Valence Bond Glass Theory of Electronic Disorder and the Pseudogap State of High-Temperature Cuprate Superconductors

Origin of the Pseudogap in High-Temperature Cuprate Superconductors

Computational details Calculations to compute the pseudogap (PG) from Equation 1 were performed by averaging 100 ensembles of 2,500 x 2,500 lattices. Four-site plaquettes were randomly doped up to x = 0.187, then three-site plaquettes up to x = 0.226, followed by two-site plaquettes to x = 0.271, and finally one-site plaquettes were doped until no d spins remained at x = 0.317. The details of t...

The ground state of the pseudogap in cuprate superconductors.

We present studies of the electronic structure of La(2-x)BaxCuO4, a system where the superconductivity is strongly suppressed as static spin and charge orders or "stripes" develop near the doping level of x = (1/8). Using angle-resolved photoemission and scanning tunneling microscopy, we detect an energy gap at the Fermi surface with magnitude consistent with d-wave symmetry and with linear den...

The Electronic Nature of High Temperature Cuprate Superconductors

We review the field of high temperature cuprate superconductors, with an emphasis on the nature of their electronic properties. After a general overview of experiment and theory, we concentrate on recent results obtained by angle resolved photoemission, inelastic neutron scattering, and optical conductivity, along with various proposed explanations for these results. We conclude by reviewing ef...
