Fast computation of spherical phase-space functions of quantum many-body states
Bálint Koczor, Robert Zeier, Steffen J. Glaser
Quantum devices are preparing increasingly more complex entangled quantum states. How can one effectively study these states in light of their increasing dimensions? Phase spaces s…

Continuous phase spaces and the time evolution of spins: star products and spin-weighted spherical harmonics
Bálint Koczor, Robert Zeier, Steffen J. Glaser
We study continuous phase spaces of single spins and develop a complete description of their time evolution. The time evolution is completely specified by so-called star products.…
