The repulsive Hubbard model has been immensely useful in understanding strongly
correlated electron systems and serves as the paradigmatic model of the field. Despite its …

The Hubbard model is the simplest model of interacting fermions on a lattice and is of similar
importance to correlated electron physics as the Ising model is to statistical mechanics or the …

The combination of nontrivial band topology and symmetry-breaking phases gives rise to
novel quantum states and phenomena such as topological superconductivity, quantum …

Competing inhomogeneous orders are a central feature of correlated electron materials,
including the high-temperature superconductors. The two-dimensional Hubbard model …

We study magic angle graphene in the presence of both strain and particle-hole symmetry
breaking due to nonlocal interlayer tunneling. We perform a self-consistent Hartree-Fock …

The Hubbard model is widely believed to contain the essential ingredients of high-
temperature superconductivity. However, proving definitively that the model supports …

We report results of large-scale ground-state density matrix renormalization group (DMRG)
calculations on tt′-J cylinders with circumferences 6 and 8. We determine a rough phase …

X-ray techniques have been used for more than a century to study the atomic and electronic
structure in practically any type of material. The advent of correlated electron systems, in …

Twisted bilayer transition metal dichalcogenides have emerged as important model systems
for the investigation of correlated electron physics because their interaction strength, carrier …

Variational studies of the tJ model on the square lattice based on infinite projected-
entangled pair states confirm an extremely close competition between a uniform d-wave …
