Non-Markovian dynamics of the giant atom beyond the rotating-wave approximation
Mei Yu, Walter T. Strunz, Stefan Nimmrichter
The paper presents numerically exact simulations of a giant artificial atom coupled to a one‑dimensional acoustic waveguide, capturing non‑Markovian effects beyond the rotating‑wav…
Probing the nonclassical dynamics of a quantum particle in a gravitational field
Martin Plávala, Stefan Nimmrichter, Matthias Kleinmann
In quantum mechanics, the time evolution of particles is given by the Schrödinger equation. It is valid in a nonrelativistic regime where the interactions with the particle can be…
Robust entanglement buffers based on SWAP interactions
Ye-Chao Liu, Otfried Gühne, Stefan Nimmrichter
Quantum entanglement is the essential resource for quantum communication and distributed information processing in a quantum network. However, the remote generation over a network…
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…
