Overview of the Theory of Extremely Correlated Fermi Liquids
B Sriram Shastry
The Extremely Correlated Fermi Liquids (ECFL) theory is reviewed as a framework for understanding the - model in metallic systems close to the Mott insulating limit. This ove…
Band-edge quasiparticles from electron phonon coupling and resistivity saturation
E. Perepelitsky, B. S. Shastry
We address the problem of resistivity saturation observed in materials such as the A-15 compounds. To do so, we calculate the resistivity for the Hubbard-Holstein model in infinite…
Origin of Kinks in Energy Dispersion of Strongly Correlated Matter
Kazue Matsuyama, Edward Perepelisky, B Sriram Shastry
We investigate the origin of ubiquitous low energy kinks found in Angle Resolved Photoemission (ARPES) experiments in a variety of correlated matter. Such kinks are unexpected from…
Extremely Correlated Fermi Liquids
B. Sriram Shastry
We present the theory of an extremely correlated Fermi liquid (ECFL) with . This liquid has an underlying Fermi liquid (FL) Greens function that is further caparisoned…
Fidelity and superconductivity in two-dimensional t-J models
Marcos Rigol, B. Sriram Shastry, Stephan Haas
We compute the ground-state fidelity and various correlations to gauge the competition between different orders in two-dimensional t-J-type models. Using exact numerical diagonaliz…
Kinetic Antiferromagnetism in the Triangular Lattice
Jan O Haerter, B Sriram Shastry
We show that the motion of a single hole in the infinite Hubbard model with frustrated hopping leads to weak metallic antiferromagnetism of kinetic origin. An intimate relation…
