Observation geometry for uncertainty-aware Hamiltonian inference and experimental design in quantum magnets
Roy Liu, Venugopal Ranganathan, David Dahlbom +12
Determining microscopic interactions from spectroscopic and scattering measurements is central to understanding quantum materials, yet it often remains unclear which interactions c…
Tunable Skyrmions in a Topological Wigner Crystal
David A. Dahlbom, Daniel Kaplan, Premala Chandra +1
In low density systems with strong interactions electrons are expected to crystallize into a Wigner solid. Recently, advances in two-dimensional systems where electrons carry Berry…
The 6H-Perovskite Dimer Lattice with Antiferromagnetic Interactions: BaARuO
Daniel M. Pajerowski, David A. Dahlbom, Daniel Phelan +2
We investigate the magnetic behavior of the 6H-perovskite dimer lattice BaZnCaRuO using analytical theory, density functional theory, inelastic neutron scat…
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…
Sunny.jl: A Julia Package for Spin Dynamics
David Dahlbom, Hao Zhang, Cole Miles +16
Sunny is a Julia package designed to serve the needs of the quantum magnetism community. It supports the specification of a very broad class of spin models and a diverse suite of n…
Quantum entanglement of XY-type spin dimers in Shastry-Sutherland lattice
Qianli Ma, Brianna R. Billingsley, Madalynn Marshall +8
We report a comprehensive study on the origin of the enigmatic disordered ground state within the Shastry-Sutherland lattice, BaCeZnS, at low temperatures. The magnetizatio…
