Multicanonical molecular dynamics by variable-temperature thermostats and variable-pressure barostats
Cheng Zhang, Michael W. Deem
Sampling from flat energy or density distributions has proven useful in equilibrating complex systems with large energy barriers. Several thermostats and barostats are presented to…

Estimating statistical distributions using an integral identity
Cheng Zhang, Jianpeng Ma
We present an identity for an unbiased estimate of a general statistical distribution. The identity computes the distribution density from dividing a histogram sum over a local win…

Enhanced sampling in generalized ensemble with large gap of sampling parameter: case study in temperature space random walk
Cheng Zhang, Jianpeng Ma
We present an efficient sampling method for computing a partition function and accelerating configuration sampling. The method performs a random walk in the space, with bei…
