Analog Gravity Models with Microcavity Polaritons. 01/10/2016 - 31/05/2018

Abstract

The main objective of this project, and moreover the central idea, is to bring complex and difficult to comprehend systems within the reach of realistic quantum fluid experiments. Since phenomena related to cosmology are often extremely difficult, if not impossible, to study experimentally, it can be very stimulating to translate some of the problems to realistic analog experiments. The specific quantum fluid that we will consider is a quantum degenerate Bosonic gas of exciton-polaritons in semiconductor microcavities.

Analog Models with Microcavity Polaritons. 01/10/2013 - 30/09/2014

Abstract

In the present project, we will pursue the analogy between the physics of exciton-polaritons in microcavities and cosmological phenomena. Exciton-polaritons are hybrid particles that are half matter (exciton) and half light (photon). Thanks to their hybrid nature, they combine interactions with easy optical manipulation. In particular, the microcavity polariton physics allows studying analogs of the Einstein field equations with a cosmological constant. A second topic of cosmological interest that we plan to address is the creation of particles due to changing gravitational fields.
