The physics of quantum degenerate atomic Fermi gases in uniform as well as in
harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is …

A central challenge in modern condensed matter physics is developing the tools for
understanding nontrivial yet unordered states of matter. One important idea to emerge in this …

We study the properties of the Bose polaron, an impurity strongly interacting with a Bose-
Einstein condensate, using a field-theoretic approach and make predictions for the spectral …

Ultracold atomic gases provide model systems in which to study many-body quantum
physics. Recent experiments using Fermi gases have demonstrated a phase transition to a …

This paper summarizes the experimental frontier of ultracold fermionic gases. It is based on
three lectures which one of the authors gave at the Varenna Summer School describing the …

We present some general considerations on the properties of a two-component ultracold
Fermi gas along the BEC-BCS crossover. It is shown that the interaction energy and the free …

A powerful set of universal relations, centered on a quantity called the contact, connects the
strength of short-range two-body correlations to the thermodynamics of a many-body system …

Many-body fermion systems are important in many branches of physics, including
condensed matter, nuclear, and now cold atom physics. In many cases, the interactions …

Recent experiments with ultra-cold atoms have demonstrated the possibility of realizing
fermionic superfluids with imbalanced spin populations experimentally. We discuss how …

We present an overview of recent developments in species-imbalanced ('polarized')
Feshbach-resonant Fermi gases. We summarize the current status of thermodynamics of …
