 Welcome to the Condense Matter and Statistical Physics section at the International Center for Theoretical Physics, ICTP. Our section offers a unique international environment with people working on projects at the frontiers of science. The main research lines followed in our section include the physics of nanostructures, physics of many-body quantum systems at or far from equilibrium, computer simulations of fluids and solids with atomistic and molecular electronic structure methods, and finally the design of new materials for renewable energy applications. Our section is actively involved in the organization of many events ranging from conferences to schools which are hosted or sponsored by the ICTP around the world. The variance of the total energy with respect to the coefficient UK is equal to... Scientists in the Condense Matter and Statistical Physics section are actively involved in the organization and teaching of the pre-PhD diploma program, catering to students from developing countries. Many of our graduates have gone on to do PhDs at various prestigious universities. How does this relate to the usual Fermi Dirac distribution? Is there any relation between... Of course, in the limit when... The section also offers several visiting opportunities like short-term visits and the associates program, more details of which can be found on the ICTP website. Please don't hesitate to contact us for more details. Now, the main question is what happens when you add interaction to these particles?
