Kosterlitz-Thouless transition of the quasi two-dimensional trapped Bose gas
Markus Holzmann, Werner Krauth
We present Quantum Monte Carlo calculations with up to N=576000 interacting bosons in a quasi two-dimensional trap geometry closely related to recent experiments with atomic gases.…
Renormalization group approach to exact sampling
Cedric Chanal, Werner Krauth
In this Letter, we use a general renormalization-group algorithm to implement Propp and Wilson's "coupling from the past" approach to complex physical systems. Our algorithm follow…
Off-diagonal long-range order, cycle probabilities, and condensate fraction in the ideal Bose gas
Maguelonne Chevallier, Werner Krauth
We discuss the relationship between the cycle probabilities in the path-integral representation of the ideal Bose gas, off-diagonal long-range order, and Bose--Einstein condensatio…
Depinning exponents of the driven long-range elastic string
Olaf Duemmer, Werner Krauth
We perform a high-precision calculation of the critical exponents for the long-range elastic string driven through quenched disorder at the depinning transition, at zero temperatur…
