Autonomous optomechanical Maxwell Demon engine
Sander Stammbach, Giulio Gasbarri, Stefan Nimmrichter
We present a fully autonomous model of a mechanical Maxwell demon engine that converts heat absorbed by a qubit into population inversion in an attached quantum battery. A damped m…
Non-Markovian dynamics of the giant atom beyond the rotating-wave approximation
Mei Yu, Walter T. Strunz, Stefan Nimmrichter
We study the non-Markovian dynamics of a giant artificial atom coupled to a one-dimensional acoustic waveguide beyond the rotating-wave and weak-coupling approximations. By combini…
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…
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…
Otto cycles with a quantum planar rotor
Michael Gaida, Stefan Nimmrichter
We present two realizations of an Otto cycle with a quantum planar rotor as the working medium controlled by means of external fields. By comparing the quantum and the classical de…
Newton's laws of motion generating gravity-mediated entanglement
Marta Maria Marchese, Martin Plávala, Matthias Kleinmann +1
The interface between quantum theory and gravity represents still uncharted territory. Recently, some works suggested promising alternative approaches aimed at witnessing quantum f…
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…
Criticality-Enhanced Precision in Phase Thermometry
Mei Yu, H. Chau Nguyen, Stefan Nimmrichter
Temperature estimation of interacting quantum many-body systems is both a challenging task and topic of interest in quantum metrology, given that critical behavior at phase transit…
Tsirelson inequalities: Detecting cheating and quantumness in a single framework
Martin Plávala, Teiko Heinosaari, Stefan Nimmrichter +1
Quantumness refers to the peculiar and counterintuitive characteristics exhibited by quantum systems. Tsirelson inequalities have emerged as a powerful tool in quantum theory to de…
