Work distribution for strongly coupled many-body open quantum systems
H. T. M. Nghiem, T. A. Costi, S. Campbell +1
The non-equilibrium quantum thermodynamics of many-body open systems is notoriously rich, especially in the strong-coupling regime where strong system-bath correlations develop and…
Synchronization in a dissipative quantum many-body system
B. Ãakmak, K. Sümer, S. Campbell +1
We study synchronization in the XX qubit chain subject to local or multi-local amplitude-damping noise. Analyzing the decoherence-free subspace (DFS) structure of the model, we sho…
Stability of emergent time periodicity in a few-body interacting system
Steve Campbell, Jens Eisert, Giacomo Guarnieri
We examine the onset and resilience of emergent time periodicity in a few-body all-to-all interacting Lipkin-Meshkov-Glick model, where one of the constituents is locally in contac…
Multiparameter critical quantum metrology with impurity probes
George Mihailescu, Abolfazl Bayat, Steve Campbell +1
Quantum systems can be used as probes in the context of metrology for enhanced parameter estimation. In particular, the delicacy of critical systems to perturbations can make them…
