Abstract We describe an analytical theory investigating the regime of validity of the Fermi liquid theory in interacting, via the long-range Coulomb coupling, two-dimensional Fermi systems comparing… Expand

Spin switching: From quantum to quasiclassical approach

- Physics

In this paper, we review the theory of spin switching for systems of different sizes, from a quantum mechanical master equation approach for small atomic clusters to the quasiclassical description of… Expand

Bosonic superfluid transport in a quantum point contact

- Physics
- 2020

We present a microscopic theory of heat and particle transport of an interacting, low temperature Bose-Einstein condensate in a quantum point contact. We show that, in contrast to charged, fermionic… Expand

Coherent phonon dynamics of normal metal in ultrafast spectroscopy: Non-equilibrium gauge invariant Green's function approach

- Physics
- 2016

Abstract The phonon dynamics of normal metal in the coherent regime of ultrafast spectroscopy is studied based on the non-equilibrium gauge invariant Green's function method. The non-equilibrium… Expand

Sinai Diffusion at Quasi-1D Topological Phase Transitions.

The expected manifestations of this transport mechanism for heat propagation in topological superconductors near criticality are discussed and a microscopic theory explaining the phenomenon is provided. Expand

Quantum dissipation in a scalar field theory with gapped momentum states

- Physics, Medicine
- Scientific Reports
- 2019

This work treats dissipation non-perturbatively, represents it by a bilinear term in the Lagrangian and quantize the theory, and finds that dissipation promotes a gap in momentum space and reduces the particle energy. Expand

Quench dynamics of one-dimensional interacting bosons in a disordered potential: elastic dephasing and critical speeding-up of thermalization.

- Physics, Medicine
- Physical review letters
- 2014

Thermalization turns out to be most effective close to the superfluid-Bose-glass critical point where nonlinearities become more and more important. Expand
