Sarma phase in relativistic and non-relativistic systems
Physics Letters B, 2015 We investigate the stability of the Sarma phase in two-component fermion systems in three spatial dimensions. For this purpose we compare strongly-correlated systems with either relativistic or non-relativistic dispersion relation: relativistic quarks ...

Condensed Matter, 2020 We investigate pairing fluctuation effects in a two band fermionic system, where a shallow band in the Bardeen−Cooper−Schrieffer−Bose−Einstein condensation (BCS-BEC) crossover regime is coupled with a weakly interacting deep band.

Optical spin conductivity in ultracold quantum gases
Physical Review Research, 2022 We show that the optical spin conductivity, which is a small ac response of a bulk spin current and elusive in condensed matter systems, can be measured in ultracold atoms. We demonstrate that this conductivity contains rich information on quantum states

Theory of ultracold Fermi gases
, 2007 The physics of quantum degenerate Fermi gases in uniform as well as in harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is given to the effect of interactions which play a crucial role, bringing the gas into a superfluid phase at low temperature.

Detecting quadrupole interactions in ultracold Fermi gases [PDF]
Physical Review A, 2014 We propose to detect quadrupole interactions of neutral ultra-cold atoms via their induced mean-field shift. We consider a Mott insulator state of spin-polarized atoms in a two-dimensional optical square lattice. The quadrupole moments of the atoms are aligned by an external magnetic field. As the alignment angle is varied, the mean-field shift shows a

Dispersion of First Sound in a Weakly Interacting Ultracold Fermi Liquid
Annalen der Physik, Volume 537, Issue 11, November 2025.The weak‐interaction, low‐temperature region of the phase diagram of a Fermi gas the so‐called Fermi liquid regime, which has been somewhat overlooked in ultracold gases‐is investigated. Precise and measurable predictions are presented for the viscosity and dispersion of first sound to leading order in the scattering length.

Neural-network quantum states for ultra-cold Fermi gases
Communications PhysicsUltra-cold Fermi gases exhibit a rich array of quantum mechanical properties, including the transition from a fermionic superfluid Bardeen-Cooper-Schrieffer (BCS) state to a bosonic superfluid Bose-Einstein condensate (BEC). While these properties can be

Synthetic topological Kondo insulator in a pumped optical cavity
New Journal of Physics, 2018 Motivated by experimental advances on ultracold atoms coupled to a pumped optical cavity, we propose a scheme for synthesizing and observing the Kondo insulator in Fermi gases trapped in optical lattices.
