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…

Quantum theory of fractional topological pumping of lattice solitons
Julius Bohm, Hugo Gerlitz, Christina Jörg +1
One of the hallmarks of topological systems is the robust quantization of particle transport. It is the origin of the integer-valued quantum Hall conductivity and a potential tool…
