Nanometric modulations of the magnetic structure of the element Nd
H. Suriya Arachchige, L. M. DeBeer-Schmitt, L. L. Kish +17
The rare earth neodymium arguably exhibits the most complex magnetic ordering and series of magnetic phase transitions of the elements. Here we report the results of small-angle ne…
Extraction of the interaction parameters for RuCl from neutron data using machine learning
Anjana M. Samarakoon, Pontus Laurell, Christian Balz +6
Single crystal inelastic neutron scattering data contain rich information about the structure and dynamics of a material. Yet the challenge of matching sophisticated theoretical mo…
Divergence of Majorana-Phonon Scattering in Kitaev Quantum Spin Liquid
Haoxiang Li, A. Said, J. Q. Yan +5
Magnetoelastic interaction couples spin and lattice degrees of freedom and plays a key role in thermal transport properties of magnetic insulators. In the Kitaev quantum spin liqui…
The Role of the Third Dimension in Searching Majorana Fermions in -RuCl via Phonons
Sai Mu, Kiranmayi D. Dixit, Xiaoping Wang +12
Understanding phonons in -RuCl is critical to analyze the controversy around the observation of the half-integer thermal quantum Hall effect. While many studies have focused…
Spin dynamics in the skyrmion-host lacunar spinel GaV4S8
G. Pokharel, H. Suriya Arachchige, S. Gao +10
In the lacunar spinel GaV4S8, the interplay of spin, charge, and orbital degrees of freedom produces a rich phase diagram that includes an unusual Neel-type skyrmion phase composed…
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…
Harnessing Interpretable and Unsupervised Machine Learning to Address Big Data from Modern X-ray Diffraction
Jordan Venderley, Michael Matty, Krishnanand Mallayya +14
The information content of crystalline materials becomes astronomical when collective electronic behavior and their fluctuations are taken into account. In the past decade, improve…
Van Hove singularity in the magnon spectrum of the antiferromagnetic quantum honeycomb lattice

Strongly-coupled quantum critical point in an all-in-all-out antiferromagnet
Yishu Wang, T. F. Rosenbaum, A. Palmer +4
Dimensionality and symmetry play deterministic roles in the laws of Nature. They are important tools to characterize and understand quantum phase transitions, especially in the lim…
Unveiling the role of competing fluctuations at an unconventional quantum critical point
L. Poudel, J. M. Lawrence, L. S. Wu +7
Quantum critical points (QCPs) are widely accepted as a source of a diverse set of collective quantum phases of matter. A central question is how the order parameters of phases nea…
Destabilization of magnetic order in a dilute Kitaev spin liquid candidate
