A Single Atom in Front of a Mirror is a Universal Reservoir Computer
Peter J. Ehlers, Phi Hung Nguyen, Kanu Sinha +4
Universal approximation in reservoir computing is typically associated with a class of reservoirs. We show that universality can be associated with a single reservoir, considering…
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…
Spontaneous Emission in the presence of Quantum Mirrors
Kanu Sinha, Jennifer Parra-Contreras, Annyun Das +1
Arrays of atoms coupled to waveguides can behave as mirrors. We consider an array of -type three-level atoms wherein preparing the atoms in one ground state or another leads to…
Fluctuation-induced Forces on Nanospheres in External Fields
Clemens Jakubec, Pablo Solano, Uroš Delić +1
We analyze the radiative forces between two dielectric nanospheres mediated via the quantum and thermal fluctuations of the electromagnetic field in the presence of an external dri…
