Supersolids versus phase separation in two-dimensional lattice bosons
Pinaki Sengupta, Leonid P. Pryadko, Fabien Alet +2
We study the nature of the ground state of the strongly-coupled two dimensional extended boson Hubbard model on a square lattice. We demonstrate that strong but finite on-site inte…

Phase Diagram of a Spin Ladder with Cyclic Four Spin Exchange
A. Laeuchli, G. Schmid, M. Troyer
We present the phase diagram of the Heisenberg model on the two leg ladder with cyclic four spin exchange, determined by a combination of Exact Diagonalization and Density…
