Effective action approach to strongly correlated fermion systems
R. Chitra, G. Kotliar
We construct a new functional for the single particle Green's function, which is a variant of the standard Baym Kadanoff functional. The stability of the stationary solutions to th…
Dynamical Mean Field Theory and Electronic Structure Calculations
R. Chitra, G. Kotliar
We formulate the dynamical mean field theory directly in the continuum. For a given definition of the local Green's function, we show the existence of a unique functional, whose st…
The Finite Temperature Mott Transition in the Hubbard Model in Infinite Dimensions
Marcelo J. Rozenberg, R. Chitra, G. Kotliar
We study the second order finite temperature Mott transition point in the fully frustrated Hubbard model at half filling, within Dynamical Mean Field Theory. Using quantum Monte Ca…
Effect of coulomb long range interactions on the Mott transition
R. Chitra, G. Kotliar
We reconsider the Mott transition problem in the presence of long range Coulomb interactions. Using an extended DMFT, that sums an important class of diagrams absent in ordinary DM…
