Ultra-cold Polarized Fermi Gases

TL;DR

This paper reviews recent experimental advances in ultra-cold polarized Fermi gases, highlighting their significance for understanding fermionic superfluidity and related open problems in condensed matter physics.

Contribution

It provides a comprehensive discussion of how ultra-cold atom experiments inform longstanding questions about fermionic superfluids with spin imbalance.

Findings

Experimental realization of polarized fermionic superfluids

New insights into spin imbalance effects on superfluidity

Raised questions about fermionic pairing mechanisms

Abstract

Recent experiments with ultra-cold atoms have demonstrated the possibility of realizing experimentally fermionic superfluids with imbalanced spin populations. We discuss how these developments have shed a new light on a half- century old open problem in condensed matter physics, and raised new interrogations of their own.
