Numerical study of metastability due to tunneling: The quantum string method
Tiezheng Qian, Weiqing Ren, Jing Shi +2
We generalize the string method, originally designed for the study of thermally activated rare events, to the calculation of quantum tunneling rates. This generalization is based o…

Probing Multi-Scale Energy Landscapes Using the String Method
Weinan E, Weiqing Ren, Eric Vanden-Eijnden
A novel and powerful method is presented for the study of rare switching events in complex systems with multiscale energy landscapes. The method performs an umbrella sampling of th…

Optimal Paths for Spatially Extended Metastable Systems Driven by Noise
E. Weinan, Weiqing Ren, Eric Vanden-Eijnden
The least action principle is exploited as a simulation tool to find the optimal dynamic path for spatially extended systems driven by a small noise. Applications are presented for…
