Critical Temperature Shift in Weakly Interacting Bose Gas
Nikolay Prokof'ev, Boris Svistunov, V. A. Kashurnikov
With a high-performance Monte Carlo algorithm we study the interaction-induced shift of the critical point in weakly interacting three-dimensional -theory (which includes qu…

Quantum spin chains in a magnetic field
V. A. Kashurnikov, N. V. Prokof'ev, B. V. Svistunov +1
We demonstrate that the ``worm'' algorithm allows very effective and precise quantum Monte Carlo (QMC) simulations of spin systems in a magnetic field, and its auto-correlation tim…
