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 study of the manganese oxides, widely known as manganites, that exhibit the “colossal”
magnetoresistance effect is among the main areas of research within the area of strongly …

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

Lifting the valley degeneracy of monolayer transition metal dichalcogenides (TMDs) would
allow versatile control of the valley degree of freedom. We report a giant valley exciton …

Abstract One-dimensional (1D) interacting electrons are often described as a Luttinger
liquid,,–having properties that are intrinsically different from those of Fermi liquids in higher …

We present an experimental review of the nature of the pseudogap in the cuprate
superconductors. Evidence from various experimental techniques points to a common …

Pairing symmetry in the cuprate superconductors is an important and controversial topic.
The recent development of phase-sensitive tests, combined with the refinement of several …

The character of the ground state of an antiferromagnetic insulator is fundamentally altered
following addition of even a small amount of charge. The added charge is concentrated into …

We review the depinning and nonequilibrium phases of collectively interacting particle
systems driven over random or periodic substrates. This type of system is relevant to vortices …

The high-temperature copper oxide superconductors are of fundamental and enduring
interest. They not only manifest superconducting transition temperatures inconceivable 15 …
