Authors: Munuera-Javaloy, C.; Puebla, R.; D'Anjou, B.; Plenio, M. B.; Casanova, J. Journal: NPJ QUANTUM INFORMATION Publication date: 2022/11/30 DOI: 10.1038/s41534-022-00653-w Abstract: We present a protocol that detects molecular conformational changes with two nitroxide electron-spin labels and a nitrogen-vacancy (NV) center in diamond. More specifically, we demonstrate that the NV can detect energy shifts induced [...]

Different routes to the classical limit of backflow

Authors: Mousavi, S., V; Miret-Artes, S. Journal: JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL Publication date: 2022/11/25 DOI: 10.1088/1751-8121/aca36e Abstract: Decoherence is a well established process for the emergence of classical mechanics in open quantum systems. However, it can have two different origins or mechanisms depending on the dynamics one is considering, speaking then about intrinsic [...]

Quantum dynamics in a single excitation subspace: deviations from eigenstate thermalization via long time correlations

Marcelo Castellanos2023-02-21T13:36:07+01:00Tags: Mathematical. , Multidisciplinary; Physics, Physics|

Authors: Nation, Charlie; Porras, Diego Journal: JOURNAL OF PHYSICS A-MATHEMATICAL AND THEORETICAL Publication date: 2022/11/25 DOI: 10.1088/1751-8121/aca3dc Abstract: In this work we study a scenario where unitary quantum dynamics in a many-body interacting system is restricted to a single excitation subspace. We ask how dynamics within to such a subspace may in general differ from [...]
