Quantum order by disorder and accidental soft mode Er2Ti2O7
M. E. Zhitomirsky, M. V. Gvozdikova, P. C. W. Holdsworth +1
Motivated by recent neutron scattering experiments, we derive and study an effective "pseudo-dipolar" spin-1/2 model for the XY pyrochlore antiferromagnet Er2Ti2O7. While a bond-de…
Topological Sector Fluctuations and Curie Law Crossover in Spin Ice
Ludovic D. C. Jaubert, Mark J. Harris, Tom Fennell +3
At low temperatures, a spin ice enters a Coulomb phase - a state with algebraic correlations and topologically constrained spin configurations. In Ho2Ti2O7, we have observed experi…
Spin-wave analysis of the transverse-field Ising model on the checkerboard lattice
Louis-Paul Henry, Peter C. W. Holdsworth, Frédéric Mila +1
The ground state properties of the S=1/2 transverse-field Ising model on the checkerboard lattice are studied using linear spin wave theory. We consider the general case of differe…
