New electronic phases often emerge in the proximity of a quantum critical point (QCP) - that is the point where the transition temperature of a collective phase transition is...

One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution...

This proposal is part of an ongoing project to relate the magnetic excitations to other electronic properties of the cuprate superconductors. We have recently proposed that the...

We propose to measure the collective spin excitations over a wide energy range in BaFe2-xCoxAs2 (x=0.22). This compound is one of the FeAs based superconductors which have...

A major problem in physics is the identification of the mechanism of high-temperature superconductivity. Many theories purport to explain the high-Tc phenomenon. In most...

Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron...
