Dr. Andrey Gorbach is a lecturer in Physics. He obtained PhD degree from Kharkov National University (Ukraine) in 2002. In the period 2002-2006 he did postdoctoral research at Linköping University (Sweden) and at Max-Planck Institute for the Physics of complex Systems (Germany). During that time, he was studying the phenomenon of dynamical localization in nonlinear lattice systems. His review paper on theory and applications of discrete breathers - generic type of nonlinear localized excitations supported by lattice models - is being highly cited at an average rate of 30 citations per year.
In 2006 Dr. Gorbach joined the Bath group as a research officer. Since then, his research has become mainly focused on nonlinear optics and plasmonics. In 2007 his discovery of the peculiar effect of light trapping by optical solitons has allowed to unveil the key mechanism behind optical supercontinuum generation – one of the most famous nonlinear optical effects, which has numerous applications. In 2006-2008, Dr. Gorbach initiated pioneering studies of the novel type of optical wave forms - spectral discrete solitons and spatio-temoral optical helices. Experimental studies of such waves has started recently in various groups worldwide. In collaboration with researchers from Bath, Jena and Tel-Aviv, Dr. Gorbach has been carrying out theoretical research of the novel type of half-light-half-matter microcavity solitons and vortices. These solitons have been recently observed experimentally with his active theoretical support.
In 2012 Dr. Gorbach was appointed to a lecturship in Bath. At the moment his research is aimed to explore the actively growing and prospective areas of nano-photonics – nonlinear plasmonics in metal/dielectric and grapene/dielectric structures.
