Nonequilibrium Quantum Systems: Divergence between Global and Local Descriptions by Pedro D. Manrique, Ferney Rodríguez, Luis Quiroga, Neil F. Johnson

“…The desire to understand such natural phenomena, as well as interpret the output from ultrafast experimental probes, creates an urgent need for accurate quantitative theories of open quantum systems. However it is unclear how best to generalize the well-established assumptions of an isolated system, particularly under nonequilibrium conditions. …”

On Limiting Distributions of Quantum Markov Chains by Chaobin Liu, Nelson Petulante

“…In a quantum Markov chain, the temporal succession of states is modeled by the repeated action of a “bistochastic quantum operation” on the density matrix of a quantum system. Based on this conceptual framework, we derive some new results concerning the evolution of a quantum system, including its long-term behavior. …”

Bootstrapping ground state correlators in matrix theory. Part I by Henry W. Lin, Zechuan Zheng

“…Abstract The D0-brane/Banks-Fischler-Shenker-Susskind matrix theory is a strongly coupled quantum system with an interesting gravity dual. We develop a scheme to derive bootstrap bounds on simple correlators in the matrix theory at infinite N at zero energy by imposing the supercharge equations of motion. …”

Spectral narrowing in the resonance fluorescence of a driven V-type quantum emitter near a two-dimensional plasmonic nanostructure array by Spyridon G. Kosionis, Vassilios Yannopapas, Emmanuel Paspalakis

“…We investigate the incoherent resonance fluorescence spectrum emitted by a three-level V-type quantum emitter, under the influence of a two-dimensional plasmonic nanosphere array. The V-type quantum system is driven by a coherent electromagnetic field whilst quantum interference effects in the spontaneous emission due to the presence of the plasmonic nanostructure are accounted for. …”
