Overview

Dr. David Colas completed a Master's Degree at the Université Blaise Pascal (Clermont Ferrand, France) in 2013. He then received a PhD degree in theoretical physics from the Universidad Autónoma de Madrid (Spain) in 2016.

During his PhD, he worked in the field of exciton-polaritons under the supervision of Pr. Fabrice P. Laussy.

In 2016, he joined the group of Pr. Matt Davis at the University of Queensland as a Postdoctoral Research Fellow to work of several aspect of out-of-equilibirum physics, focussing on exciton-polariton and atomic condensates.

    The aim of this project is to theoretically study 1D Spin-orbit coupled Bose-Einstein condensates (SOCBECs in stationary or translational optical lattices, exploring the different regimes of interaction and their subsequent consequences on the condensate dynamics. The student will develop skills in computational physics through the resolution of coupled-Gross-Pitaevskii equations and the use of various spectral representations like the wavelet transform.
