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…
Topological phases of the interacting Su-Schrieffer-Heeger model: An analytical study
E. Di Salvo, A. Moustaj, C. Xu +4
The interacting SSH model provides an ideal ground to study the interplay between topologically insulating phases and electron-electron interactions. We study the polarization dens…
Quantum Sensing with Nanoelectronics: Fisher Information for an Applied Perturbation
George Mihailescu, Anthony Kiely, Andrew K. Mitchell
Quantum systems used for metrology can offer enhanced precision over their classical counterparts. The design of quantum sensors can be optimized by maximizing the quantum Fisher i…
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…
Many-body quantum interference route to the two-channel Kondo effect: Inverse design for molecular junctions and quantum dot devices
Sudeshna Sen, Andrew K. Mitchell
Molecular junctions -- whether actual single molecules in nanowire break junctions or artificial molecules realized in coupled quantum dot devices -- offer unique functionality due…
Tunable Quantum Criticality and Super-ballistic Transport in a `Charge' Kondo Circuit
Z. Iftikhar, A. Anthore, A. K. Mitchell +7
Quantum phase transitions are ubiquitous in many exotic behaviors of strongly-correlated materials. However the microscopic complexity impedes their quantitative understanding. Her…
