Low-energy phonons in BiSrCaCuO and their possible interaction with electrons measured by inelastic neutron scattering
A. M. Merritt, J. -P. Castellan, T. Keller +4
Electron-phonon interaction in copper oxide superconductors is still enigmatic. Strong coupling for certain optic phonons is now well established experimentally, but theoretical un…
Broken relationship between superconducting pairing interaction and electronic dispersion kinks in LSCO
S. R. Park, Y. Cao, Q. Wang +5
Electronic band dispersions in copper oxide superconductors have kinks around 70 meV that are typically attributed to coupling of electrons to a bosonic mode. We performed angle re…
Electron Removal Self Energy and its application to Ca2CuO2Cl2
Chul Kim, S. R. Park, C. S. Leem +5
We propose using the self energy defined for the electron removal Green's function. Starting from the electron removal Green's function, we obtained expressions for the removal sel…
Fate of the Peak Effect in a Type-II Superconductor: Multicriticality in the Bragg-Glass Transition
S. R. Park, S. M. Choi, D. C. Dender +2
We have used small-angle-neutron-scattering (SANS) and ac magnetic susceptibility to investigate the global magnetic field H vs temperature T phase diagram of a single crystal Nb i…
Direct Observation of Superheating and Supercooling of Vortex Matter using Neutron Diffraction
X. S. Ling, S. R. Park, B. A. McClain +3
We report the first observation of a striking history dependence of the structure function of the vortex matter in the peak effect regime in a Nb single crystal by using small angl…
