Exactly solvable path integral for open cavities in terms of quasinormal modes
Alec Maassen van den Brink
We evaluate the finite-temperature Euclidean phase-space path integral for the generating functional of a scalar field inside a leaky cavity. Provided the source is confined to the…

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…
