Regularization of Complex Langevin Method
Zhenning Cai, Yang Kuang, Hong Kiat Tan
The complex Langevin method, a numerical method used to compute the ensemble average with a complex partition function, often suffers from runaway instability. We study the regular…
An entropic method for discrete systems with Gibbs entropy
Zhenning Cai, Jingwei Hu, Yang Kuang +1
We consider general systems of ordinary differential equations with monotonic Gibbs entropy, and introduce an entropic scheme that simply imposes an entropy fix after every time st…
