SUSY Transformations for Quasinormal and Total-Transmission Modes of Open Systems
P. T. Leung, Alec Maassen van den Brink, W. M. Suen +2
Quasinormal modes are the counterparts in open systems of normal modes in conservative systems; defined by outgoing-wave boundary conditions, they have complex eigenvalues. The con…

Waves in Open Systems via Bi-orthogonal Basis
P. T. Leung, W. -M. Suen, C. P. Sun +1
Dissipative quantum systems are sometimes phenomenologically described in terms of a non-hermitian hamiltonian , with different left and right eigenvectors forming a bi-orthogon…
