Laser cooling all the way down to Fermi superfluid

TL;DR

This paper demonstrates through numerical simulations that laser cooling can effectively cool fermionic gases below the superfluid transition temperature, reaching as low as 0.085T_F in a few seconds, including superfluid growth.

Contribution

It introduces a method for laser cooling fermions below the superfluid transition, incorporating superfluid growth self-consistently in simulations.

Findings

Laser cooling can reach temperatures as low as 0.085T_F.

Superfluid transition occurs at 0.35T_F with the proposed method.

Cooling process occurs within a few seconds.

Abstract

Numerical simulations for realistic experimental parameters demonstrate that laser cooling on the attractive side of the Feshbach resonance can drive fermions much below the superfluid transition. For the assumed set of experimental parameters the transition takes place at $0.35T_F$, and laser cooling can drive the system down to at least $0.085T_F$ in a time of a few seconds. Superfluid growth is self-consistently included in simulations.
