The Fourier transform of the product of matrix elements of the dynamic propagators obeys an integral Wigner-Liouville-type equation. Initial conditions for this equation are given by the Fourier transform of the Wiener path-integral representation of the matrix elements of the propagators at the chosen initial times. This approach combines both molecular dynamics and Monte Carlo methods and computes numerical traces and spectra of the relevant dynamical quantities such as momentum-momentum correlation functions and spatial dispersions. Considering, as an application, a system with fixed scatterers, the results clearly demonstrate that the many-particle interaction between the electrons leads to an enhancement of the conductivity and spatial dispersion compared to the noninteracting case."}],"publication":"Physical Review B","issue":"16","department":[{"_id":"293"}],"type":"journal_article","date_created":"2023-04-02T13:23:14Z"},{"issue":"1-4","publication":"Physica B: Condensed Matter","abstract":[{"lang":"eng","text":"The influence of coherent photoexcited excitons on the absorption spectra and the Four Wave Mixing response of ZnSe/ZnMgSSe quantum wells is investigated for various polarization configurations.

For systems that are excited by two specially designed ultrashort light-pulse sequences delayed by \r\nτ\r\n relatively to each other echolike phenomena are predicted to occur. In addition to the interband photon echo which shows up at exactly t=2τ relative to the first pulse, the system responds with two spontaneous intraband current pulses preceding and following the appearance of the photon echo. The temporal splitting depends on the electron-hole mass ratio. Calculating the population relaxation rate due to Coulomb scattering, it is concluded that the predicted new dynamical effect should be experimentally observable in an interacting and strongly disordered system, such as the Quantum Coulomb Glass."}],"extern":"1","issue":"8","publication":"Physical Review B","department":[{"_id":"293"}],"type":"journal_article","date_created":"2023-04-02T13:14:09Z","status":"public","volume":65,"user_id":"49063","publisher":"American Physical Society","_id":"43291","citation":{"bibtex":"@article{Meier_Schlichenmaier_Varga_Thomas_Koch_2002, title={Optically induced coherent intraband dynamics in disordered semiconductors}, volume={65}, DOI={<a href=\"https://doi.org/10.1103/PhysRevB.65.085306\">10.1103/PhysRevB.65.085306</a>}, number={8085306}, journal={Physical Review B}, publisher={American Physical Society}, author={Meier, Torsten and Schlichenmaier, C. and Varga, I. and Thomas, P. and Koch, S.W.}, year={2002} }","ama":"Meier T, Schlichenmaier C, Varga I, Thomas P, Koch SW.

The near band-gap semiconductor response is determined by the optical interaction with the resonant or near resonant material polarization that may result in the excitation of carriers (electron–hole pairs) and/or transient coherent nonlinearities. The microscopic analysis of these effects requires the investigation of the relevant quasi-particles and their interactions. Whereas the basic occurrence of a blue shift can be motivated already based on a simple two-level model, a more detailed understanding of the optical Stark effect in semiconductors requires a microscopic modeling of the relevant bands as well as the inclusion of the many-body Coulomb interaction. Compensations among the first- and higher-order Coulomb terms at the spectral positions of the exciton are obtained in the differential absorption induced by incoherent occupations.","lang":"eng"}],"publication":"Ultrafast Physical Processes in Semiconductors"},{"intvolume":"        18","publication_status":"published","date_updated":"2023-04-02T14:18:37Z","author":[{"id":"344","first_name":"Torsten","orcid":"0000-0001-8864-2072","last_name":"Meier","full_name":"Meier, Torsten"},{"last_name":"Langbein","first_name":"W.","full_name":"Langbein, W."},{"last_name":"Koch","first_name":"S.W.","full_name":"Koch, S.W."},{"first_name":"J.M.","last_name":"Hvam","full_name":"Hvam, J.M."}],"title":"Spectral signatures of χ(5) processes in four-wave mixing of homogeneously broadened excitons","year":"2001","doi":"10.1364/JOSAB.18.001318","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://opg.optica.org/josab/abstract.cfm?uri=JOSAB-18-9-1318"}],"extern":"1","abstract":[{"text":"The influence of fifth-order coherences on the spectrally resolved four-wave mixing response of predominantly homogeneously broadened quasi-two-dimensional excitons is studied. Fifth-order signatures are discussed as a function of spectral position and excitation polarization. An exciton–biexciton beating for positive delay times is the dominant effect, which is pronounced at the exciton–biexciton transition for collinearly polarized excitation and at the exciton transition for cross-linearly polarized excitation. For negative delay times and collinearly polarized excitation a pronounced exciton–biexciton beating at the exciton resonance is observed that is vanishing for long negative delays owing to the faster dephasing in the two-exciton continuum compared with the bound biexciton state. These results are in qualitative agreement with microscopic model calculations that include the coherent dynamics of one- and two-exciton resonances up to the fifth order in the optical field.","lang":"eng"}],"publication":"Journal of the Optical Society of America B","issue":"9","department":[{"_id":"293"}],"type":"journal_article","date_created":"2023-04-02T14:18:34Z","status":"public","volume":18,"user_id":"49063","publisher":"Optical Society of America","_id":"43307","page":"1318-1325","citation":{"ama":"Meier T, Langbein W, Koch SW, Hvam JM.
