Strongly correlated fermions after a quantum quench
S. R. Manmana, S. Wessel, R. M. Noack +1
Using the adaptive time-dependent density-matrix renormalization group method, we study the time evolution of strongly correlated spinless fermions on a one-dimensional lattice aft…
Supersolids in confined fermions on one-dimensional optical lattices
F. Karim Pour, M. Rigol, S. Wessel +1
Using quantum Monte Carlo simulations, we show that density-density and pairing correlation functions of the one-dimensional attractive fermionic Hubbard model in a harmonic confin…
Inhomogeneous quantum antiferromagnetism on periodic lattices
A. Jagannathan, R. Moessner, S. Wessel
We study quantum antiferromagnets on two-dimensional bipartite lattices. We focus on local variations in the properties of the ordered phase which arise due to the presence of ineq…
Simulations of ultracold bosonic atoms in optical lattices with anharmonic traps
Olivier Gygi, Helmut G. Katzgraber, Matthias Troyer +2
We report results of quantum Monte Carlo simulations in the canonical and the grand-canonical ensemble of the two- and three-dimensional Bose-Hubbard model with quadratic and quart…
Valence Bond Solids and Their Quantum Melting in Hard-Core Bosons on the Kagome Lattice
S. V. Isakov, S. Wessel, R. G. Melko +2
Using large scale quantum Monte Carlo simulations and dual vortex theory we analyze the ground state phase diagram of hard-core bosons on the kagome lattice with nearest neighbor r…
