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…
Quantum Barkhausen Noise Induced by Domain Wall Co-Tunneling
C. Simon, D. M. Silevitch, P. C. E. Stamp +1
Most macroscopic magnetic phenomena (including magnetic hysteresis) are typically understood classically. Here, we examine the dynamics of a uniaxial rare-earth ferromagnet deep wi…
Direct Observation of Collective Electronuclear Modes About a Quantum Critical Point
M. Libersky, R. D. McKenzie, D. M. Silevitch +2
We directly measure the low energy excitation modes of the quantum Ising magnet LiHoF using microwave spectroscopy. Instead of a single electronic mode, we find a set of collec…
A continuous metal-insulator transition driven by spin correlations
Yejun Feng, Yishu Wang, D. M. Silevitch +4
Metal-insulator transitions involve a mix of charge, spin, and structural degrees of freedom, and when strongly-correlated, can underlay the emergence of exotic quantum states. Mot…
