SUMMARY:Hybrid systems with dispersion forces
DESCRIPTION:Over the last few years, a variety of hybrid quantum systems have been proposed and already experimentally demonstrated. The elementary building blocks of those systems are of different nature, each one has its own advantages and disadvantages; the key idea is to combine these different systems and build hybrid quantum structures that combine the advantages of each one of them.
In my talk, I will focus on various possible hybrid systems whose interaction mechanism is based on dispersion forces such as Casimir-Polder forces. I will describe a second-order effect involving surface polaritons and Rydberg atoms that could be used as system to create a sophisticated quantum circuit where the surface polaritons are used to transport information stored in the atoms. I will also discuss the possibility to combine ultracold atoms with graphene membranes. Temporal changes in the atomic state of the atomic cloud changes the Casimir-Polder interaction, thereby leading to the creation of a backaction force in the graphene sheet. This setup could provide a controllable way to engineer ripples in a graphene sheet.
