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…
Neel order, ring exchange and charge fluctuations in the half-filled Hubbard model
J. -Y. P. Delannoy, M. J. P. Gingras, P. C. W. Holdsworth +1
We investigate the ground state properties of the two dimensional half-filled one band Hubbard model in the strong (large-U) to intermediate coupling limit ({\it i.e.} away from th…
Quantum kagome antiferromagnet in a magnetic field: Low-lying non-magnetic excitations versus valence-bond crystal order
D. C. Cabra, M. D. Grynberg, P. C. W. Holdsworth +5
We study the ground state properties of a quantum antiferromagnet on the kagome lattice in the presence of a magnetic field, paying particular attention to the stability of the pla…
Intermittency and non-Gaussian fluctuations of the global energy transfer in fully developed turbulence
B. Portelli, P. C. W. Holdsworth, J. -F. Pinton
We address the experimentally observed non-Gaussian fluctuations for the energy injected into a closed turbulent flow at fixed Reynolds number. We propose that the power fluctuatio…
From classical to quantum Kagome antiferromagnet in a magnetic field
D. C. Cabra, M. D. Grynberg, P. C. W. Holdsworth +1
We study the magnetic properties of the Kagome antiferromagnet going from the classical limit to the deep quantum regime of spin 1/2 systems. In all the cases there are special val…
