Approaching the Inverse Neutron Scattering Problem with Neural Networks
Jingyi Luo, Fletcher Williams, Ang-Kun Wu +3
Determining the microscopic Hamiltonian of a quantum magnet from inelastic neutron scattering measurements remains a central challenge in condensed matter physics. While the dynami…
Skyrmion and Meron Crystals in Intermetallic GdRuAl: Microscopic Model Insights into Chiral Phases
Jiajun Mo, Leandro M. Chinellato, Fletcher Williams +14
Topological spin textures in frustrated intermetallics hold great promise for spintronics applications. However, understanding their origin and properties remains a significant cha…
Skyrmions of Frustrated Quantum Dimer Systems
Fletcher Williams, David Dahlbom, Hao Zhang +3
Magnetic skyrmions are topologically protected solitons observed in various classes of real magnets. In two-dimensional systems, where the target space of local magnetization value…
Emergent Fermion Dynamical Symmetry for Monolayer Graphene in a Strong Magnetic Field
Mike Guidry, Lianao Wu, Fletcher Williams
We review the physics of monolayer graphene in a strong magnetic field, with emphasis on highly collective states that emerge from the weakly interacting system because of correlat…
