Resonant Inelastic X-Ray Scattering in Metals: A Diagrammatic Approach
A. M. Tsvelik, R. M. Konik, N. V. Prokof'ev +1
We develop a formalism to study the Resonant Inelastic X-ray Scattering (RIXS) response in metals based on the diagrammatic expansion for its cross section. The standard approach t…

Orthogonality catastrophe in Coulomb systems
Igor S. Tupitsyn, Nikolay V. Prokof'ev
The orthogonality catastrophe (OC) problem is considered solved for 50 years. It has important consequences for numerous dynamic phenomena in fermionic systems, including Kondo eff…
