Light-matter interaction in open cavities with dielectric stacks
Astghik Saharyan, Juan-Rafael Álvarez, Thomas H. Doherty +2
We evaluate the exact dipole coupling strength between a single emitter and the radiation field within an optical cavity, taking into account the effects of multilayer dielectric m…

Microscopic and phenomenological models of driven systems in structured reservoirs
Gian Luca Giorgi, Astghik Saharyan, Stéphane Guérin +2
We study the paradigmatic model of a qubit interacting with a structured environment and driven by an external field by means of a microscopic and a phenomenological model. The val…

Finite temperature fermionic condensate in a conical space with a circular boundary and magnetic flux
Aram A. Saharian, Eugênio R. Bezerra de Mello, Astghik A. Saharyan
We investigate the edge effects on the finite temperature fermionic condensate (FC) for a massive fermionic field in a (2+1)-dimensional conical spacetime with a magnetic flux loca…
