Theory of Fano effect in cavity quantum electrodynamics

We propose a Markovian quantum master equation that can describe the Fano effect directly, by assuming standard cavity electrodynamics system. The framework allows us to generalize formula, applicable over weak- and strong-coupling regimes with pure dephasing. A formulation of its emission spectrum is also given in consistent manner. then find interference responsible for robust against This counterintuitive because impact is, general, severely reduced decoherence processes. Our approach thus provides basis theoretical treatments insights into open systems.Received 7 November 2020Accepted 25 December 2020DOI:https://doi.org/10.1103/PhysRevResearch.3.013037Published American Physical Society under terms Creative Commons Attribution 4.0 International license.
