Magnetic field-induced soft mode in spin-gapped high-Tc superconductors
Brian M. Andersen, Olav F. Syljuasen, Per Hedegard
We present an explanation of the dynamical in-gap spin mode in LSCO induced by an applied magnetic field H as recently observed by J. Chang et al. Our model consists of a phenomeno…
Phonon-induced quadrupolar ordering of the magnetic superconductor TmNiBC
N. H. Andersen, J. Jensen, T. B. S. Jensen +6
We present synchrotron x-ray diffraction studies revealing that the lattice of thulium borocarbide is distorted below T_Q = 13.5 K at zero field. T_Q increases and the amplitude of…
Spin dynamics in the stripe phase of the cuprates
Brian M. Andersen, Per Hedegard
Within a model that supports stripe spin and charge order coexisting with a d-wave superconducting phase, we study the self-consistently obtained electronic structure a…
Recursion method for the quasiparticle structure of a single vortex with induced magnetic order
Linda Udby, Brian M. Andersen, Per Hedegard
We use a real-space recursion method to calculate the local density of states (LDOS) within a model that contains both d-wave superconducting and antiferromagnetic order. We focus…
Quantum interference between multiple impurities in anisotropic superconductors
Brian M. Andersen, Per Hedegard
We study the quantum interference between impurities in d-wave superconductors within a potential scattering formalism that easily applies to multiple impurities. The evolution of…
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…
