Inward dispersion of the spin excitation spectrum of stripe-ordered La2NiO4+d
P. G. Freeman, S. M. Hayden, C. D. Frost +5
Polarized- and unpolarized-neutron scattering measurements of the spin excitation spectrum in the stripe-ordered phase of La2NiO4+d (d = 0.11) are presented. At low energies, the m…

Magnetic Excitations in the High Tc Iron Pnictides
Dao-Xin Yao, Erica W. Carlson
We calculate the expected finite frequency neutron scattering intensity based on the two-sublattice collinear antiferromagnet found by recent neutron scattering experiments as well…

Quantum phase transitions beyond the dilute Bose gas limit
Valeri N. Kotov, D. X. Yao, A. H. Castro Neto +1
We study a Heisenberg S=1/2 ring-exchange antiferromagnet which exhibits a quantum phase transition from a spontaneously dimerized (valence bond solid) phase to a magnetically orde…
