A comparative determinant quantum Monte Carlo study of the acoustic and optical variants of the Su-Schrieffer-Heeger model
Sohan Malkaruge Costa, Benjamin Cohen-Stead, Andy Tanjaroon Ly +2
We compare the acoustic Su-Schrieffer-Heeger (SSH) model with two of its optical variants where the phonons are defined on either on the sites or bonds of the system. First, we dis…
Charge correlations suppress unconventional pairing in the Holstein model
Philip M. Dee, Benjamin Cohen-Stead, Steven Johnston +1
In a recent work by Schrodi . [Phys. Rev. B. , L140506 (2021)], the authors find an unconventional superconducting state with a sign-changing order pa…
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…
Robust charge-density wave correlations in the electron-doped single-band Hubbard model
Peizhi Mai, Nathan S. Nichols, Seher Karakuzu +4
There is growing evidence that the hole-doped single-band Hubbard and - models do not have a superconducting ground state reflective of the high-temperature cuprate supercond…
Stripe correlations in the two-dimensional Hubbard-Holstein model
Seher Karakuzu, Andy Tanjaroon Ly, Peizhi Mai +3
Several state-of-the-art numerical methods have observed static or fluctuating spin and charge stripes in doped two-dimensional Hubbard models, suggesting that these orders play a…
