Two-terminal transport in biased lattices: transition from ballistic to diffusive current
Andrey R. Kolovsky
We analyze quantum transport of charged fermionic particles in the tight-binding lattice connecting two particle reservoirs (the leads). If the lead chemical potentials are differe…
Generalization of the Landauer-Büttiker theory onto the case of dissipative contacts
Andrey R. Kolovsky
We revisit the problem of two-terminal transport of non-interacting Fermi particles in a mesoscopic device. First, we generalize the problem by including into consideration relaxat…
Effects of internal and external decoherence on the resonant transport and Anderson localization of fermionic particles in the tight-binding chain
Andrey R. Kolovsky
We study effects of relaxation/decoherence processes on quantum transport of non-interacting Fermi particles across the tight-binding chain, where we distinguish between relaxation…
Topological flat Wannier-Stark bands
Andrey R. Kolovsky, Ajith Ramachandran, Sergej Flach
We analyze the spectrum and eigenstates of a quantum particle in a bipartite two-dimensional tight-binding dice network with short range hopping under the action of a dc bias. We f…
