Zig-zag dynamics in a Stern-Gerlach spin measurement

Simon Krekels, Christian Maes, Kasper Meerts +1

The one-century-old Stern-Gerlach setup is paradigmatic for a quantum measurement. We visualize the electron trajectories following the Bohmian zig-zag dynamics. This dynamics was…

Dynamical de Sitter black holes in a quasi-stationary expansion

Aaron Beyen, Efe Hamamcı, Kasper Meerts +1

We revisit and improve the analytic study arXiv:1804.03462 of spherically symmetric but dynamical black holes in Einstein's gravity coupled to a real scalar field. We introduce a s…

Resetting photons

Guilherme Eduardo Freire Oliveira, Christian Maes, Kasper Meerts

Starting from a frequency diffusion process for a tagged photon which simulates relaxation to the Planck law, we introduce a resetting where photons lower their frequency at random…

Photon frequency diffusion process

Guilherme Eduardo Freire Oliveira, Christian Maes, Kasper Meerts

We introduce a stochastic multi-photon dynamics on reciprocal space. Assuming isotropy, we derive the diffusion limit for a tagged photon to be a nonlinear Markov process on freque…

Diffraction and interference with run-and-tumble particles

Christian Maes, Kasper Meerts, Ward Struyve

Run-and-tumble particles, frequently considered today for modeling bacterial locomotion, naturally appear outside a biological context as well, e.g. for producing waves in the tele…

On the derivation of the Kompaneets equation

Guilherme Eduardo Freire Oliveira, Christian Maes, Kasper Meerts

The relaxation of a photon bath to thermal equilibrium via Compton scattering with electrons is described in the Kompaneets equation (1956). The equation is mostly known from studi…

Wave mechanics for gravity with point-particles

Christian Maes, Kasper Meerts, Ward Struyve

We consider non-relativistic point-particles coupled to Einstein gravity and their canonical quantization. From the resulting Wheeler-DeWitt wave equation we determine a quantum ve…
