Cosmic-ray anti-deuterium and anti-helium have long been suggested as probes of dark matter, as their secondary astrophysical production was thought extremely scarce. But how does one actually predict the secondary flux? Anti-nuclei are…

In resonance fluorescence excitation experiments, light emitted from solid-state quantum emitters is typically filtered to eliminate the laser photons, ensuring that only red-shifted Stokes photons are detected. However, theoretical…

Two photon correlations are studied for a binary star system. It is investigated how the differential Hanbury Brown and Twiss (HBT) approach can be used in order to determine orbital parameters of a binary star.
