Acoustically modulated media offer a versatile platform for dynamic control of laser light, but conventional implementations in solid or liquid phases are limited by optical damage thresholds and restricted spectral ranges. A gas-phase medium can overcome these limitations. [...]

We measured the spectral flux of the Class 5 Moonlander high harmonic generation source for two driver systems using similar pulse parameters, but at different central wavelength: a solid state multipass cell compressed Yb laser and an optical parametric amplifier system. Both laser systems provide 17W average power at 100kHz repetition rate at comparable pulse durations, 29fs vs 20fs FWHM. [...]

Maximizing the discovery potential of increasingly precise neutrino experiments will require an improved theoretical understanding of neutrino-nucleus cross sections over a wide range of energies. Low-energy interactions are needed to reconstruct the energies of astrophysical neutrinos from supernovae bursts and search for new physics using increasingly precise measurement of coherent elastic neutrino scattering.

Speisequark kennt jeder - aber was ist mit Top-Quark, dem schwersten bekannten Elementarteilchen? Obwohl es unteilbar und unendlich klein zu sein scheint, ist es ungefähr so schwer wie ein Gold-Atom. Diese und andere krasse Eigenschaften verleiten viele Forschende zu der Annahme, dass das Top-Quark der Schlüssel zu bahnbrechenden Entdeckungen, wie etwa Dunkler Materie, sein könnte [...]
