【 摘 要 】

We propose an effective model to describe the A(2g) signal in Raman scattering experiments in the URu2Si2 compound. We follow the scheme proposed earlier by D. V. Khveshchenko and P. B. Wiegmann [Phys. Rev. Lett. 73, 500 (1994)] to calculate the A(2g) scattering vertex. We extract the imaginary part of the two-point current-current correlation function and compare it directly with the Raman response. We obtain an inelastic peak at the A(2g) 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 the URu2Si2 compound [Buhot et al., Phys. Rev. Lett.. 113, 266405 (2014)].
