Recently, two unusual features were theoretically predicted for the Raman response of out-of-plane phonons in magnetic two-dimensional materials hosting massive Dirac fermions. Fir…
Characterizing Mott Insulators in the Interacting One-Body Picture
Theo N. Dionne, Santiago Villodre, Mikel Iraola +1
The one-body picture underlies our understanding of weakly interacting solids but breaks down in strongly correlated systems. We develop a general framework, based on the single-pa…
