Al'tshuler-Aronov-Spivak oscillations of bosonic matter-wave beams in the presence of interaction
Renaud Chrétien, Josef Rammensee, Julien Dujardin +2
We theoretically study the propagation of a guided atom laser across an Aharonov-Bohm ring which is exposed to a synthetic gauge field. The presence of disorder within the ring giv…

Many-Body Quantum Interference and the Saturation of Out-of-Time-Order Correlators
Josef Rammensee, Juan-Diego Urbina, Klaus Richter
Out-of-time-order correlators (OTOCs) have been proposed as sensitive probes for chaos in interacting quantum systems. They exhibit a characteristic classical exponential growth, b…
