Quasiparticle Breakdown and Spin Hamiltonian of the Frustrated Quantum Pyrochlore $Yb_{2}Ti_{2}O_{7}$ in a Magnetic Field
The frustrated pyrochlore magnet $Yb_{2}Ti_{2}O_{7}$ has the remarkable property that it orders magnetically but has no propagating magnons over wide regions of the Brillouin zone. Here we use inelastic neutron scattering to follow how the spectrum evolves in cubic-axis magnetic fields. At high fiel...
