Optical Analogue of the Dynamical Casimir Effect in a Dispersion-Oscillating Fibre
Stefano Vezzoli, Arnaud Mussot, Niclas Westerberg +6
The dynamical Casimir effect is the generation of pairs of real particles or photons from the vacuum as a result of a non-adiabatic change of a system parameter or boundary conditi…
Vacuum radiation and frequency-mixing in linear light-matter systems
Niclas Westerberg, Angus Prain, Daniele Faccio +1
Recent progress in photonics has led to a renewed interest in time-varying media that change on timescales comparable to the optical wave oscillation time. However, these studies t…
Observation of photon droplets and their dynamics
Kali E. Wilson, Niclas Westerberg, Manuel Valiente +4
We present experimental evidence of photon droplets in an attractive (focusing) nonlocal nonlinear medium. Photon droplets are self-bound, finite-sized states of light that are rob…
Comparison and pure infiniteness of crossed products
Xin Ma
Let be a continuous action of an infinite countable group on a compact Hausdorff space. We show that, under the hypothesis that the action is topologic…
