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…
Three-dimensional checkerboard spin structure on a breathing pyrochlore lattice
Margarita G. Dronova, Vaclav Petricek, Zachary Morgan +3
The standard approach to realize a spin liquid state is through magnetically frustrated states, relying on ingredients such as the lattice geometry, dimensionality, and magnetic in…
Theory of magnon-polaritons in quantum Ising materials
R. D. Mckenzie, M. Libersky, D. M. Silevitch +1
We present a theory of magnon-polaritons in quantum Ising materials, and develop a formalism describing the coupling between light and matter as an Ising system is tuned through it…
High-pressure control of optical nonlinearity in the polar Weyl semimetal TaAs
Chen Li, Xiang Li, T. Deshpande +6
The transition metal monopnictide family of Weyl semimetals recently has been shown to exhibit anomalously strong second-order optical nonlinearity, which is theoretically attribut…
