Influence of Induced Interactions on Superfluid Properties of Quasi-Two Dimensional Dilute Fermi Gases With Spin-Orbit Coupling

TL;DR

This paper investigates how induced interactions influence key superfluid properties like pairing gap, transition temperature, and chemical potential in quasi-two-dimensional Fermi gases with spin-orbit coupling, revealing significant modifications.

Contribution

It introduces a detailed analysis of induced interactions effects on superfluid parameters and their role in the BCS-BEC crossover in spin-orbit coupled Fermi gases.

Findings

Induced interactions significantly modify pairing gap and transition temperature.

Corrections impact the BCS-BEC crossover even at small binding energies.

Mean-field parameters are notably affected by induced interactions.

Abstract

We study the effects of induced interactions on the pairing gap, transition temperature and chemical potential of a quasi-two dimensional Fermi gas of atoms with spin-orbit coupling. We find that these mean-field parameters are significantly modified when induced interactions are taken into account. We also investigate the implications of induced interactions corrections for the BCS-BEC crossover driven by spin-orbit coupling, that happens even for small (compared to the Fermi energy) values of the binding energy.
