Non-Markovian delay-assisted sensing with waveguide-coupled quantum emitters
Prajit Dhara, Isack Padilla, Saikat Guha +2
We show that in a minimal setup of two waveguide-coupled quantum emitters, separated by long distances and subject to an external field, time-delayed feedback can be a resource for…

Casimir-Polder potential on an excited atom near an atomic array
Annyun Das, Kanu Sinha
We develop a microscopic description of the fluctuation-mediated Casimir-Polder (CP) shifts on a 'test' two-level atom placed near a two-dimensional atomic array of two-level atoms…

Non-Markovian spontaneous emission in a tunable cavity formed by atomic mirrors
Annyun Das, Pablo Solano, Kanu Sinha
We analyze the non-Markovian spontaneous emission dynamics of a two-level test atom placed in a cavity formed by two atomic arrays in a waveguide quantum electrodynamics (QED) setu…
