Extremely correlated Fermi liquid theory meets Dynamical mean-field theory: Analytical insights into the doping-driven Mott transition
R. Zitko, D. Hansen, E. Perepelitsky +3
We consider a doped Mott insulator in the large dimensionality limit within both the recently developed Extremely Correlated Fermi Liquid (ECFL) theory and the Dynamical Mean-Field…
Electronic spectral properties of the two-dimensional infinite-U Hubbard model
Ehsan Khatami, Daniel Hansen, Edward Perepelitsky +2
A strong-coupling series expansion for the Green's function and the extremely-correlated Fermi liquid (ECFL) theory are used to calculate the moments of the electronic spectral fun…
Extremely Correlated Fermi Liquids: Self consistent solution of the second order theory
Daniel Hansen, B. Sriram Shastry
We present detailed results from a recent microscopic theory of extremely correlated Fermi liquids, applied to the t-J model in two dimensions. We use typical sets of band paramete…
Nature of Split Hubbard Bands at Low Densities
Daniel Hansen, Edward Perepelitsky, B Sriram Shastry
We present a numerical scheme for the Hubbard model that throws light on the rather esoteric nature of the Upper and Lower Hubbard bands that have been invoked often in literature.…
