Chaotic Dynamics and Quantum Transport
Andrey R. Kolovsky
This chapter gives an overview of transport problems where chaotic dynamics of the system plays a crucial role. We begin with single-particle transport problems and then come to co…
Analysis of self-thermalization dynamics in the Bose-Hubbard model by using the pseudoclassical approach
Andrey R. Kolovsky
We analyze the self-thermalization dynamics of the -site Bose-Hubbard model in terms of the single-particle density matrix that is calculated by using the pseudoclassical approa…
Sensing decoherence by using edge state
Andrey R. Kolovsky
In the absence of decoherence the current of fermionic particles across a finite lattice connecting two reservoirs (leads) with different chemical potentials is known to be ballist…
Dissipative chaos and steady state of open Tavis-Cummings dimer
Debabrata Mondal, Andrey Kolovsky, S. Sinha
We consider a coupled atom-photon system described by the Tavis-Cummings dimer (two coupled cavities) in the presence of photon loss and atomic pumping, to investigate the quantum…
Extraordinary resonant transmission in two-terminal fermionic transport
P. S. Muraev, D. N. Maksimov, A. R. Kolovsky
We analyze conductance of a two-leg ladder connected with fermionic reservoirs, focusing on the decoherence effect induced by the reservoirs. In the absence of decoherence the syst…
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…
