SUSY Transformations for Quasinormal Modes of Open Systems
P. T. Leung, Alec Maassen van den Brink, W. M. Suen +2
Supersymmetry (SUSY) in quantum mechanics is extended from square-integrable states to those satisfying the outgoing-wave boundary condition, in a Klein-Gordon formulation. This bo…

Jordan blocks and generalized bi-orthogonal bases: realizations in open wave systems
Alec Maassen van den Brink, K. Young
Dissipative systems can be described in terms of non-hermitian hamiltonians H, whose left eigenvectors f^j and right eigenvectors f_j form a bi-orthogonal system. Bi-orthogonal sys…
