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…
Quasinormal Modes of Optical Solitons
Christopher Burgess, Sam Patrick, Theo Torres +2
Quasinormal modes (QNMs) are essential for understanding the stability and resonances of open systems, with increasing prominence in black hole physics. We present here the first s…
Quantum vacuum emission from a refractive index front
Maxime Jacquet, Friedrich Koenig
A moving boundary separating two otherwise homogeneous regions of a dielectric is known to emit radiation from the quantum vacuum. An analytical framework based on the Hopfield mod…
Efficient generation of tunable photon pairs at 0.8 and 1.6 micrometer
Elliott J. Mason, Marius A. Albota, Friedrich Koenig +1
We demonstrate efficient generation of collinearly propagating, highly nondegenerate photon pairs in a periodically-poled lithium niobate cw parametric downconverter with an inferr…
