A Microscopic View on the Mott transition in Chromium-doped V2O3
S. Lupi, L. Baldassarre, B. Mansart +18
V2O3 is the prototype system for the Mott transition, one of the most fundamental phenomena of electronic correlation. Temperature, doping or pressure induce a metal to insulator t…

Approximate solution of variational wave functions for strongly correlated systems: Description of bound excitons in metals and insulators
Balazs Hetenyi
An approximate solution scheme, similar to the Gutzwiller approximation, is presented for the Baeriswyl and the Baeriswyl-Gutzwiller variational wavefunctions. The phase diagram of…

Mean-field quantum phase transition in graphene and in general gapless systems
Ádám Bácsi, Attila Virosztek, László Borda +1
We study the quantum critical properties of antiferromagnetism in graphene at T=0 within mean-field (MF) theory. The resulting exponents differ from the conventional MF exponents,…
