Ground state and low-lying excitations of the spin-1/2 XXZ model on the kagome lattice at magnetization 1/3
A. Honecker, D. C. Cabra, M. D. Grynberg +5
We study the ground state and low-lying excitations of the S=1/2 XXZ antiferromagnet on the kagome lattice at magnetization one third of the saturation. An exponential number of no…
Bound states in weakly disordered spin ladders
M. Arlego, W. Brenig, D. C. Cabra +3
We study the appearance of bound states in the spin gap of spin-1/2 ladders induced by weak bond disorder. Starting from the strong-coupling limit, i.e., the limit of weakly couple…
The optimal cloning of quantum coherent states is non-Gaussian
N. J. Cerf, O. Krueger, P. Navez +2
We consider the optimal cloning of quantum coherent states with single-clone and joint fidelity as figures of merit. Both optimal fidelities are attained for phase space translatio…
Exchange constants and spin dynamics in Mn12-acetate
A. Honecker, N. Fukushima, B. Normand +2
We have obtained new inelastic neutron scattering (INS) data for the molecular magnet Mn12-acetate which exhibit at least six magnetic peaks in the energy range 5-35 meV. These are…
Thermal transport of the XXZ chain in a magnetic field
F. Heidrich-Meisner, A. Honecker, W. Brenig
We study the heat conduction of the spin-1/2 XXZ chain in finite magnetic fields where magnetothermal effects arise. Due to the integrability of this model, all transport coefficie…
Communication-Aware Processor Allocation for Supercomputers
Michael A. Bender, David P. Bunde, Erik D. Demaine +4
This paper gives processor-allocation algorithms for minimizing the average number of communication hops between the assigned processors for grid architectures, in the presence of…
