Summary

 

Summary

Alex's research is in the field of theoretical condensed matter physics. It is concerned particularly with systems where the inter-electron interactions are very strong so that conventional perturbation methods for the calculation of the electronic properties are not applicable, and non-perturbative methods are required.
