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.</jats:p>","lang":"eng"}],"volume":2,"date_created":"2026-01-12T13:18:51Z","author":[{"last_name":"Kopylov","id":"98502","full_name":"Kopylov, Denis","first_name":"Denis"},{"first_name":"Torsten","last_name":"Meier","orcid":"0000-0001-8864-2072","id":"344","full_name":"Meier, Torsten"},{"last_name":"Sharapova","id":"60286","full_name":"Sharapova, Polina R.","first_name":"Polina R."}],"date_updated":"2026-01-12T13:23:36Z","publisher":"AIP Publishing","doi":"10.1063/5.0293116","title":"Bipartite entanglement extracted from multimode squeezed light generated in lossy waveguides","issue":"4","publication_identifier":{"issn":["2835-0103"]},"publication_status":"published","intvolume":"         2","citation":{"ama":"Kopylov D, Meier T, Sharapova PR.

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."}],"file":[{"date_created":"2024-04-04T09:24:22Z","creator":"schindlm","date_updated":"2024-04-04T09:24:22Z","file_name":"Meyer_2024_J._Phys._B _At._Mol._Opt._Phys._57_095001.pdf","access_level":"open_access","file_id":"53204","file_size":358155,"description":"Creative Commons Attribution 4.0 International Public License (CC BY 4.0)","title":"Derivation of Miller's rule for the nonlinear optical susceptibility of a quantum anharmonic oscillator","content_type":"application/pdf","relation":"main_file"}],"external_id":{"isi":["001196678300001"]},"ddc":["530"],"language":[{"iso":"eng"}]},{"publication_identifier":{"issn":["2296-424X"]},"quality_controlled":"1","year":"2024","intvolume":"        12","citation":{"ama":"Schwind B, Wu X, Tiemann M, Fabritius H-O.

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.</jats:p>","lang":"eng"}],"publication":"Optics Express","type":"journal_article","doi":"10.1364/oe.521207","title":"Sub-cycle strong-field tunneling dynamics in solids","volume":32,"date_created":"2024-07-15T09:25:30Z","author":[{"last_name":"Yang","full_name":"Yang, Shidong","first_name":"Shidong"},{"first_name":"Xiwang","last_name":"Liu","full_name":"Liu, Xiwang"},{"full_name":"Zhang, Hongdan","last_name":"Zhang","first_name":"Hongdan"},{"first_name":"Xiaohong","full_name":"Song, Xiaohong","last_name":"Song"},{"full_name":"Zuo, Ruixin","last_name":"Zuo","first_name":"Ruixin"},{"last_name":"Meier","orcid":"0000-0001-8864-2072","id":"344","full_name":"Meier, Torsten","first_name":"Torsten"},{"last_name":"Yang","full_name":"Yang, Weifeng","first_name":"Weifeng"}],"publisher":"Optica Publishing Group","date_updated":"2024-07-15T09:29:23Z","intvolume":"        32","citation":{"ama":"Yang S, Liu X, Zhang H, et al.

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.

Mixed crystals with arbitrary Nb–Ta ratios provide an additional degree of freedom to not only tune materials properties, such as the birefringence but also leverage the advantages of the singular compounds, for example, by combining the thermal stability of lithium tantalate with the larger nonlinear or piezoelectric constants of lithium niobate. Periodic poling allows to achieve phase-matching independent of waveguide geometry and is, therefore, one of the commonly used methods in integrated nonlinear optics. For mixed crystals, periodic poling has been challenging so far due to the lack of homogeneous, mono-domain crystals, which severely inhibit domain growth and nucleation. In this work, we investigate surface-near (&amp;lt;1μm depth) domain inversion on x-cut lithium niobate tantalate mixed crystals via electric field poling and lithographically structured electrodes. We find that naturally occurring head-to-head or tail-to-tail domain walls in the as-grown crystal inhibit domain inversion at a larger scale. However, periodic poling is possible if the gap size between the poling electrodes is of the same order of magnitude or smaller than the average size of naturally occurring domains.

In addition, the electro-optic switching voltage is considerably increased when a polymer network is formed by in situ polymerization in the nematic state. However, the resulting polymer network liquid crystal switches at similar voltages as the neat liquid crystal when polymerization is performed at an elevated temperature in the isotropic state. When nanoparticle dispersions are polymerized at an applied DC voltage, the transition temperatures and switching voltages are reduced, yet they are larger than those observed for polymer network liquid crystals without nanoparticles polymerized in the isotropic phase.</jats:p>","lang":"eng"}],"type":"journal_article","publication":"Nanomaterials","language":[{"iso":"eng"}],"article_number":"961","user_id":"254","department":[{"_id":"313"},{"_id":"230"},{"_id":"2"}],"_id":"57618"},{"doi":"10.1021/acsaelm.3c01586","title":"Influence of the Deposition Rate on the Alignment and Performance of Perylene-3,4,9,10-tetracarboxylic Tetraethyl Ester in an Organic Light Emitting Diode","date_created":"2024-12-08T14:30:14Z","author":[{"first_name":"David","full_name":"Becker, David","last_name":"Becker"},{"full_name":"Meier, Patrick","last_name":"Meier","first_name":"Patrick"},{"full_name":"Kuhlmann, Andreas","last_name":"Kuhlmann","first_name":"Andreas"},{"full_name":"Sternemann, Christian","last_name":"Sternemann","first_name":"Christian"},{"full_name":"Bock, Harald","last_name":"Bock","first_name":"Harald"},{"first_name":"Hans-Georg","last_name":"Steinrück","orcid":"0000-0001-6373-0877","id":"84268","full_name":"Steinrück, Hans-Georg"},{"full_name":"Kitzerow, Heinz-Siegfried","id":"254","last_name":"Kitzerow","first_name":"Heinz-Siegfried"}],"volume":6,"publisher":"American Chemical Society (ACS)","date_updated":"2024-12-08T14:43:50Z","citation":{"apa":"Becker, D., Meier, P., Kuhlmann, A., Sternemann, C., Bock, H., Steinrück, H.-G., &#38; Kitzerow, H.-S.
