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…

Impurities in a trapped 1D Bose gas of arbitrary interaction strength: localization-delocalization transition and absence of self-localization
Dennis Breu, Eric Vidal Marcos, Martin Will +1
We discuss impurities in a one-dimensional Bose gas with arbitrary boson-boson and boson-impurity interactions. To fully account for quantum effects, we employ numerical simulation…
