Recent developments in quantum Monte Carlo simulations with applications for cold gases

L Pollet - Reports on progress in physics, 2012 - iopscience.iop.org
This is a review of recent developments in Monte Carlo methods in the field of ultracold
gases. For bosonic atoms in an optical lattice we discuss path-integral Monte Carlo …

Ultracold bosons with short-range interaction in regular optical lattices

KV Krutitsky - Physics Reports, 2016 - Elsevier
During the last decade, many exciting phenomena have been experimentally observed and
theoretically predicted for ultracold atoms in optical lattices. This paper reviews these rapid …

Nonequilibrium phase transition of interacting bosons in an intra-cavity optical lattice

MR Bakhtiari, A Hemmerich, H Ritsch, M Thorwart - Physical review letters, 2015 - APS
We investigate the nonlinear light-matter interaction of a Bose-Einstein condensate trapped
in an external periodic potential inside an optical cavity which is weakly coupled to vacuum …

Tunable single-ion anisotropy in spin-1 models realized with ultracold atoms

WC Chung, J de Hond, J Xiang, E Cruz-Colón… - Physical Review Letters, 2021 - APS
Mott insulator plateaus in optical lattices are a versatile platform to study spin physics. Using
sites occupied by two bosons with an internal degree of freedom, we realize a uniaxial …

Lattice-supersolid phase of strongly correlated bosons in an optical cavity

Equilibration and prethermalization in the Bose-Hubbard and Fermi-Hubbard models

F Queisser, KV Krutitsky, P Navez, R Schützhold - Physical Review A, 2014 - APS
We study the Bose-Hubbard and Fermi-Hubbard models in the (formal) limit of large
coordination numbers Z≫ 1. Via an expansion into powers of 1/Z, we establish a hierarchy …

Supersolidity of lattice bosons immersed in strongly correlated Rydberg dressed atoms

Y Li, A Geißler, W Hofstetter, W Li - Physical Review A, 2018 - APS
Recent experiments have illustrated that long-range two-body interactions can be induced
by laser coupling atoms to highly excited Rydberg states. Stimulated by this achievement …
