Raman magnon spectroscopy of local interactions and ground state selection in
Xiang Li, Scott E. Cooper, Ahmed E. Fahmy +7
Competing and coupled spin and charge interactions in quantum materials lead to a variety of ordered states where local configurations preferentially influence the long-range order…

Four-Wave Mixing at peV Energy Scales
C. Simon, D. M. Silevitch, T. F. Rosenbaum
We measure the non-linear magnetic susceptibility of the disordered quantum Ising magnet, \lihofour, and demonstrate four-wave mixing due to coherent (anti-)Stokes Raman…

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, a physical realization of the Transverse Field Ising Model, focusing on the long-r…
