To efficiently capture the energy of the nuclear bond, advanced nuclear reactor concepts
seek solid fuels that must withstand unprecedented temperature and radiation extremes. In …

The Kitaev quantum spin liquid (KQSL) is an exotic emergent state of matter exhibiting
Majorana fermion and gauge flux excitations. The magnetic insulator α-RuCl3 is thought to …

The first eight years of operation of the Cold Neutron Chopper Spectrometer (CNCS) at the
Spallation Neutron Source in Oak Ridge is being reviewed. The instrument has been part of …

Recent work on superionic conductors has demonstrated the influence of lattice dynamics
and the softness of the lattice on ionic transport. When examining either the changes in the …

The broken symmetry in the atomic-scale ordering of glassy versus crystalline solids leads to
a daunting challenge to provide suitable metrics for describing the order within disorder …

Lanthanides in the trivalent oxidation state are typically described using an ionic picture that
leads to localized magnetic moments. The hierarchical energy scales associated with …

Using neutron scattering and ab initio simulations, we document the discovery of a new
“quantum tunneling state” of the water molecule confined in 5 Å channels in the mineral …

The anharmonic phonon properties of SnSe in the P nma phase were investigated with a
combination of experiments and first-principles simulations. Using inelastic neutron …

We characterize the suitability of two additive manufactured materials for use in shielding
thermal neutrons for neutron scattering instrumentation. We compare two different boron …

Crystalline solids exhibiting glass-like thermal conductivity have attracted substantial
attention both for fundamental interest and applications such as thermoelectrics. In most …
