Extensive mixed-state entanglement in kinetically constrained superradiance
Lucas Winter, Jan Kumlin, Thomas Pohl +1
Dicke superradiance by an ensemble of quantum emitters produces a collective burst of radiation, but no entanglement in the mixed state of the emitters. We show that adding a local…

Interaction-Mediated Non-Reciprocal Dynamics in Open Quantum Systems: From an Exactly Solvable Model to Generic Behavior
Pietro Borchia, Johannes Knolle, Andreas Nunnenkamp
Reservoir engineering has emerged as a powerful paradigm to realize non-reciprocal dynamics in open quantum many-body systems. Here, we show that density-density interactions can t…

DysonNet: Constant-Time Local Updates for Neural Quantum States
Lucas Winter, Andreas Nunnenkamp
Neural quantum states (NQS) provide a flexible variational framework for many-body wavefunctions, but suffer from high computational cost and limited interpretability. We introduce…
