WebFeb 18, 2011 · We studied the effect of strong electron correlations on an oxide 2DEG by inserting a single atomic layer of R O ( R is La, Pr, Nd, Sm, or Y) into an epitaxial SrTiO 3 matrix using pulsed-laser deposition with atomic layer control. The R O layer donates electrons to the conduction band of SrTiO 3. WebIn thinking about the future of the correlated electron problem, myriad questions abound. Is a general framework to understand strong electronic correlations possible? Are numerical approaches essential? Can we make predictions? What new experiments can we design that give essential insight to heretofore unrecognized correlations?

WebJul 16, 2000 · For metals with strong electronic correlations a frequently observed scenario is the presence of longlived quasi-particles representing a coherent Fermi liquid picture at … WebSep 23, 2016 · In the static correlation, we use combination of Slater determinants to account for electronic correlation (known as CI or configuration interaction) and the wave function is represented as a sum of various SD where the HF SD is the base function and higher excited SD contributes some parts. Electronic correlation is the interaction between electrons in the electronic structure of a quantum system. The correlation energy is a measure of how much the movement of one electron is influenced by the presence of all other electrons.
