Truncated Wigner approximation for spins in continuous phase space
Jens Hartmann, Tom Schlegel, Viktoria Noel +2
We review the truncated Wigner approximation (TWA) for spins as a computationally inexpensive numerical approximation method to describe interacting and / or dissipative many-body…

Imaginary-time evolution of interacting spin systems in the truncated Wigner approximation
Tom Schlegel, Dennis Breu, Michael Fleischhauer
We present a semiclassical phase-space method to calculate thermal and ground states of large interacting spin systems. To this end, we extend the recently developed truncated Wign…
