Pairing in spin chains and spinless fermions with next-nearest neighbour interactions
Lorenzo Gotta, Leonardo Mazza, Pascal Simon +1
We investigate the phase diagrams of a one-dimensional lattice model of fermions and of a spin chain with interactions extending up to next-nearest neighbour range. In particular,…
Mixtures of ultra-cold atoms in 1D disordered potentials
Francois Crepin, Gergely Zarand, Pascal Simon
We study interacting 1D two-component mixtures of cold atoms in a random potential, and extend the results reported earlier [{\it Phys. Rev. Lett.} {\bf 105}, 115301 (2010)]. We co…
Incompressible states of a two-component Fermi gas in a double-well optical lattice
François Crépin, Roberta Citro, Pascal Simon
We propose a scheme to investigate the effect of frustration on the magnetic phase transitions of cold atoms confined in an optical lattice. We also demonstrate how to get two-leg…
Disordered one-dimensional Bose-Fermi mixtures: The Bose-Fermi glass
François Crépin, Gergely Zaránd, Pascal Simon
We analyze an interacting Bose-Fermi mixture in a 1D disordered potential using a combination of renormalization group and variational methods. We obtain the complete phase diagram…
