Symmetry Protected Josephson Supercurrents in Three-Dimensional Topological Insulators
Sungjae Cho, Brian Dellabetta, Alina Yang +6
Coupling the surface state of a topological insulator (TI) to an s-wave superconductor is predicted to produce the long-sought Majorana quasiparticle excitations. However, supercon…
Collapse of the Fermi surface and fingerprints of order in the pseudogap state of cuprate superconductors
Takeshi Kondo, Ari Palczewski, Yoichiro Hamaya +6
The Fermi surface in the state of cuprates is highly unusual because it appears to consist of disconnected segments called arcs. Their very existence challenges the traditional con…
Thermal evolution of the full three-dimensional magnetic excitations in the multiferroic BiFeO3
Zhijun Xu, Jinsheng Wen, Tom Berlijn +8
The idea of embedding and transmitting information within the fluctuations of the magnetic moments of spins (spin waves) has been recently proposed and experimentally tested. The c…
Freezing of the local dynamics in the relaxor ferroelectric PZN-4.5PT
Zhijun Xu, Jinsheng Wen, E. Mamontov +3
We report measurements of the neutron diffuse scattering in a single crystal of the relaxor ferroelectric material 95.5%Pb(Zn1/3Nb2/3)O3-4.5%PbTiO3 (PZN-4.5%PT). We show that the d…
Disentangling a quantum antiferromagnet with resonant inelastic X-ray scattering
L. Andrew Wray, Ignace Jarrige, Kazuhiko Ikeuchi +11
Low-dimensional copper oxide lattices naturally manifest electronic states with strong short range quantum entanglement, which are known to lead to remarkable emergent material pro…
Temperature-dependent transformation of the magnetic excitation spectrum on approaching superconductivity in Fe1-x (Ni/Cu)x Te0.5 Se0.5
Zhijun Xu, Jinsheng Wen, Yang Zhao +8
Spin excitations are one of the top candidates for mediating electron pairing in unconventional superconductors. Their coupling to superconductivity is evident in a large number of…
