Effective model for the A 2 g Raman signal in URu 2 Si 2

Résumé

We propose an effective model to describe the A2g signal in Raman scattering experiments in the URu2Si2 compound. We follow the scheme proposed earlier by Khveshchenko and Wiegmann [Phys. Rev. Lett. 73, 500 (1994)] to calculate the A2g scattering vertex. We extract the imaginary part of a two-point current-current correlation function and compare it directly with the Raman response. We obtain an inelastic peak at the A2g channel owing to the interplay between a local staggered ordering and a possible quantum spin liquid behavior. Our results offer an explanation for the electronic Raman scattering experiments at the hidden order phase in URu2Si2 compound [
