Coherent lattice dynamics distinguish Holstein and Su-Schrieffer-Heeger electron-phonon coupling
Debshikha Banerjee, Jinu Thomas, G. Alvarez +3
Ultrafast pump-probe spectroscopy provides a powerful means to investigate electron-phonon (e-ph) interactions in strongly correlated systems. Nevertheless, the question of how dif…
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…
Magnetic, charge, and bond order in the two-dimensional Su-Schrieffer-Heeger-Holstein model
Max Casebolt, Chunhan Feng, Richard T. Scalettar +2
Most nonperturbative numerical studies of electron-phonon interactions focus on model Hamiltonians where the electrons interact with a phonon branch via a single type of microscopi…
Properties of the non-linear Holstein polaron at finite doping and temperature
Shaozhi Li, E. A. Nowadnick, S. Johnston
We use determinant quantum Monte Carlo to study the single particle properties of quasiparticles and phonons in a variant of the two-dimensional Holstein model that includes an add…
The effects of non-linear electron-phonon interactions on superconductivity and charge-density-wave correlations
Shaozhi Li, S. Johnston
Determinant quantum Monte Carlo (DQMC) simulations are used to study non-linear electron-phonon interactions in a two-dimensional Holstein-like model on a square lattice. We examin…
