  • Chair: Boris Svistunov and Synge Todo
  • Speakers
    • Synge Todo: Parallel Monte Carlo
      • Why large load imbalance for parallel tempering?
        • Dependence of CPU time on temperature requires fine-tuning
      • Multi-canonical ensemble
        • Weight depends on global properties of the system
    • Simon Trebst: Extended statistical ensembles
      • More than one variable? Possible, but no examples where it helps significantly
        • Energy/temperature are good choices for thermal phase transitions
        • Ising: energy allone suffices, cannot get better than N^2 behaviour
    • Anatoly Kuklov: Flowgram Method in QM
    • Matthias Troyer: The Sign Problem
    • Boris Svistunov
