Entangled systems with a large number of photons are of great interest at present because they provide a platform for streaming technologies based on photonics. In this paper we present a device which operates with four-photons and based on the Hong–Ou–Mandel interference. The presented device allows to maximize the degree of spatial entanglement and generate the highly entangled four-dimensional Bell states. Furthermore, the use of the interferometer in different regimes leads to fast interference fringes in the coincidence probability with period of oscillations twice smaller than the pump wavelength. We have a good agreement between theoretical simulations and experimental results.</jats:p>","lang":"eng"}],"publication":"Quantum Science and Technology","type":"journal_article","language":[{"iso":"eng"}],"keyword":["Electrical and Electronic Engineering","Physics and Astronomy (miscellaneous)","Materials Science (miscellaneous)","Atomic and Molecular Physics","and Optics"],"article_number":"045020","department":[{"_id":"15"},{"_id":"569"},{"_id":"170"},{"_id":"288"},{"_id":"230"},{"_id":"429"},{"_id":"35"}],"user_id":"16199","_id":"40381","project":[{"name":"TRR 142: TRR 142","_id":"53"},{"_id":"56","name":"TRR 142 - C: TRR 142 - Project Area C"},{"name":"TRR 142 - C2: TRR 142 - Subproject C2","_id":"72"}]},{"issue":"15","publication_status":"published","publication_identifier":{"issn":["2469-9950","2469-9969"]},"citation":{"apa":"Vondran, J., Spitzer, F., Bayer, M., Akimov, I.

Starting from the relaxed atomic geometries, we analyze the influence of self-energy corrections on the electronic band structure within the GW approximation. We find that quasiparticle shifts widen the direct (indirect) band gap by 1.21 (1.44), 1.58 (1.55), and 1.67 (1.64) eV for the cubic, tetragonal, and orthorhombic phase, respectively. By solving the Bethe-Salpeter equation, we obtain the linear dielectric function with excitonic and local-field effects, which turn out to be essential for good agreement with experimental data. From our results, we extract an exciton binding energy of 0.6, 0.5, and 0.5 eV for the cubic, tetragonal, and orthorhombic phase, respectively. Furthermore, we investigate the nonlinear second-harmonic generation (SHG) both theoretically and experimentally. The frequency-dependent second-order polarization tensor of orthorhombic KNbO3 is measured for incoming photon energies between 1.2 and 1.6 eV. In addition, calculations within the independent-(quasi)particle approximation are performed for the tetragonal and orthorhombic phase. The novel experimental data are in excellent agreement with the quasiparticle calculations and resolve persistent discrepancies between earlier experimental measurements and ab initio results reported in the literature."}],"file":[{"access_level":"open_access","file_name":"PhysRevMaterials.3.054401.pdf","file_id":"18465","description":"© 2019 American Physical Society","file_size":1949504,"title":"Quasiparticle and excitonic effects in the optical response of KNbO3","date_created":"2020-08-27T19:05:54Z","creator":"schindlm","date_updated":"2020-08-30T14:34:33Z","relation":"main_file","content_type":"application/pdf"}],"publication":"Physical Review Materials","doi":"10.1103/PhysRevMaterials.3.054401","oa":"1","date_updated":"2023-04-20T14:20:33Z","volume":3,"author":[{"id":"35251","full_name":"Schmidt, Falko","last_name":"Schmidt","orcid":"0000-0002-5071-5528","first_name":"Falko"},{"full_name":"Riefer, Arthur","last_name":"Riefer","first_name":"Arthur"},{"full_name":"Schmidt, Wolf Gero","id":"468","orcid":"0000-0002-2717-5076","last_name":"Schmidt","first_name":"Wolf Gero"},{"first_name":"Arno","last_name":"Schindlmayr","orcid":"0000-0002-4855-071X","full_name":"Schindlmayr, Arno","id":"458"},{"first_name":"Mirco","last_name":"Imlau","full_name":"Imlau, Mirco"},{"first_name":"Florian","last_name":"Dobener","full_name":"Dobener, Florian"},{"first_name":"Nils","full_name":"Mengel, Nils","last_name":"Mengel"},{"last_name":"Chatterjee","full_name":"Chatterjee, Sangam","first_name":"Sangam"},{"full_name":"Sanna, Simone","last_name":"Sanna","first_name":"Simone"}],"intvolume":"         3","citation":{"apa":"Schmidt, F., Riefer, A., Schmidt, W.

Within the independent-particle approximation an electronic transport gap of 2.97 eV is obtained that widens to about 5.23 eV when quasiparticle effects are included using the GW approximation. The optical response is shown to be strongly anisotropic due to (i) the slight asymmetry of the TiO6 octahedra in the (001) plane and (ii) their anisotropic distribution along the [001] and [100] directions. In addition, excitonic effects are very important: The solution of the Bethe–Salpeter equation indicates exciton binding energies of the order of 1.5 eV. Calculations that include both quasiparticle and excitonic effects are in good agreement with the measured reflectivity."}],"date_created":"2019-09-19T14:34:16Z","publisher":"IOP Publishing","title":"Potassium titanyl phosphate (KTP) quasiparticle energies and optical response","quality_controlled":"1","year":"2019","user_id":"171","department":[{"_id":"296"},{"_id":"295"},{"_id":"230"},{"_id":"429"},{"_id":"170"},{"_id":"35"}],"project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"_id":"53","name":"TRR 142"},{"name":"TRR 142 - Project Area B","_id":"55"},{"name":"TRR 142 - Subproject B4","_id":"69"},{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"_id":"13365","file_date_updated":"2020-08-30T14:29:27Z","isi":"1","article_type":"original","type":"journal_article","status":"public","author":[{"id":"23261","full_name":"Neufeld, Sergej","last_name":"Neufeld","first_name":"Sergej"},{"last_name":"Bocchini","orcid":"https://orcid.org/0000-0002-2134-3075","id":"58349","full_name":"Bocchini, Adriana","first_name":"Adriana"},{"first_name":"Uwe","full_name":"Gerstmann, Uwe","id":"171","orcid":"0000-0002-4476-223X","last_name":"Gerstmann"},{"orcid":"0000-0002-4855-071X","last_name":"Schindlmayr","full_name":"Schindlmayr, Arno","id":"458","first_name":"Arno"},{"last_name":"Schmidt","orcid":"0000-0002-2717-5076","id":"468","full_name":"Schmidt, Wolf Gero","first_name":"Wolf Gero"}],"volume":2,"date_updated":"2023-04-21T11:36:12Z","oa":"1","doi":"10.1088/2515-7639/ab29ba","publication_status":"published","has_accepted_license":"1","publication_identifier":{"eissn":["2515-7639"]},"citation":{"chicago":"Neufeld, Sergej, Adriana Bocchini, Uwe Gerstmann, Arno Schindlmayr, and Wolf Gero Schmidt. “Potassium Titanyl Phosphate (KTP) Quasiparticle Energies and Optical Response.” <i>Journal of Physics: Materials</i> 2 (2019): 045003. <a href=\"https://doi.org/10.1088/2515-7639/ab29ba\">https://doi.org/10.1088/2515-7639/ab29ba</a>.","ieee":"S.

An aspect of particular interest is the active\r\ncontrol of such patterns. In nonlinear optical systems this can be used for\r\nall-optical switching with transistor-like performance, for example realized\r\nwith polaritons in a planar quantum-well semiconductor microcavity. Here we\r\nfocus on a specific configuration which takes advantage of the intricate\r\npolarization dependencies in the interacting optically driven polariton system.\r\nBesides detailed numerical simulations of the coupled light-field exciton\r\ndynamics, in the present paper we focus on the derivation of a simplified\r\npopulation competition model giving detailed insight into the underlying\r\nmechanisms from a nonlinear dynamical systems perspective. We show that such a\r\nmodel takes the form of a generalized Lotka-Volterra system for two competing\r\npopulations explicitly including a source term that enables external control.\r\nWe present a comprehensive analysis both of the existence and stability of\r\nstationary states in the parameter space spanned by spatial anisotropy and\r\nexternal control strength. We also construct phase boundaries in non-trivial\r\nregions and characterize emerging bifurcations. The population competition\r\nmodel reproduces all key features of the switching observed in full numerical\r\nsimulations of the rather complex semiconductor system and at the same time is\r\nsimple enough for a fully analytical understanding of the system dynamics."}],"user_id":"16199","department":[{"_id":"15"},{"_id":"170"},{"_id":"297"},{"_id":"230"},{"_id":"35"},{"_id":"27"}],"project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"13340","language":[{"iso":"eng"}],"citation":{"ama":"Pukrop M, Schumacher S.
