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 …

We review the physics of pair-density wave (PDW) superconductors. We begin with a
macroscopic description that emphasizes order induced by PDW states, such as charge …

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

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 …

We study the superconducting pairing correlations in the ground state of the doped Hubbard
model—in its original form without hopping beyond nearest neighbor or other perturbing …

We theoretically explore possible orders induced by weak repulsive interactions in twisted
bilayer transition metal dichalcogenides (eg, WSe 2) in the presence of an out-of-plane …

Unravelling competing orders emergent in doped Mott insulators and their interplay with
unconventional superconductivity is one of the major challenges in condensed matter …

Unidirectional (“stripe”) charge density wave order has now been established as a
ubiquitous feature in the phase diagram of the cuprate high-temperature superconductors …
