Non-local quantum fluctuations and fermionic superfluidity in the imbalanced attractive Hubbard model
M. O. J. Heikkinen, D. -H. Kim, M. Troyer +1
We study fermionic superfluidity in strongly anisotropic optical lattices with attractive interactions utilizing the cluster DMFT method, and focusing in particular on the role of…
Critical Temperature of Interacting Bose Gases in Periodic Potentials

The superfluid transition of a repulsive Bose gas in the presence of a sinusoidal potential which represents a simple-cubic optical lattice is investigate using quantum Monte Carlo…
Ferromagnetism of a Repulsive Atomic Fermi Gas in an Optical Lattice: a Quantum Monte Carlo Study
S. Pilati, I. Zintchenko, M. Troyer
Using continuous-space quantum Monte Carlo methods we investigate the zero-temperature ferromagnetic behavior of a two-component repulsive Fermi gas under the influence of periodic…
Néel temperature and thermodynamics of the half-filled 3D Hubbard model by Diagrammatic Determinant Monte Carlo
E. Kozik, E. Burovski, V. W. Scarola +1
We study thermodynamics of the 3D Hubbard model at half filling on approach to the Néel transition by means of large-scale unbiased Diagrammatic Determinant Monte Carlo simulations…
Trapped Ultracold Bosons in Periodically Modulated Lattices
Jia-Wei Huo, Fu-Chun Zhang, Weiqiang Chen +2
Motivated by the recent rapid development of the field of quantum gases in optical lattices, we present a comprehensive study of the spectrum of ultracold atoms in a one-dimensiona…
Bosonic superfluid-insulator transition in continuous space
S. Pilati, M. Troyer
We investigate the zero-temperature phase diagram of interacting Bose gases in the presence of a simple cubic optical lattice, going beyond the regime where the mapping to the sing…
