Quasinormal mode expansion and the exact solution of the Cauchy problem for wave equations

Nikodem Szpak

Solutions for a class of wave equations with effective potentials are obtained by a method of a Laplace-transform. Quasinormal modes appear naturally in the solutions only in a spa…

Spontaneous emission of light from atoms: the model

P. Marecki, N. Szpak

We investigate (non-relativistic) atomic systems interacting with quantum electromagnetic field (QEF). The resulting model describes spontaneous emission of light from a two-level…
