A Gallery of Soft Modes: Theory and Experiment at a Ferromagnetic Quantum Phase Transition

P. C. E. Stamp, D. M. Silevitch, M. Libersky +3

We examine the low-energy excitations in the vicinity of the quantum critical point in LiHoF${}_4$, a physical realization of the Transverse Field Ising Model, focusing on the long-r…
