Optical torque on a two-level system near a strongly nonreciprocal medium
Optical torque on a two-level system near a strongly nonreciprocal medium
We investigate the quantum optical torque on an atom interacting with an inhomogeneous electromagnetic environment described by the most general linear constitutive relations. The atom is modeled as a two-level system prepared in an arbitrary initial energy state. Using the Heisenberg equation of motion (HEM) and under the Markov approximation, …
