Disentangling multi-spin dynamic correlations in the Heisenberg spin- chain
V. K . Bhartiya, U. Kumar, T. Kim +8
Higher-order correlations are essential for understanding exotic phases and uncovering universal aspects of quantum dynamics. While inelastic neutron scattering provides well-estab…
The optical Su-Schrieffer-Heeger model on a triangular lattice
Max Casebolt, Sohan Malkaruge Costa, Benjamin Cohen-Stead +2
We study the triangular lattice optical Su-Schrieffer-Heeger (SSH) model using determinant quantum Monte Carlo. By varying the model's carrier concentration, electron-phonon coupli…
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…
