Thermodynamics of Ultracold Fermions in Traps

چکیده

The ability to tune the strength of the attractive interaction in trapped Fermi gases is revealing the nature of superfluidity (and superconductivity) in a hitherto unexplored regime. Within the last few years we have witnessed the discovery of strongly interacting Fermi gases; over the last year we have found strong evidence for their superfluidity. These interacting gases appear at intermediate coupling and are the most complex. We do not know the nature of the fermionic and bosonic excitations and, until recently (1), measurements of temperature have been problematic, largely because of the absence of theoretical guidance. This paper probes these fundamental questions through studies of thermodynamics, leading to good quantitative agreement with experiment (1). cond-mat/0411090

Ultracold atomic Fermi-Bose mixtures in bichromatic optical dipole traps: a novel route to study fermion superfluidity

The study of low density, ultracold atomic Fermi gases is a promising avenue to understand fermion superfluidity from first principles. One technique currently used to bring Fermi gases in the degenerate regime is sympathetic cooling through a reservoir made of an ultracold Bose gas. We discuss a proposal for trapping and cooling of two-species Fermi-Bose mixtures into optical dipole traps made...

Critical temperature and thermodynamics of attractive fermions at unitarity.

The unitarity regime of the BCS-BEC crossover can be realized by diluting a system of two-component lattice fermions with an on-site attractive interaction. We perform a systematic-error-free finite-temperature simulation of this system by diagrammatic determinant Monte Carlo method. The critical temperature in units of Fermi energy is found to be T(C)/epsilonF=0.152(7). We also report the beha...

Thermodynamic properties of correlated fermions in lattices with spin-dependent disorder

Motivated by the rapidly growing possibilities for experiments with ultracold atoms in optical lattices, we investigate the thermodynamic properties of correlated lattice fermions in the presence of an external spindependent random potential. The corresponding model, a Hubbard model with spin-dependent local random potentials, is solved within dynamical mean-field theory. This allows us to pres...

Thermodynamics of interacting fermions in atomic traps.

We calculate the entropy in a trapped, resonantly interacting Fermi gas as a function of temperature for a wide range of magnetic fields between the BCS and Bose-Einstein condensation end points. This provides a basis for the important technique of adiabatic sweep thermometry and serves to characterize quantitatively the evolution and nature of the excitations of the gas. The results are then u...

Short-range correlations and cooling of ultracold fermions in the honeycomb lattice.

We use determinantal quantum Monte Carlo simulations and numerical linked-cluster expansions to study thermodynamic properties and short-range spin correlations of fermions in the honeycomb lattice. We find that, at half filling and finite temperatures, nearest-neighbor spin correlations can be stronger in this lattice than in the square lattice, even in regimes where the ground state in the fo...
