Spin-1/2 fermions on spin-dependent optical lattices
M. A. Cazalilla, A. F. Ho, T. Giamarchi
We study the phase diagram of one dimensional spin one-half fermionic cold atoms. The two ``spin'' species can have different hopping or mass. The phase diagram at equal densities…
Deconfinement in a 2D optical lattice of coupled 1D boson systems
A. F. Ho, M. A. Cazalilla, T. Giamarchi
We show that a two-dimensional (2D) array of 1D interacting boson tubes has a deconfinement transition between a 1D Mott insulator and a 3D superfluid for commensurate fillings and…
Instabilities in binary mixtures of one-dimensional quantum degenerate gases
M. A. Cazalilla, A. F. Ho
We show that one-dimensional binary mixtures of bosons or of a boson and a spin-polarized fermion are Luttinger liquids with the following instabilities: i) For different particle…
Small polarons and c-axis transport in highly anisotropic metals
A. F. Ho, A. J. Schofield
Motivated by the anomalous c-axis transport properties of the quasi two-dimensional metal, , and related compounds, we have studied the interlayer hopping of singl…
