Short bio

James joined the MPSD as a postdoc in December 2014. He is interested in using coherent lightmatter interactions as a means of manipulating the topological order of materials. To this end, he is investigating how light can be used to drive topological phase transitions in various materials by coupling to the lattice and electronic degrees of freedom.

James received a PhD in physics from Harvard University in 2014 working in Nuh Gedik’s research group (Massachusetts Institute of Technology). There he studied the physics of topological insulators using nonlinear optical and optoelectronic techniques. The work he is most known for is the generation of surface electrical currents in a topological insulator by driving the system with circularly polarised light (link).
