Three new hot hydrogen-deficient pre-white dwarfs

Autor: Werner, Klaus, Reindl, Nicole, Pritzkuleit, Max, Geier, Stephan

We have detected three new hydrogen-deficient (H < 0.001 mass fraction) pre-white dwarfs (WDs) with helium-dominated atmospheres. The first object is a relatively cool PG1159 star (effective temperature Teff = 72,000 K) that has the lowest surface gr

Quantum computing in spin-adapted representations for efficient simulations of spin systems

Autor: Gandon, Anthony, Baiardi, Alberto, Rossmannek, Max, Dobrautz, Werner, Tavernelli, Ivano

Exploiting inherent symmetries is a common and effective approach to speed up the simulation of quantum systems. However, efficiently accounting for non-Abelian symmetries, such as the $SU(2)$ total-spin symmetry, remains a major challenge. In fact,
