Large-shift Raman scattering in insulating cuprate materials
… near the charge-transfer gap in insulating cuprate materials, including the T' phase materials (R2Cu04, R=Gd, Eu, Sm, Nd, Pr), T phase La2Cu04, and 123 phase PrBa2Cu3Cu06 and YBa2Cu3Cu06+x· For all of these materials, several features are observed near 12000 cm-1 (-1.5 eV) with A2g, B1g, and …

Exploring exotic superconducting order in La-based cuprate materials using Josephson interferometry
… devices for studying exotic superconducting materials, because the transmission of superconductivity through a junction depends on the difference in phase of the superconducting order parameter across the junction. We present the results of two measurements which involve the fabrication of …

Topics in the Theory of High-Temperature Superconductors
… of superconductivity in the hightemperature cuprate superconductors lies in the intriguing properties of the global phase diagram of the cuprate materials. In particular, strongly underdoped cuprates exhibit antiferromagnetic order, whereas moderately underdoped cuprate superconductors …

Josephson Interferometry Measurements in High-T(c) Grain Boundary Junctions
… at grain boundary interfaces in the high-Tc cuprate materials. The inherent properties of these Josephson junctions depend strongly on the pairing symmetry and the electronic structure at the interface and can be used to determine the pairing symmetry as well as the structure of the grain …

Manipulating superconductivity in cuprates with selective ultrafast excitation
… that govern the macroscopic properties of materials. These processes can now be accessed on their fundamental timescale---the attosecond to picosecond range. Most ultrafast measurements involve using high energy excitation to bring a system out of equilibrium and then probing the subsequent …
