Active quantum matter from monitored pure-state dynamics
Jacob F. Steiner, Felix von Oppen, Reinhold Egger
Quantum many-body systems coupled to out-of-equilibrium reservoirs can behave as active matter and exhibit signs of flocking. However, the resulting steady states are highly mixed…

From Kardar-Parisi-Zhang scaling to soliton proliferation in Josephson junction arrays
Mikheil Tsitsishvili, Reinhold Egger, Karsten Flensberg +1
We propose Josephson junction arrays as realistic platforms for observing nonequilibrium scaling laws characterizing the Kardar-Parisi-Zhang (KPZ) universality class, and space-tim…

Towards scalable active steering protocols for genuinely entangled state manifolds
Samuel Morales, Silvia Pappalardi, Reinhold Egger
We introduce and analyze an active steering protocol designed to target multipartite entangled states. The protocol involves multiple qubits subjected to weak Bell pair measurement…
