Discrete Symmetry Breaking Transitions Between Paired Superfluids
M. J. Bhaseen, S. Ejima, F. H. L. Essler +3
We explore the zero-temperature phase diagram of bosons interacting via Feshbach resonant pairing interactions in one dimension. Using DMRG (Density Matrix Renormalization Group) a…
Metal-insulator transition in the Edwards model
H. Fehske, S. Ejima, G. Wellein +1
To understand how charge transport is affected by a background medium and vice versa we study a two-channel transport model which captures this interplay via a novel, effective fer…
Dynamic density-density correlations in interacting Bose gases on optical lattices
S. Ejima, H. Fehske, F. Gebhard
In order to identify possible experimental signatures of the superfluid to Mott-insulator quantum phase transition we calculate the charge structure factor for the one-dim…
Magnetic Properties of the Second Mott Lobe in Pairing Hamiltonians
M. J. Bhaseen, S. Ejima, M. Hohenadler +4
We explore the Mott insulating state of single-band bosonic pairing Hamiltonians using analytical approaches and large scale density matrix renormalization group calculations. We f…
Dynamic properties of the one-dimensional Bose-Hubbard model
S. Ejima, H. Fehske, F. Gebhard
We use the density-matrix renormalization group method to investigate ground-state and dynamic properties of the one-dimensional Bose-Hubbard model, the effective model of ultracol…
