Research interests

In the past decade there has been an increasing interest of the condensed matter physics community in an optically responsive quasiparticles known as polariton originating from the strong-coupling regime between light and matter (e.g. microcavity photon modes and quantum well excitons for exciton-polaritons). Being an extremely light and interactive bosonic particle due to its hybrid nature, it shows some astounding properties such as nonequilibrium Bose-Einstein condensation at temperatures higher than conventional cold atom condensates and even superconductors.

Currently, my research lies in the area of theoretically investigating and understanding the properties of strong light-matter interaction, polariton mean field dynamics described by generalized Gross-Pitaevskii / complex Ginzburg-Landau / complex nonlinear Schrödinger type of equations, and the possibilities of application in polaritonic devices. This includes superfluid dynamics, spin/polarization sensitive transport, topological phases, edge states, and exotic defect states such as vortices, half-vortices, solitons, half-solitons, domain walls, and skyrmions. Furthermore, multistable behavior in polariton systems, arising due to the nonlinear nature of polaritons, are of great interest due to its possible application in integrated light-matter circuitry. Advancements in creating polaritons electrically, as opposed to conventional optical methods, is an important step towards construction of low-powered opto-electronic devices with fast signal processing capabilities.

Associate Professor

Admission Tutor

 

Alberto Politi received the B.Eng. degree in Electrical Engineering and M.Phys. degree from the University of Pavia, Pavia (IT) in 2003 and 2005, respectively. He obtained his PhD degree at the Centre for Quantum Photonics, University of Bristol, Bristol (U.K) in 2010 where he demonstrated the first chip for quantum photonics, the first integrated optical quantum algorithm and other key ingredients for optical quantum technologies. After a postdoctoral position at the Center for Quantum Photonics, he was research assistant at the University of California, Santa Barbara (USA) from 2011 to 2013 working on solid-state quantum computing using silicon carbide colour centres. Alberto is currently Associate Professor in the School of Physics and Astronomy at Southampton, where he leads the Quantum nanoPhotonics Lab.
