagation directionof the modes, relative to the crystal axes. Strong hybridization can be observed for near degeneratemodes in singular configurations without vertical symmetry, or in symmetric slabs where two nearlydegenerate modes are of the same symmetry class. Dispersion curves for slab thickness and propa-gation angle are discussed, for slabs with oxide and air cover.
