Charge order in the kagome lattice Holstein model: A hybrid Monte Carlo study
Owen Bradley, Benjamin Cohen-Stead, Steven Johnston +2
The Holstein model is a paradigmatic description of the electron-phonon interaction, in which electrons couple to local dispersionless phonon modes, independent of momentum. The mo…
A flexible class of exact Hubbard-Stratonovich transformations
Seher Karakuzu, Benjamin Cohen-Stead, Cristian D. Batista +2
We consider a class of Hubbard-Stratonovich transformations suitable for treating Hubbard interactions in the context of quantum Monte Carlo simulations. A tunable parameter al…
A hybrid Monte Carlo study of bond-stretching electron-phonon interactions and charge order in BaBiO
Benjamin Cohen-Stead, Kipton Barros, Richard Scalettar +1
The relationship between electron-phonon (-ph) interactions and charge-density-wave (CDW) order in the bismuthate family of high-temperature superconductors remains unresolved.…
Fast and scalable quantum Monte Carlo simulations of electron-phonon models
Benjamin Cohen-Stead, Owen Bradley, Cole Miles +3
We introduce methodologies for highly scalable quantum Monte Carlo simulations of electron-phonon models, and report benchmark results for the Holstein model on the square lattice.…
Dynamical tuning of the chemical potential to achieve a target particle number in grand canonical Monte Carlo simulations
Cole Miles, Benjamin Cohen-Stead, Owen Bradley +3
We present a method to facilitate Monte Carlo simulations in the grand canonical ensemble given a target mean particle number. The method imposes a fictitious dynamics on the chemi…
