High entropy alloys are multi-element random alloys with a strong short range disorder. Here, the authors show that their heat carrying lattice waves, while strongly attenuated by the force-constant disorder, propagate until high energy.

While it is widely believed that high-temperature superconductivity in cuprate materials arises from an intertwined interplay between charge and spin fluctuations, the microscopic coupling between charge and spin degrees of freedom still remains a my

The pseudogap state in high-Tc superconducting copper oxides in one of the most mysterious quantum states of matter whose understanding remains a challenge for condensed matter physicists. The authors report a hidden magnetic texture deep in the pseu

BaFe2As2 is a parent compound for iron based superconductors, and this has motivated extensive study of its magnetic and electronics properties. Here, using neutron polarisation analysis, the authors demonstrate the critical importance of spin-orbit

Phonon lifetime is a fundamental parameter of thermal transport however its determination is challenging. Using inelastic neutron scattering and the neutron resonant spin-echo technique, Lory et al. determine the acoustic phonon lifetime in a single

We use polarized inelastic neutron scattering to study the spin-excitation anisotropy in the bilayer iron-based superconductor CaKFe_{4}As_{4} (T_{c}=35 K). In the superconducting state, both odd and even L modulations of spin resonance have been obs
