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…

Motion-induced directionality of collective emission in a non-chiral waveguide
Yoan Spahn, Jens Hartmann, Benedikt Saalfrank +3
We report the experimental observation of motion-induced directionality in collective atomic emission within a hollow-core waveguide, establishing a general principle: directional…
