Superconducting pairing in resonant inelastic X-ray scattering
Yifei Shi, David Benjamin, Eugene Demler +1
We develop a method to study the effect of the superconducting transition on resonant inelastic X-ray scattering (RIXS) signal in superconductors with an order parameter with an ar…
Friedel Oscillations as a Probe of Fermionic Quasiparticles
Emanuele G. Dalla Torre, David Benjamin, Yang He +2
When immersed in a see of cold electrons, local impurities give rise to density modulations known as Friedel oscillations. In spite of the generality of this phenomenon, the exact…
Probing Competing and Intertwined Orders with Resonant Inelastic x-ray Scattering in the Hole-Doped Cuprates
David Benjamin, Israel Klich, Eugene Demler
We develop a formalism to study indirect resonant inelastic x-ray scattering (RIXS) in systems with itinerant electrons, accounting for the attraction between valence electrons and…
Variational Polaron Method for Bose-Bose Mixtures
David Benjamin, Eugene Demler
We study degenerate mixtures of "heavy" bosons and "light" superfluid bosons using a variational polaron transformation. We consider the Mott insulator-superfluid transition of the…
Quasiparticle Theory of Resonant Inelastic X-ray Scattering in high-T cuprates
David Benjamin, Israel Klich, Eugene Demler
We develop a formalism for calculating resonant inelastic x-ray scattering (RIXS) spectra in systems of itinerant electrons with arbitrary band structures, accounting for the effec…
Exploring Quasiparticles in High-Tc Cuprates Through Photoemission, Tunneling, and X-ray Scattering Experiments
Emanuele G. Dalla Torre, Yang He, David Benjamin +1
One of the key challenges in the field of high-temperature superconductivity is understanding the nature of fermionic quasiparticles. Experiments consistently demonstrate the exist…
Microscopic theory of resonant soft x-ray scattering in systems with charge order
David Benjamin, Dmitry Abanin, Peter Abbamonte +1
We present a microscopic theory of resonant soft x-ray scattering (RSXS) that accounts for the delocalized character of valence electrons. Unlike past approaches defined in terms o…
