We review the physics of pair-density wave (PDW) superconductors. We begin with a
macroscopic description that emphasizes order induced by PDW states, such as charge …

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 review the concepts and the present state of theoretical studies of spin-imbalanced
superfluidity, in particular the elusive Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) state, in the …

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 …

The orbital degree of freedom plays a fundamental role in understanding the unconventional
properties in solid state materials. Experimental progress in quantum atomic gases has …

Motivated by a realization of imbalanced Feshbach-resonant atomic Fermi gases, we
formulate a low-energy theory of the Fulde-Ferrell and the Larkin-Ovchinnikov (LO) states …

Spin-polarized attractive Fermi gases in one-dimensional (1D) optical lattices are expected
to be remarkably good candidates for the observation of the Fulde-Ferrell-Larkin …

Using exact continuous quantum Monte Carlo techniques, we study the zero-and finite-
temperature properties of a system of harmonically trapped one-dimensional spin-1 2 …
