Spin nematic correlations in bilinear-biquadratic S=1 spin chains
Andreas Laeuchli, Guido Schmid, Simon Trebst
We present an extensive numerical study of spin quadrupolar correlations in single and coupled bilinear-biquadratic spin one chains, using several methods such as Exact Diagonaliza…
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…
The ALPS project: open source software for strongly correlated systems
F. Alet, P. Dayal, A. Grzesik +15
We present the ALPS (Algorithms and Libraries for Physics Simulations) project, an international open source software project to develop libraries and application programs for the…
Spin nematics in the bilinear-biquadratic S=1 spin chain
A. Laeuchli, G. Schmid, S. Trebst
We report the existence of an extended critical, nondimerized region in the phase diagram of the bilinear-biquadratic spin-one chain. The dominant power law correlations are ferroq…
On the Melting of Bosonic Stripes
Guido Schmid, Matthias Troyer
We use quantum Monte Carlo simulations to determine the finite temperature phase diagram and to investigate the thermal and quantum melting of stripe phases in a two-dimensional ha…
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…
