A class of higher order numerical methods for advancing the charged particles in a general electromagnetic field is developed based on processing technique.
In this work,we develop an hp-adaptive minimum action method(MAM).MAM plays a critical role to minimize the Freidlin-Wentzell action functional,which is the
In this talk,recently developed grid methods in our group for solving time-dependent and time-independent Schrodinger equation for electronic dynamics in mo
We analyze rigorously error estimates and compare numerically spatial/temporal resolution of various numerical methods for the discretization of the Dirac e
