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 recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

This article reviews theoretical and experimental developments for one-dimensional Fermi
gases. Specifically, the experimentally realized two-component delta-function interacting …

Superconductivity and magnetism generally do not coexist. Changing the relative number of
up and down spin electrons disrupts the basic mechanism of superconductivity, where …

We have observed two-particle bound states of atoms confined in a one-dimensional matter
waveguide. These bound states exist irrespective of the sign of the scattering length …

We provide a general discussion on the importance of three-body Efimov physics for
strongly interacting ultracold quantum gases. Using the adiabatic hyperspherical …

We present highly accurate energy spectra and eigenfunctions of small 1D harmonically
trapped two-component Fermi gases with interspecies δ-function interactions, and analyze …

Elongated atom traps can confine ultracold gases in the quasi-one-dimensional regime. We
review both the theory of these atom waveguides and their experimental realizations, with …

We consider a heteronuclear fermionic mixture on the molecular side of an interspecies
Feshbach reso<? format?> nance and discuss atom-dimer scattering properties in uniform …

We investigate many-body properties of equally populated three-component fermions with
attractive three-body contact interaction in one dimension. A diagrammatic approach …
