Strongly Correlated Superconductivity: a plaquette Dynamical mean field theory study
We use cluster Dynamical Mean Field Theory to study the simplest models of correlated electrons, the Hubbard model and the t-J model. We use a plaquette embedded in a medium as a reference frame to compute and interpret the physical properties of these models. We study various observables such as electronic lifetimes, one electron spectra, optical conductivities, superconducting stiffness, and ...
متن کاملNonequilibrium dynamical mean-field theory of strongly correlated electrons
We present a review of our recent work in extending the successful dynamical mean-field theory from the equilibrium case to nonequilibrium cases. In particular, we focus on the problem of turning on a spatially uniform, but possibly time varying, electric field (neglecting all magnetic field effects). We show how to work with a manifestly gauge-invariant formalism, and compare numerical calcula...
متن کاملDynamical mean-field theory for strongly correlated inhomogeneous multilayered nanostructures
Dynamical mean field theory is employed to calculate the properties of multilayered inhomogeneous devices composed of semi-infinite metallic lead layers coupled via barrier planes that are made from a strongly correlated material (and can be tuned through the metal-insulator Mott transition). We find that the Friedel oscillations in the metallic leads are immediately frozen in and do not change...
متن کاملCellular Dynamical Mean Field Approach to Strongly Correlated Systems
Dynamical mean field theory (DMFT) has been very successful in describing many aspects of strongly correlated electron systems [1], and presently much effort is being put into implementing it for realistic calculations of material properties of solids [2]. This method is exact in the limit of infinite lattice coordination [3] and describes correctly local correlations including magnetically ord...
متن کاملEmbedding approach for dynamical mean-field theory of strongly correlated heterostructures
We present an embedding approach based on localized basis functions which permits an efficient application of the dynamical mean-field theory DMFT to inhomogeneous correlated materials, such as semi-infinite surfaces and heterostructures. In this scheme, the semi-infinite substrate leads connected to both sides of the central region of interest are represented via complex energy-dependent embed...
