Quantum Annealing of a Disordered Magnet
J. Brooke, D. Bitko, T. F. Rosenbaum +1
Traditional simulated annealing utilizes thermal fluctuations for convergence in optimization problems. Quantum tunneling provides a different mechanism for moving between states,…
Antiferromagnetic vortex state in a high-temperature superconductor
B. Lake, H. M. Ronnow, N. B. Christensen +10
There is strong evidence that magnetic interactions play a crucial role in the mechanism driving high-temperature superconductivity in cuprate superconductors. To investigate this…
Anisotropic three-dimentional magnetic fluctuations in heavy fermion CeRhIn5
Wei Bao, G. Aeppli, J. W. Lynn +5
CeRhIn5 is a heavy fermion antiferromagnet that orders at 3.8 K. The observation of pressure-induced superconductivity in CeRhIn5 at a very high Tc of 2.1 K for heavy fermion mater…
Spin dynamics of the model 2D quantum antiferromagnet CFTD
H. M. Ronnow, D. F. McMorrow, R. Coldea +7
The magnetic excitation spectrum in the two-dimensional (2D) S=1/2 Heisenberg antiferromagnet copper deuteroformate tetradeuterate (CFTD) has been measured for temperatures up to T…
