Orientational interaction and ordering of Cd_4 tetrahedra in a quasicrystal approximant
Woosong Choi, Christopher L. Henley, Marek Mihalkovic
We model the quasicrystal-related structure CaCd, a bcc packing of icosahedral clusters containing tetrahedra which undergo orientational orderings at T<100 K. We use general s…
NMR relaxation in spin ice due to diffusing emergent monopoles
Christopher L. Henley
At low temperatures, spin dynamics in ideal spin ice is due mainly to dilute, thermally excited magnetic monopole excitations. I consider how these will affect the dynamics of a nu…
Ground States of the Classical Antiferromagnet on the Pyrochlore Lattice
Matthew F. Lapa, Christopher L. Henley
We study the classical ground states of the exchange-coupled Heisenberg antiferromagnet on the Pyrochlore lattice, a non-Bravais lattice made of corner-sharing tetrahedra. In parti…
Heisenberg antiferromagnet on Cayley trees: low-energy spectrum and even/odd site imbalance
Hitesh J. Changlani, Shivam Ghosh, Christopher L. Henley +1
To understand the role of local sublattice imbalance in low-energy spectra of s=1/2 quantum antiferromagnets, we study the s=1/2 quantum nearest neighbor Heisenberg antiferromagnet…
