"The ultrastrong coupling regime, phenomenology and applications"


gio 16/01/2020 - 10:30 - Aula Rossa, Dipartimento di Fisica


The interaction between quantum systems is said to be in the strong
coupling (SC) regime when the coupling strength overcomes all dissipation
rates. Under this condition it is possible to observe a coherent exchange of
excitations within the system relaxation time. In the last decades, the
achievement of the SC regime in a variety of quantum optical systems has
allowed us to explore an extremely-rich phenomenology, and it has opened
the way to the practical implementation of quantum-information protocols.
Recent experimental advances have made it possible to reach values of the
coupling strength which are not only larger than dissipation rates, but even
comparable to the system bare frequencies. This condition marks the onset
of a novel interaction regime, called ultrastrong coupling (USC), which leads
to profound modifications of the system physical behaviour and to the
appearance of counter-intuitive phenomena. In this talk, I will present
theoretical results on ultrastrongly-coupled systems, in particular focusing on
the prediction of novel quantum-optical phenomena and to applications in
quantum sensing.
