Commensurability effects for fermionic atoms trapped in 1D optical lattices.
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 th...
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 کاملMajorana modes and p-wave superfluids for fermionic atoms in optical lattices.
The quest for realization of non-Abelian phases of matter, driven by their possible use in fault-tolerant topological quantum computing, has been spearheaded by recent developments in p-wave superconductors. The chiral p(x)+ip(y)-wave superconductor in two-dimensions exhibiting Majorana modes provides the simplest phase supporting non-Abelian quasiparticles and can be seen as the blueprint of f...
متن کامل‘Baryonic’ bound-state instability in trapped fermionic atoms
Sympathetic cooling of trapped fermionic gases [1] is likely to lead to the creation of degenerate Fermi gases in the near future. In magnetic traps, the fermion’s spin is locked to the field direction. However the advent [2,3] of optical traps holds the promise of degenerate Fermi gases with unquenched spins and hence a variety of nonideal Fermi gases. Already there has been some discussion of...
