Chirality at an exceptional point

Chirality of a single surviving mode of an exciton-polariton resonator driven to an exceptional point was demonstrated in our recent experimental and theoretical work. The research appeared in Physical Review Letters 120, 065301 (2018). The image below shows (a) the shape of the optically-induced resonator and (b) a chiral (vortex) mode.

The group warmly welcomes Maciej Pieczarka from from Wrocław University of Science and Technology in Poland. He is visiting our lab until mid-September, and is planning to do some really exciting experiments during this time.

News from PLMCN’18

Congratulations to Eli Estrecho on winning the 1st “Gold” award (500 EUR) for the best poster presentation entitled “Single-shot imaging of exciton-polariton condensates” at PLMCN18 conference (9-14 July 2017, Wuerzburg, Germany).

Warmest welcome to our new group member Maryam Boozarjmehr, who has officially started her experimental PhD project with us last week.

We are also pleased to congratulate our first PhD graduate Dr. Guangyao Li on commencing his postdoctoral research at University of Southampton, in the group of Prof. Alexey Kavokin.

Crompton travel award

We congratulate Eliezer Estrecho on winning the highly competitive RSPE Robert and Helen Crompton Travel Award! This award will support his travel to our collaborators in Japan, Germany, and USA in 2017.

Congratulations to Guangyao (Leo) Li on submitting his PhD thesis and to Daniel Comber-Todd on submitting and defending his Honours thesis. These are the first thesis completions in our group.

UPDATE: Daniel graduated with H1 (first class Honours) – well done!

mini-workshop

We will be hosting several of our collaborators  working in the areas of polaritonics and non-equilibrium physics from the 23rd of May until the 2nd of June. During these two weeks, our guests will give a series of informal seminars on their recent research and ‘blue-sky’ visions for the future. Our speakers are:

Prof. Matthew Davis, UQ, Australia

A/Prof. Tim Liew, NTU, Singapore

Dr. Tania Espinosa-Ortega, NTU, Singapore

Dr. Michael Fraser, RIKEN, Japan

Dr. Ivan Savenko, CTP, Korea

The seminars will run from 11 am to 12 pm in Le Couter Building Seminar Room (Level 3) on the 23rd, 24th, 25th, and 26th of May, and on the 31st of May.

We will post the detailed program on Friday the 20th of May. Watch this space!
