Variational study of hard-core bosons in a 2-D optical lattice using Projected Entangled Pair States (PEPS)
V. Murg, F. Verstraete, J. I. Cirac
We have studied the system of hard-core bosons on a 2-D optical lattice using a variational algorithm based on projected entangled-pair states (PEPS). We have investigated the grou…

Efficient evaluation of partition functions of frustrated and inhomogeneous spin systems
V. Murg, F. Verstraete, J. I. Cirac
We present a numerical method to evaluate partition functions and associated correlation functions of inhomogeneous 2--D classical spin systems and 1--D quantum spin systems. The m…
