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…
An Autonomous Topological Pump
Julius Bohm, James Anglin, Michael Fleischhauer
Robust quantization of particle transport, as in a Thouless pump, is a hallmark of topological quantum systems with externally controlled system parameters. Here we instead propose…
Quantum Contact Processes on a Topological Lattice
Julius Bohm, Richard Schmidt, Michael Fleischhauer +1
Contact processes play an important role in classical non-equilibrium dynamics, describing the spreading of diseases, the dynamics of earthquakes and forest fires, and the distribu…
Dephasing enhanced transport of spin excitations in a two dimensional lossy lattice
Andrei Skalkin, Razmik Unanyan, Michael Fleischhauer
Noise is commonly regarded as an adverse effect disrupting communication and coherent transport processes or limiting their efficiency. However, as has been shown for example for s…
