We review exact numerical results for one-dimensional quantum systems with half-filled bands. The topics covered include Peierls transitions in Holstein, Fröhlich, Su-Schrieffer …
Interactions between electrons and phonons play a crucial role in quantum materials. Yet, there is no universal method that would simultaneously accurately account for strong …

DMRG ground state search algorithms employing symmetries must be able to expand virtual bond spaces by adding or changing symmetry sectors if these lower the energy. Traditional …

We present an extension of constrained-path auxiliary-field quantum Monte Carlo (CP- AFQMC) for the treatment of correlated electronic systems coupled to phonons. The …
We analyze the global ground-state (quantum) phase diagram of the one-dimensional spinful Holstein model at half filling as a function of the strength of the electron-phonon …
We present a compelling response of a low-dimensional strongly correlated system to an external perturbation. Using the time-dependent Lanczos method we investigate a …
Single-and two-particle excitation spectra of the one-dimensional, half-filled Holstein- Hubbard model are calculated using the continuous-time quantum Monte Carlo method. In …
We demonstrate that fermion-boson models with nonlocal interactions can be simulated at<? format?> finite band filling with the continuous-time quantum Monte Carlo method. We …
We introduce the SmoQyDEAC. jl package, a Julia implementation of the Differential Evolution Analytic Continuation (DEAC) algorithm [NS Nichols et al., Phys. Rev. E 106 …
