Ising Deconfinement Transition Between Feshbach-Resonant Superfluids
S. Ejima, M. J. Bhaseen, M. Hohenadler +3
We investigate the phase diagram of bosons interacting via Feshbach-resonant pairing interactions in a one-dimensional lattice. Using large scale density matrix renormalization gro…

A Green's function decoupling scheme for the Edwards fermion-boson model
D M Edwards, S Ejima, A Alvermann +1
Holes in a Mott insulator are represented by spinless fermions in the fermion-boson model introduced by Edwards. Although the physically interesting regime is for low to moderate f…
