Commensurability effects for fermionic atoms trapped in 1D optical lattices.
نویسندگان
چکیده
Fermionic atoms in two different hyperfine states confined in optical lattices show strong commensurability effects due to the interplay between the atomic density wave ordering and the lattice potential. We show that spatially separated regions of commensurable and incommensurable phases can coexist. The commensurability between the harmonic trap and the lattice sites can be used to control the amplitude of the atomic density waves in the central region of the trap.

Quantum many particle systems in ring-shaped optical lattices.
In the present work we demonstrate how to realize a 1D closed optical lattice experimentally, including a tunable boundary phase twist. The latter may induce "persistent currents" visible by studying the atoms' momentum distribution. We show how important phenomena in 1D physics can be studied by physical realization of systems of trapped atoms in ring-shaped optical lattices. A mixture of boso...
متن کاملBose-Einstein condensation of particle-hole pairs in ultracold fermionic atoms trapped within optical lattices.
We investigate the Bose-Einstein condensation (BEC, superfluidity) of particle-hole pairs in ultracold fermionic atoms with repulsive interactions and arbitrary polarization, which are trapped within optical lattices. In the strongly repulsive limit, the dynamics of particle-hole pairs can be described by a hard-core Bose-Hubbard model. The insulator-superfluid and charge-density-wave- (CDW) su...
متن کاملBifermionic Superfluidity in Toroidal Optical Lattices
We consider a gas of neutral fermions trapped in a specific optical trap that provides a tight confinement of a Fermi gas in a torus with a potential periodic along the azimuthal direction. The effective model is interacting fermions moving in a periodic potential along the ring. We show that the model demonstrates a novel type of superfluidity different from the BCS mechanism. This pure 1D qua...
متن کاملLocal quantum criticality in confined fermions on optical lattices.
Using quantum Monte Carlo simulations, we show that the one-dimensional fermionic Hubbard model in a harmonic potential displays quantum critical behavior at the boundaries of a Mott-insulating region. A local compressibility defined to characterize the Mott-insulating phase has a nontrivial critical exponent. Both the local compressibility and the variance of the local density show universalit...
متن کاملT > 0 transport properties in integrable quantum lattice systems
We show that a generalized charge SU(2) symmetry of the one-dimensional (1D) Hubbard model in an infinitesimal flux φ generates half-filling states from metallic states which lead to a finite charge stiffness D(T ) at finite temperature T , whose T dependence we study. Our results are of general nature for many integrable quantum lattice systems, reveal the microscopic mechanisms behind their e...
