A two-dimensional electronic system forms at the interface between the band insulators,
LaAlO3 and SrTiO3. Samples fabricated until now have been found to be either magnetic or …

High-temperature superconductivity in copper oxides arises when a parent insulator
compound is doped beyond some critical concentration; what exactly happens at this …

We present a general hydrodynamic theory of transport in the vicinity of superfluid-insulator
transitions in two spatial dimensions described by “Lorentz”-invariant quantum critical points …

In conventional metallic superconductors such as aluminium, the large number of weakly
bounded Cooper pairs become phase-coherent as soon as they start to form. The cuprate …

Recent spectroscopic observations of ad-wave-like gap in stripe-ordered La 2-x Ba x CuO 4
with x= 1 8 have led us to critically analyze the anisotropic transport and magnetization …

In the cuprate superconductors, Nernst and torque magnetization experiments have
provided evidence that the disappearance of the Meissner effect at T c is caused by the loss …

We present new x-ray and neutron-scattering measurements of stripe order in La 1.875 Ba
0.125 CuO 4, along with low-field susceptibility, thermal conductivity, and specific-heat data …

We calculate the electrical and thermal conductivities and the thermoelectric coefficient of a
class of strongly interacting 2+ 1-dimensional conformal field theories with anti-de Sitter …

The underlying physics of the magnetic-field induced resistive state in lightly doped high-
temperature cuprate superconductorsremains a mystery. One interpretation is that the …

We calculate superfluid density for a dirty d-wave superconductor. The effects of impurity
scattering are treated within the self-consistent t-matrix approximation, in weak-coupling …
