The large variations in T c across the cuprate families is one of the major unsolved puzzles
in condensed matter physics and is poorly understood. Although there appears to be a great …

The electron–electron and electron–phonon interactions play an important role in correlated
materials, being key features for spin, charge and pair correlations. Thus, here we …

We present a determinant quantum Monte Carlo study of the competition between
instantaneous on-site Coulomb repulsion and retarded phonon-mediated attraction between …

We analyze the competition of magnetism and superconductivity in the two-dimensional
Hubbard model with a moderate interaction strength, including the possibility of …

Using a recently developed renormalization group method for fermionic superfluids, we
determine conditions for d-wave superconductivity in the ground state of the two …

We study the Holstein-Hubbard model at half filling to explore ordered phases including
superconductivity (SC), antiferromagnetism (AF), and charge order (CO) in situations where …

The field of quantum simulation, which aims at using a tunable quantum system to simulate
another, has been developing fast in the past years as an alternative to the all-purpose …

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 …

We study a multiorbital Hubbard–Su-Schrieffer-Heeger model for the one-dimensional (1D)
corner-shared cuprates in the adiabatic and nonadiabatic limits using exact diagonalization …

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 …
