Time Dependent Phase Space Filters
Description
This book introduces an interesting and alternative way to design absorbing boundary conditions (ABCs) for quantum wave equations, basically the nonlinear Schrödinger equation. The focus of this book is the application of the phase space filter approach to derive accurate radiation conditions for Schrödinger equations.
Researchers who are interested in partial differential equations and mathematical physics might find this book appealing.
