Two-point measurement correlations beyond the quantum regression theorem
Leonardo Santos, Otfried Gühne, Stefan Nimmrichter
Temporal correlations are fundamental in quantum physics, yet their computation is often challenging. The regression theorem (or hypothesis) serves as a key tool in this context, o…

Thermodynamically consistent collisional master equation in a low-density gas with internal structure
Michael Gaida, Giulio Gasbarri, Stefan Nimmrichter
Quantum thermodynamics with open systems is often based on the quantum optical weak-coupling master equation or on operational repeated interaction models, whereas early works on t…

Quantum memory in spontaneous emission processes
Mei Yu, Ties-A. Ohst, Hai-Chau Nguyen +1
Quantum memory effects are essential in understanding and controlling open quantum systems, yet distinguishing them from classical memory remains challenging. We introduce a convex…
