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…
A Strange Metal from Gutzwiller correlations in infinite dimensions
Wenxin Ding, Rok Žitko, Peizhi Mai +2
Recent progress in extremely correlated Fermi liquid theory (ECFL) and dynamical mean field theory (DMFT) enables us to compute in the limit the resistivity of the $…
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…
Transport and Optical Conductivity in the Hubbard Model: A High-Temperature Expansion Perspective
Edward Perepelitsky, Andrew Galatas, Jernej Mravlje +4
We derive analytical expressions for the spectral moments of the dynamical response functions of the Hubbard model using the high-temperature series expansion. We consider generic…
