Unified description of dynamics of a repulsive two-component Fermi gas

PT Grochowski, T Karpiuk, M Brewczyk, K Rzążewski - Physical Review Letters, 2017 - APS
We study a binary spin mixture of a zero-temperature repulsively interacting Li 6 atoms using
both the atomic-orbital and density-functional approaches. The gas is initially prepared in a …

Numerical solution of the Boltzmann equation for the collective modes of trapped Fermi gases

Nonnegative magnetoresistance in hydrodynamic regime of electron fluid transport in two-dimensional materials

Y Huang, M Wang - Physical Review B, 2021 - APS
Electron transport in ultraclean two-dimensional materials has received much attention.
However, the sign of the magnetoresistance effect in various electron flow regimes remains …

Shape oscillations in nondegenerate Bose gases: Transition from the collisionless to the hydrodynamic regime

We investigate collective oscillations of nondegenerate clouds of Rb 87 atoms as a function
of density in an elongated magnetic trap. For the low-lying M= 0 monopole-quadrupole …

Nonequilibrium dynamics of an ultracold dipolar gas

AG Sykes, JL Bohn - Physical Review A, 2015 - APS
We study the relaxation and damping dynamics of an ultracold, but not quantum degenerate,
gas consisting of dipolar particles. These simulations are performed using a direct …

Collective modes of trapped Fermi gases with in-medium interaction

S Chiacchiera, T Lepers, D Davesne, M Urban - Physical Review A—Atomic …, 2009 - APS
Due to Pauli blocking of intermediate states, the scattering matrix (or T matrix) of two
fermionic atoms in a Fermi gas becomes different from that of two atoms in free space. This …
