Checkerboard local density of states in striped domains pinned by vortices
Brian M Andersen, Per Hedegard, Henrik Bruus
Within a Green's function formalism we calculate the electronic structure around static extended magnetic and non-magnetic perturbations in a d-wave superconductor. In partucular,…
Electronic checkerboard pattern in striped racetrack domains: a consistent picture of recent neutron and STM experiments
Brian M. Andersen, Per Hedegard
We discuss recent elastic neutron scattering and scanning tunneling experiments on high-T_c cuprates exposed to an applied magnetic field. In particular we show that a physical pic…
The magnetic neutron scattering resonance of high-T_c superconductors in external magnetic fields: an SO(5) study
Niels Asger Mortensen, H. M. Ronnow, Henrik Bruus +1
The magnetic resonance at 41 meV observed in neutron scattering studies of Y Ba_2 Cu_3 O_7 holds a key position in the understanding of high-T_c superconductivity. Within the SO(5)…
SO(5) theory of insulating vortex cores in high- materials
Brian Møller Andersen, Henrik Bruus, Per Hedegård
We study the fermionic states of the antiferromagnetically ordered vortex cores predicted to exist in the superconducting phase of the newly proposed SO(5) model of strongly correl…
