Photonic crystals have recently became very attractive for photonic technology, that uses light instead of slow electrons as the information carriers replacing electronics in communications and information management. This project has the purpose to develop the fundamental concept of nonlinear photonic crystals and demonstrate their possible applications analysing the properties of the nonlinearity-induced light localization, nonlinear transmission, and frequency conversion in band-gap materials with the intensity-dependent optical response. This will allow the possibility realising in practice nonlinear switching even for sharply bent waveguides, providing an effective way to control the flow of light in band-gap photonic circuits.Read moreRead less

Searching for solvability in Statistical Mechanics and beyond using advanced Enumerative Combinatorics. Standard models in lattice statistical mechanics provide basic models of a large variety of physical systems from polymers to the spread of forest fires. The ability to write down some kind of solution to these problems provides inestimable insight into their generic and universal behaviour. This project aims to expand the types of "solution" that mathematicians and physicists can write down.

Algebraic structures such as quantized superalgebras are among the most important discoveries in mathematics and have applications in a wide range of physics. Internationally there has been recent excitement about vertex operators and representations of these algebraic structures and their applications to integrable systems and quantum field theory. I have made significant contributions to this rapidly expanding field, and will capitalize on this success. I will develop a comprehensive theory of these mathematical structures and their applications in the construction of correlation functions and form factors, and in so doing write a definitive monograph on the subject.Read moreRead less
Metallic nanograins: superconducting correlations, Josephson tunneling and conformal field theory. Experimental studies of aluminium grains which are a few nanometres in size have exposed unexpected physical characteristics, including pairing interactions which are responsible for bulk superconductivity. Our previous theoretical work has shown that precise information about these nanograins can be gained in the framework of the exact solution of the BCS model.

Experimental studies of aluminium grains which are a few nanometres in size have exposed unexpected physical characteristics, including pairing interactions which are responsible for bulk superconductivity. Our previous theoretical work has shown that precise information about these nanograins can be gained in the framework of the exact solution of the BCS model. This project will continue our work in this area with an emphasis on investigating the nature of Josephson tunneling between coupled nanograins.
