Working examples of quantum simulator technologies today include extremely cold atoms trapped with lasers and magnetic fields and ions in electromagnetic traps. Photons and polaritons in light-matter systems have also recently emerged as a promising avenue and we are happy to be one of the leading groups in this area. With photons, exotic phenomena thought to exist only in strongly interacting electronic systems, such as Mott transitionsFractional Hall effectspin-charge separation,  interacting relativistic theories  and topological physics can be reproduced and understood in more detail. In addition to the “many-body stuff”,  he is also interested in the “few body” quantum effects found in nano-structures and cold ions systems interfaced with light. These hybrid systems are extremely interesting for the study of quantum effects like quantum interference and entanglement and for their potential use in building quantum memories and quantum processors. My work is mainly theoretical but we keep close contact with various experimental groups.
