Good plasmons in a bad metal
Francesco L. Ruta, Yinming Shao, Swagata Acharya +12
Correlated materials may exhibit unusually high resistivity increasing linearly in temperature, breaking through the Mott-Ioffe-Regel bound, above which coherent quasiparticles are…
On the Adequacy of the Dynamical Mean Field Theory for Low Density and Dirac Materials
Anqi Mu, Zhiyuan Sun, Andrew J. Millis
The qualitative reliability of the dynamical mean field theory (DMFT) is investigated for systems in which either the actual carrier density or the effective carrier density is low…
Optical Conductivity of the two dimensional Hubbard model: vertex corrections, emergent Galilean invariance and the accuracy of the single-site dynamical mean field approximation
Anqi Mu, Zhiyuan Sun, Andrew J. Millis
We compute the frequency dependent conductivity of the two dimensional square lattice Hubbard model at zero temperature as a function of density to second order in the interaction…
