Nonresonant B1g Raman scattering in the Hubbard model

Abstract

The numerically exact solution for nonresonant B1g Raman scattering is presented for the half-filled Hubbard model in infinite dimensions. This solution illustrates the modifications of the Raman response (in a system tuned through the quantum-critical point of a metal-insulator transition) due to Fermi-liquid properties in the metallic phase. In the insulating phase, we recover the predicted universal behavior, while we find the Raman response is quite anomalous on the metallic side of the transition. Our calculated results are similar to those measured in FeSi, SmB6, and underdoped cuprates.
