Abstract

A bosonic condensate of exciton polaritons –  cavity photons strongly coupled to bound electron-hole pairs in a semiconductor – gives us an opportunity to study non-equilibrium, open-dissipative quantum systems on an accessible experimental platform. In recent years, the Polariton BEC group at the ANU has put a lot of effort into investigating fundamental properties of such systems by driving an exciton-polariton condensate to a high-density, interaction-dominated regime in optically induced traps. In this talk, I will review some of this effort, including our attempt to settle a controversy regarding the most basic parameter of this system – the strength of polariton-polariton interactions. 

About Australia - New Zealand Cold Atom Seminars

This new initiative hosts a seminar once a month for the Australia – New Zealand cold atom research community.  The purpose is to encourage and facilitate ongoing discussions and collaboration in the local community.  Talks should be less than 40 minutes in length to allow ample time for questions and discussion.

Seminars will be held on the last Friday of the month (except for December) at 1pm Melbourne time (which is normally 3pm New Zealand time).  While the primary format is online via Zoom, various institutions will host the seminar in local seminar rooms.  The Zoom link is https://uqz.zoom.us/j/88604569495

You can sign up for announcements for the seminars at this webpage:

Seminars are recorded, and past seminars can be accessed from this web page.
