Variational treatment of the Shastry-Sutherland antiferromagnet using Projected Entangled Pair States (PEPS)
A. Isacsson, O. F. Syljuasen
We have applied a variational algorithm based on Projected Entangled Pair States (PEPS) to a two dimensional frustrated spin system, the spin-1/2 antiferromagnetic Heisenberg model…

Superfluid-insulator transitions of two-species Bosons in an optical lattice
A. Isacsson, Min-Chul Cha, K. Sengupta +1
We consider a realization of the two-species bosonic Hubbard model with variable interspecies interaction and hopping strength. We analyze the superfluid-insulator (SI) transition…

Multi-flavor bosonic Hubbard models in the first excited Bloch band of an optical lattice
A. Isacsson, S. M. Girvin
We propose that by exciting ultra cold atoms from the zeroth to the first Bloch band in an optical lattice, novel multi-flavor bosonic Hubbard Hamiltonians can be realized in a new…
