A new technique for grand canonical Monte Carlo simulation: Application in a hardhyphen;disk system

摘要

We present a new Monte Carlo approach which is capable to reduce significantly the twohyphen;phase coexistence region by constraining the system to remain fairly homogeneous in the transition region. This is achieved by introducing the chemical potential as an extra intensive thermodynamic variable in the canonical average. The technique developed was applied in a system containing 224 hard disks. The approach can, on the other hand, be applied in a general way to other systems.
