Phase diagram of Bose-Fermi mixtures in one-dimensional optical lattices
Lode Pollet, Matthias Troyer, Kris Van Houcke +1
The ground state phase diagram of the one-dimensional Bose-Fermi Hubbard model is studied in the canonical ensemble using a quantum Monte Carlo method. We focus on the case where b…

Integrable models for asymmetric Fermi superfluids: Emergence of a new exotic pairing phase
J. Dukelsky, G. Ortiz, S. M. A. Rombouts +1
We introduce an exactly-solvable model to study the competition between the Larkin-Ovchinnikov-Fulde-Ferrell (LOFF) and breached-pair superfluid in strongly interacting ultracold a…

Optimal Monte Carlo Updating
L. Pollet, S. M. A. Rombouts, K. Van Houcke +1
Based on Peskun's theorem it is shown that optimal transition matrices in Markov chain Monte Carlo should have zero diagonal elements except for the diagonal element corresponding…
