Biography
Vladimir A Gavrichkov has experience in the study of the electronic structure of strongly correlated materials: iron borates with spin S=5/2, manganites (S=2) and cuprates (S=1/2). His metal-insulator criterion creates a new conception of the dielectric state in doped materials with translational symmetry. He obtained the criterion as a result of the latest research in the field of many-electron effects in the electronic structure and exchange interaction of these materials. The approach is based on Hubbard’s quasiparticle picture and Wilson’s view on nature of the metal/dielectric state in itinerant electron system.
