The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

The mechanism of superconductivity in cuprates remains one of the big challenges of
condensed matter physics. High-T c cuprates crystallize into a layered perovskite structure …

The opening of an energy gap in the electronic structure generally indicates the presence of
interactions. In materials with low carrier density and short screening length, long-range …

Using a tight-binding two-orbital (dx 2− y 2, d 3 z 2− r 2) model and a random phase
approximation treatment of the spin-fluctuation pairing vertex, we calculate the pairing …

Within the cuprate constellation, one fixed star has been the superconducting dome in the
quantum phase diagram of transition temperature vs. the excess charge on the Cu in the …

We have used atomic layer-by-layer oxide molecular beam epitaxy to grow epitaxial thin
films of L a 2− x C ax C u O 4 with x up to 0.5, greatly exceeding the solubility limit of Ca in …

Recent discovery of superconductivity at a transition temperature of 73 K in the doped
layered compound Ba 2 CuO 3+ x for x∼ 0.2 has generated a lot of interest. Experiments in …

The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

The local structure of the highly “overdoped” 95 K superconductor Sr2CuO3. 3 determined
by Cu K X-ray absorption fine structure (XAFS) at 62 K in magnetically oriented samples …

A crucial issue in cuprates is the extent and mechanism of the coupling of the lattice to the
electrons and the superconductivity. Here we report Cu K edge extended X-ray absorption …
