Loop updates for quantum Monte Carlo simulations in the canonical ensemble
Stefan Rombouts, Kris Van Houcke, Lode Pollet
We present a new non-local updating scheme for quantum Monte Carlo simulations, which conserves particle number and other symmetries. It allows exact symmetry projection and direct…
Engineering Local optimality in Quantum Monte Carlo algorithms
Lode Pollet, Kris Van Houcke, Stefan M. A. Rombouts
Quantum Monte Carlo algorithms based on a world-line representation such as the worm algorithm and the directed loop algorithm are among the most powerful numerical techniques for…
Quantum Monte Carlo simulation in the canonical ensemble at finite temperature
Kris Van Houcke, Stefan Rombouts, Lode Pollet
A quantum Monte Carlo method with non-local update scheme is presented. The method is based on a path-integral decomposition and a worm operator which is local in imaginary time. I…
Consequences of the Pauli exclusion principle for the Bose-Einstein condensation of atoms and excitons
S. M. A. Rombouts, L. Pollet, K. Van Houcke
The bosonic atoms used in present day experiments on Bose-Einstein condensation are made up of fermionic electrons and nucleons. In this Letter we demonstrate how the Pauli exclusi…
