Spatial coherence of trapped exciton-polariton condensates
Speaker: Dr Eli Estrecho
Affiliation: Australian National University
Abstract
Exciton-polaritons, which are hybrid particles consisting of cavity photons strongly coupled to electron-hole pairs in semiconductors, offer a valuable platform for studying non-equilibrium, open-dissipative, two-dimensional bosonic fluids. In this seminar, I will discuss the recent advancements made by the ANU Polariton BEC group in understanding the properties of exciton-polariton condensates confined in optically induced traps. Specifically, I will focus on our investigations of the spatial first-order correlation function in both pulsed and steady-state regimes. Through these experiments, we aim to gain further insights into the impact of interactions, energy relaxation rate, and the incoherent reservoir on the bosonic transition of exciton-polaritons.
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
