Modified spin-wave theory with ordering vector optimization I: frustrated bosons on the spatially anisotropic triangular lattice
Philipp Hauke, Tommaso Roscilde, Valentin Murg +2
We investigate a system of frustrated hardcore bosons, modeled by an XY antiferromagnet on the spatially anisotropic triangular lattice, using Takahashi's modified spin-wave (MSW)…

Exploring frustrated spin-systems using Projected Entangled Pair States (PEPS)
V. Murg, F. Verstraete, J. I. Cirac
We study the nature of the ground state of the frustrated J1-J2 model and the J1-J3 model using a variational algorithm based on projected entangled-pair states (PEPS). By investig…
