Localized polarons and doorway vibrons in finite quantum structures
H. Fehske, G. Wellein, J. Loos +1
We consider transport through finite quantum systems such as quantum barriers, wells, dots or junctions, coupled to local vibrational modes in the quantal regime. As a generic mode…
Chebyshev approach to quantum systems coupled to a bath
Andreas Alvermann, Holger Fehske
We propose a new concept for the dynamics of a quantum bath, the Chebyshev space, and a new method based on this concept, the Chebyshev space method. The Chebyshev space is an abst…
Lattice exciton-polaron problem by quantum Monte Carlo simulations
Martin Hohenadler, Peter B. Littlewood, Holger Fehske
Exciton-polaron formation in one-dimensional lattice models with short or long-range carrier-phonon interaction is studied by quantum Monte Carlo simulations. Depending on the rela…
Particle-based modeling of oxygen discharges
F. X. Bronold, K. Matyash, David Tskhakaya +2
We present an one-dimensional particle-in-cell Monte-Carlo model for capacitively coupled radio-frequency discharges in oxygen. The model quantitatively describes the central part…
Correlation effects in partially ionized mass asymmetric electron-hole plasmas
V. S. Filinov, H. Fehske, M. Bonitz +2
The effects of strong Coulomb correlations in dense three-dimensional electron-hole plasmas are studied by means of unbiased direct path integral Monte Carlo simulations. The forma…
