Enhanced carrier binding and bond correlations in the Hubbard-Su-Schrieffer-Heeger model with dispersive optical phonons
Debshikha Banerjee, Alberto Nocera, Steven Johnston
Electron-phonon (e-ph) interactions play a crucial role in determining many properties of materials. In this context, the Su-Schrieffer-Heeger (SSH) model, where atomic motion modu…
Spectral signatures of residual electron pairing in the extended-Hubbard-Su-Schrieffer-Heeger model
Debshikha Banerjee, Alberto Nocera, George A. Sawatzky +2
We study the electron addition spectrum of the one-dimensional extended Hubbard-Su-Schrieffer-Heeger (HSSH) model in the dilute limit using the density matrix renormalization group…
Identifying and quantifying Su-Schrieffer-Heeger-like interactions with RIXS
Debshikha Banerjee, Jinu Thomas, Alberto Nocera +1
Su-Schrieffer-Heeger (SSH)-like electron-phonon (e-ph) interactions can drive the formation of light (bi)polarons and several novel states of matter. It is, therefore, prudent to d…
Theory of electron-phonon interactions in extended correlated systems probed by resonant inelastic x-ray scattering
Jinu Thomas, Debshikha Banerjee, Alberto Nocera +1
An emerging application of resonant inelastic x-ray scattering (RIXS) is the study of lattice excitations and electron-phonon (-ph) interactions in quantum materials. Despite th…
SmoQyDEAC.jl: A differential evolution package for the analytic continuation of imaginary time correlation functions
James Neuhaus, Nathan S. Nichols, Debshikha Banerjee +4
We introduce the SmoQyDEAC.jl package, a Julia implementation of the Differential Evolution Analytic Continuation (DEAC) algorithm [N. S. Nichols et al., Phys. Rev. E 106, 025312 (…
