Quantum hydrodynamics of electron gases [PDF]
The Journal of Chemical Physics, 2010 Electron gases in metals are described as quantum charged Newtonian viscous fluids experiencing Ohmic Darcy friction on the solid lattice ions as well. The dispersion relation of the electron acoustic waves is derived, which shows the existence of new quantum diffusion processes. The electric double layer near a metal surface is studied, which exhibits

Probing and Manipulating Fermionic and Bosonic Quantum Gases with Quantum Light
Atoms, 2015 We study the atom-light interaction in the fully quantum regime, with the focus on off-resonant light scattering into a cavity from ultracold atoms trapped in an optical lattice. The detection of photons allows the quantum nondemolition (QND) measurement

Hubbard models and state preparation in an optical Lieb lattice
New Journal of Physics, 2021 Inspired by the growing interest in probing many-body phases in novel two-dimensional lattice geometries we investigate the properties of cold atoms as they could be observed in an optical Lieb lattice.

Quantum Criticality of one-dimensional multicomponent Fermi Gas with Strongly Attractive Interaction
, 2014 Quantum criticality of strongly attractive Fermi gas with $SU(3)$ symmetry in one dimension is studied via the thermodynamic Bethe ansatz (TBA) equations.The phase transitions driven by the chemical potential $\mu$, effective magnetic field $H_1$, $H_2$ (

Quantum simulation of conductivity plateaux and fractional quantum Hall effect using ultracold atoms
New Journal of Physics, 2015 We analyze the role of impurities in the fractional quantum Hall effect using a highly controllable system of ultracold atoms. We investigate the mechanism responsible for the formation of plateaux in the resistivity/conductivity as a function of the ...

Disordered structures in ultracold spin-imbalanced Fermi gas
New Journal of Physics, 2023 We investigate properties of spin-imbalanced ultracold Fermi gas in a large range of spin polarizations at low temperatures. We present results of microscopic calculations based on mean-field and density functional theory approaches, with no symmetry ...

Quantum lattice gases and their invariants [PDF]
, 1997 The one particle sector of the simplest one dimensional quantum lattice gas automaton has been observed to simulate both the (relativistic) Dirac and (nonrelativistic) Schroedinger equations, in different continuum limits.

Nonequilibrium steady states of ideal bosonic and fermionic quantum gases. [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2015 We investigate nonequilibrium steady states of driven-dissipative ideal quantum gases of both bosons and fermions. We focus on systems of sharp particle number that are driven out of equilibrium either by the coupling to several heat baths of different ...

New Journal of Physics, 2020 We show that attractive two-dimensional (2D) spinor Bose–Einstein condensates with helicoidal spatially periodic spin–orbit coupling (SOC) support a rich variety of stable fundamental solitons and bound soliton complexes.
