Two-fluid coexistence and phase separation in a one dimensional model with pair hopping and density interactions
Lorenzo Gotta, Leonardo Mazza, Pascal Simon +1
We compute the phase diagram of a one-dimensional model of spinless fermions with pair-hopping and nearest-neighbor interaction, first introduced by Ruhman and Altman, using the de…
Two-fluid coexistence in a spinless fermions chain with pair hopping
Lorenzo Gotta, Leonardo Mazza, Pascal Simon +1
We show that a simple one-dimensional model of spinless fermions with pair hopping displays a phase in which a Luttinger liquid of paired fermions coexists with a Luttinger liquid…
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,…
