BCS-BEC crossover in an asymmetric two-component Fermi gas
– We discuss the superfluid phase transition of a strongly interacting Fermi gas with unequal (asymmetric) chemical potentials in two pairing hyperfine states, and map out its phase diagram near the BCS-BEC crossover. Our approach includes the fluctuation contributions of “preformed Cooper pairs” to the thermodynamic potential at finite temperature. We show that, below a critical difference in ...
متن کاملCritical temperature curve in BEC-BCS crossover.
The strongly correlated regime of the crossover from Bardeen-Cooper-Schrieffer pairing to Bose-Einstein condensation can be realized by diluting a system of two-component fermions with a short-range attractive interaction. We investigate this system via a novel continuous-space-time diagrammatic determinant Monte Carlo method and determine the universal curve Tc/epsilonF for the transition temp...
متن کاملDisorder Induced BCS–BEC Crossover in an Ultracold Fermi Gas
We develop the formalism for BCS–BEC crossover in the presence of weak random impurity and calculate the effect of the random potentials on the basic mean-field quantities. The disorder has been included through the Nozières and Schmitt–Rink theory of superconducting fluctuations, and we obtain the disorder induced superfluid order parameter and chemical potential through a self-consistent calc...
متن کاملFinite-temperature collective dynamics of a Fermi gas in the BEC-BCS crossover.
We report on experimental studies on the collective behavior of a strongly interacting Fermi gas with tunable interactions and variable temperature. A scissors mode excitation in an elliptical trap is used to characterize the dynamics of the quantum gas in terms of hydrodynamic or near-collisionless behavior. We obtain a crossover phase diagram for collisional properties, showing a large region...
متن کاملRelativistic BCS-BEC crossover of a two-species Fermi gas with number density asymmetry at zero temperature
We systematically study relativistic two-species fermions with tunable attractive interactions and number-density asymmetry at zero temperature. In general, a BardeenCooper-Schrieffer (BCS) Bose-Einstein Condensation (BEC) relativistic BEC (RBEC) crossover is observed. A generalized BCS ground state and its stability are analyzed. The homogeneous superfluid phase can become unstable and we cons...
