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…

Non-Hermitian Numerical Renormalization Group: Solution of the non-Hermitian Kondo model
Phillip C. Burke, Andrew K. Mitchell
Non-Hermitian (NH) Hamiltonians describe open quantum systems, nonequilibrium dynamics, and dissipative processes. Although a rich range of single-particle NH physics has been unco…

Metrological symmetries in singular quantum multi-parameter estimation
George Mihailescu, Saubhik Sarkar, Abolfazl Bayat +2
The theoretical foundation of quantum sensing is rooted in the Cramér-Rao formalism, which establishes quantitative precision bounds for a given quantum probe. In many practical sc…
