Strange Metal Hall Effect in Underdoped BaFe(AsP)
Augusto Ghiotto, Darian Hall, Yuanqi Lyu +7
The unusual transport properties of strange metals point to the breakdown of the quasiparticle picture, the understanding of which remains one of the most vexing problems in physic…
Eclipsing Kitaev: off-diagonal exchange governs the correlated high-field phases of -LiIrO
Vikram Nagarajan, Ioannis Rousochatzakis, Yuanqi Lyu +9
We report a high-field thermodynamic study of the hyperhoneycomb Kitaev material -LiIrO, using magnetotropic susceptibility to resolve its low-temperature field-angle ph…
From Knots to Crystals: Machine-Learned Potentials for Self-Assembling Topological Solitons in Liquid Crystals
Arunkumar Bupathy, Darian Hall, Ivan I. Smalyukh +3
Knotted fields in classical and quantum systems have long been recognized for their non-trivial topologies and particle-like behavior, but practical applications have been limited…
Fusion and Fission of Particle-like Chiral Nematic Vortex Knots
Darian Hall, Jung-Shen Benny Tai, Louis H. Kauffman +1
Vortex knots have been seen decaying in many physical systems. Here we describe topologically protected vortex knots, which remain stable and undergo fusion and fission while conse…
Analysis of Hopf solitons as generalized fold maps
Yuta Nozaki, Darian Hall, Ivan I. Smalyukh +1
The Hopf index, a topological invariant that quantifies the linking of preimage fibers, is fundamental to the structure and stability of hopfions. In this work, we propose a new ma…
