Possible realization of the Exciton Bose Liquid phase in a hard-core boson model with ring-only exchange interactions
Possible realization ring-only exchange interactions
2010/11/17
We investigate a hard-core boson model with ring-only exchanges on a square lattice, where a K1
term acts on 1×1 plaquettes and a K2 term acts on 1×2 and 2×1 plaquettes, with a goal of realizing a no...

Noise correlations are studied for systems of hard-core bosons in one-dimensional lattices. We use an exact numerical approach based on the Bose-Fermi mapping and properties of Slater determinants.We ...
