Coherent Population Trapping with a controlled dissipation: applications in optical metrology
L. Nicolas, T. Delord, P. Jamonneau +4
We analyze the properties of a pulsed Coherent Population Trapping protocol that uses a controlled decay from the excited state in a -level scheme. We study this problem analyti…
Spontaneous lateral atomic recoil force close to a photonic topological material
S. Ali Hassani Gangaraj, George W. Hanson, Mauro Antezza +1
We investigate the quantum recoil force acting on an excited atom close to the surface of a nonreciprocal photonic topological insulator (PTI). The main atomic emission channel is…
Fluctuation-induced forces on an atom near a photonic topological material
Mário G. Silveirinha, S. Ali Hassani Gangaraj, George W. Hanson +1
We theoretically study the Casimir-Polder force on an atom in a arbitrary initial state in a rather general electromagnetic environment wherein the materials may have a nonreciproc…
A self-contained quantum harmonic engine
Brendan Reid, Simon Pigeon, Mauro Antezza +1
We propose a system made of three quantum harmonic oscillators as a compact quantum engine for producing mechanical work. The three oscillators play respectively the role of the ho…
Casimir-Lifshitz Force for Nonreciprocal Media and Applications to Photonic Topological Insulators
Sebastian Fuchs, Frieder Lindel, Roman V. Krems +3
Based on the theory of macroscopic quantum electrodynamics, we generalize the expression of the Casimir force for nonreciprocal media. The essential ingredient of this result is th…
Giant Interatomic Energy-Transport Amplification with Nonreciprocal Photonic Topological Insulators
Pierre Doyeux, S. Ali Hassani Gangaraj, George W. Hanson +1
We show that the energy-transport efficiency in a chain of two-level emitters can be drastically enhanced by the presence of a photonic topological insulator (PTI). This is obtaine…
