Description |
This paper uses inelastic neutron scattering in high magnetic field to determine the parameters of the Hamiltonian of Yb2Ti2O7. The results suggest that this material at low temperature may be in a so-called Coulomb liquid phase. I will explain how the experiment extracts the model Hamiltonian parameters, and then explain what signatures could perhaps be measured in future experiments of the quantum Coulomb liquid phase.
