Non-equilibrium Quantum Manipulation: from robust entanglement to quantum thermal machines

When: Monday, 24th November (2014), 12:00h
Place: Departamento de Física Teórica de la Materia Condensada, Facultad Ciencias, Module 5, Seminar Room (5th Floor).
Speaker: Mauro Antezza, Laboratoire Charles Coulomb, Université de Montpellier and Institut Universitaire de France – Paris.

We will discuss the behavior of one or more elementary quantum systems (atom, molecules, quantum dot, …) interacting with a stationary, simple and rich electromagnetic environment out of thermal equilibrium. We will show how the internal atomic dynamics can be deeply affected by the non equilibrium configuration leading to unexpected phenomena like a spontaneous inversion of population, new cooling mechanisms obtained by heating the system, and the possibility to create and protect entanglement in a stationary and robust way. Finally, we will discuss how this system may directly allow the realization of atomic quantum thermal machines, with high efficiency and a genuine quantum behavior.
