When superconductivity crosses over: From BCS to BEC

Q Chen, Z Wang, R Boyack, S Yang, K Levin - Reviews of Modern Physics, 2024 - APS
New developments in superconductivity, particularly through unexpected and often
surprising forms of superconducting materials, continue to excite the community and …

Imbalanced Fermi gases at unitarity

KB Gubbels, HTC Stoof - Physics Reports, 2013 - Elsevier
We consider imbalanced Fermi gases with strong attractive interactions, for which Cooper-
pair formation plays an important role. The two-component mixtures consist either of …

Imbalanced feshbach-resonant fermi gases

L Radzihovsky, DE Sheehy - Reports on Progress in Physics, 2010 - iopscience.iop.org
We present an overview of recent developments in species-imbalanced ('polarized')
Feshbach-resonant Fermi gases. We summarize the current status of thermodynamics of …

Finite-temperature phase diagram of a polarized Fermi condensate

MM Parish, FM Marchetti, A Lamacraft, BD Simons - Nature Physics, 2007 - nature.com
The two-component Fermi gas is the simplest fermion system exhibiting superfluidity, and as
such is relevant to topics ranging from superconductivity to quantum chromodynamics …

Fluctuations and phase transitions in Larkin-Ovchinnikov liquid-crystal states of a population-imbalanced resonant Fermi gas

L Radzihovsky - Physical Review A—Atomic, Molecular, and Optical …, 2011 - APS
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 …

Fulde-Ferrell-Larkin-Ovchinnikov pairing in one-dimensional optical lattices

M Rizzi, M Polini, MA Cazalilla, MR Bakhtiari… - Physical Review B …, 2008 - APS
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 …

Fulde-Ferrell-Larkin-Ovchinnikov states in one-dimensional spin-polarized ultracold atomic Fermi gases

XJ Liu, H Hu, PD Drummond - Physical Review A—Atomic, Molecular, and …, 2007 - APS
We present a systematic study of quantum phases in a one-dimensional spin-polarized
Fermi gas. Three comparative theoretical methods are used to explore the phase diagram at …

Sarma phase in trapped unbalanced Fermi gases

KB Gubbels, MWJ Romans, HTC Stoof - Physical review letters, 2006 - APS
We consider a trapped unbalanced Fermi gas at nonzero temperatures where the superfluid
Sarma phase is stable. We determine, in particular, the phase boundaries between the …

Zero-temperature thermodynamics of asymmetric Fermi gases at unitarity

A Bulgac, MMN Forbes - Physical Review A—Atomic, Molecular, and Optical …, 2007 - APS
The equation of state of a dilute two-component asymmetric Fermi gas at unitarity is subject
to strong constraints, which affect the spatial density profiles in atomic traps. These …

Finite-temperature phase diagram of a spin-polarized ultracold Fermi gas in a highly elongated harmonic trap

XJ Liu, H Hu, PD Drummond - Physical Review A—Atomic, Molecular, and …, 2008 - APS
We investigate the finite-temperature properties of an ultracold atomic Fermi gas with spin
population imbalance in a highly elongated harmonic trap. Previous studies at zero …
