Quantum transport in an environment parametrized by dispersive bosons
Monodeep Chakraborty, Holger Fehske
We generalize the two-channel (Edwards) fermion-boson model describing quantum transport in a background medium to the more realistic case of dispersive bosons. Using the variation…
Particularities of polaron formation in the extended Holstein model with next nearest neighbor transfer
Monodeep Chakraborty, Jayita Chatterjee, Holger Fehske
Employing a largely unbiased variational exact diagonalization technique, we analyze the consequences of longer-ranged electron hopping and electron-phonon interaction on polaron f…
Electron microphysics at plasma-solid interfaces
F. X. Bronold, K. Rasek, H. Fehske
The most fundamental response of a solid to a plasma and vice versa is electric. An electric double layer forms with a solid-bound electron-rich region-the wall charge-and a plasma…
Kinetic modeling of the electric double layer at a dielectric plasma-solid interface
K. Rasek, F. X. Bronold, H. Fehske
For a collisionless plasma in contact with a dielectric surface, where with unit probability electrons and ions are, respectively, absorbed and neutralized, thereby injecting elect…
Driving XXZ spin chains: Magnetic-field and boundary effects
Florian Lange, Satoshi Ejima, Holger Fehske
Using the time-evolving block decimation, we study the spin transport through spin-1/2 and spin-1 XXZ chains subjected to an external magnetic field and contacted to noninteracting…
Exciton mass and exciton spectrum in the cuprous oxide
Andreas Alvermann, Holger Fehske
Excitons with a radius of a few lattice constants can be affected by strong central-cell corrections, leading to significant deviations of the optical spectrum from the hydrogen-li…
