An electron subject to a periodic potential and a constant electric field exhibit oscillatory dynamics, known as Bloch oscillations. Here, the authors demonstrate a magnetic analogue of Bloch oscillations in a ferromagnetic near-Ising chain, where ma

Abstract The temperature dependence of the low-energy magnetic excitations in the spin-triplet superconductor UTe2 was measured via inelastic neutron scattering in the normal and superconducting states. These excitations have a peak instensity at 4 m

Quantum spin liquids have magnetic moments that do not form magnetic order even as the temperature approaches zero, leading to the dominance of quantum fluctuations. Chillal et al. present evidence that the hyper-hyperkagome lattice of PbCuTe2O6 host

Emergent relativistic quasiparticles in Weyl semimetals are the source of exotic electronic properties such as surface Fermi arcs, the anomalous Hall effect and negative magnetoresistance, all observed in real materials. Whereas these phenomena highl

CaFe$_{2}$O$_{4}$ is an $S=5/2$ antiferromagnet exhibiting two magnetic orders which shows regions of coexistence at some temperatures. Using a Green's function formalism, we model neutron scattering data of the spin wave excitations in this material

VI$_{3}$ is a ferromagnet with planar honeycomb sheets of bonded V$^{3+}$ ions held together by van der Waals forces. We apply neutron spectroscopy to measure the two dimensional ($J/J_{c} \approx 17$) magnetic excitations in the ferromagnetic phase,
