Eigenvector Expansion and Petermann Factor for Ohmically Damped Oscillators
Alec Maassen van den Brink, K. Young, M. H. Yung
Correlation functions in ohmically damped systems such as coupled harmonic oscillators or optical resonators can be expressed as a single sum over modes …
Linearized Perturbations of a Black Hole: Continuum Spectrum
P. T. Leung, Alec Maassen_van_den_Brink, K. W. Mak +1
Linearized perturbations of a Schwarzschild black hole are described, for each angular momentum , by the well-studied discrete quasinormal modes (QNMs), and in addition a con…
Hamiltonian and Linear-Space Structure for Damped Oscillators: II. Critical Points
S. C. Chee, Alec Maassen van den Brink, K. Young
The eigenvector expansion developed in the preceding paper for a system of damped linear oscillators is extended to critical points, where eigenvectors merge and the time-evolution…
Hamiltonian and Linear-Space Structure for Damped Oscillators: I. General Theory
S. C. Chee, Alec Maassen van den Brink, K. Young
The phase space of damped linear oscillators is endowed with a bilinear map under which the evolution operator is symmetric. This analog of self-adjointness allows properties f…
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…
Ambiguities in Quantizing a Classical System
Ian Redmount, Wai-Mo Suen, Kenneth Young
One classical theory, as determined by an equation of motion or set of classical trajectories, can correspond to many unitarily {\em in}equivalent quantum theories upon canonical q…
