Direct observation of competition between superconductivity and charge density wave order in YBa2Cu3Oy
J. Chang, E. Blackburn, A. T. Holmes +10
Superconductivity often emerges in the proximity of, or in competition with, symmetry breaking ground states such as antiferromagnetism or charge density waves (CDW)1-5. A number o…
Emergent quantum confinement at topological insulator surfaces
M. S. Bahramy, P. D. C. King, A. de la Torre +8
Bismuth-chalchogenides are model examples of three-dimensional topological insulators. Their ideal bulk-truncated surface hosts a single spin-helical surface state, which is the si…
Bulk electronic structure of superconducting LaRu2P2 single crystals measured by soft x-ray angle-resolved photoemission spectroscopy
E. Razzoli, M. Kobayashi, V. N. Strocov +10
We present a soft X-ray angle-resolved photoemission spectroscopy (SX-ARPES) study of the stoichiometric pnictide superconductor LaRu2P2. The observed electronic structure is in go…
Spin density wave induced disordering of the vortex lattice in superconducting LaSrCuO
J. Chang, J. S. White, M. Laver +19
We use small angle neutron scattering to study the superconducting vortex lattice in LaSrCuO as a function of doping and magnetic field. We show that near optimally…
