Microscopic and Macroscopic Signatures of Antiferromagnetic Domain Walls
R. Jaramillo, T. F. Rosenbaum, E. D. Isaacs +4
Magnetotransport measurements on small single crystals of Cr, the elemental antiferromagnet, reveal the hysteretic thermodynamics of the domain structure. The temperature dependenc…
Magnetic Excitation Spectrum of the Square Lattice S=1/2 Heisenberg Antiferromagnet K2V3O8
M. D. Lumsden, S. E. Nagler, B. C. Sales +4
We have explored the magnetic excitation spectrum of the S=1/2 square lattice Heisenberg antiferromagnet, K2V3O8 using both triple-axis and time-of-flight inelastic neutron scatter…
Magnetocaloric Study of Spin Relaxation in `Frozen' Dipolar Spin Ice Dy2Ti2O7
M. Orendac, J. Hanko, E. Cizmar +3
The magnetocaloric effect of polycrystalline samples of pure and Y-doped dipolar spin ice Dy2Ti2O7 was investigated at temperatures from nominally 0.3 K to 6 K and in magnetic fiel…
Configuration-Space Location of the Entanglement between Two Subsystems
H. -C. Lin, A. J. Fisher
In this paper we address the question: where in configuration space is the entanglement between two particles located? We present a thought-experiment, equally applicable to discre…
The Application Hosting Environment: Lightweight Middleware for Grid-Based Computational Science
P. V. Coveney, R. S. Saksena, S. J. Zasada +2
Grid computing is distributed computing performed transparently across multiple administrative domains. Grid middleware, which is meant to enable access to grid resources, is curre…
Entanglement in general two-mode continuous-variable states: local approach and mapping to a two-qubit system
H. -C. Lin, A. J. Fisher
We present a new approach to the analysis of entanglement in smooth bipartite continuous-variable states. One or both parties perform projective filterings via preliminary measurem…
Nature of the Magnetic Order in the Charge-Ordered Cuprate LaNdSrCuO
N. B. Christensen, H. M. Ronnow, J. Mesot +7
Using polarized neutron scattering we establish that the magnetic order in LaNdSrCuO is either (i) one dimensionally modulated and collinear, consiste…
Multiple Magnon Modes and Consequences for the Bose-Einstein Condensed Phase in BaCuSi2O6
Ch. Rüegg, D. F. McMorrow, B. Normand +7
The compound BaCuSi2O6 is a quantum magnet with antiferromagnetic dimers of S = 1/2 moments on a quasi-2D square lattice. We have investigated its spin dynamics by inelastic neutro…
Three-dimensionality of field-induced magnetism in a high-temperature superconductor
B. Lake, K. Lefmann, N. B. Christensen +9
Many physical properties of high-temperature (high-Tc) superconductors are two-dimensional phenomena derived from their square planar CuO2 building blocks. This is especially true…
Vibrational inelastic scattering effects in molecular electronics
H. Ness, A. J. Fisher
We describe how to treat the interaction of travelling electrons with localised vibrational modes in nanojunctions. We present a multichannel scattering technique which can be appl…
Quantum Communication in Spin Systems With Long-Range Interactions
M. Avellino, A. J. Fisher, S. Bose
We calculate the fidelity of transmission of a single qubit between distant sites on semi-infinite and finite chains of spins coupled via the magnetic dipole interaction. We show t…
Stress response and structural transitions in sheared gyroidal and lamellar amphiphilic mesophases: lattice-Boltzmann simulations
Nelido Gonzalez-Segredo, Jens Harting, Giovanni Giupponi +1
We report on the stress response of gyroidal and lamellar amphiphilic mesophases to steady shear simulated using a bottom-up lattice-Boltzmann model for amphiphilic fluids and slid…
