Quantum backreaction effect in optical solitons
Sang-Shin Baak, Friedrich Koenig
Optical solitons classically are stationary solutions of the nonlinear Schrödinger equation. We perform a quantum field theoretic treatment by quantising a linearised fluctuation f…

Hyperboloidal Method for Quasinormal Modes of Non-Relativistic Operators
Christopher Burgess, Friedrich Koenig
The recently reported compactified hyperboloidal method has found wide use in the numerical computation of quasinormal modes, with implications for fields as diverse as gravitation…
