Evidence of Pseudogravitational Distortions of the Fermi Surface Geometry in the Antiferromagnetic Metal FeRh
Joseph Sklenar, Soho Shim, Hilal Saglam +6
The confluence between high-energy physics and condensed matter has produced groundbreaking results via unexpected connections between the two traditionally disparate areas. In thi…
Topological Kinetic Crossover in a Nanomagnet Array
Xiaoyu Zhang, Grant Fitez, Shayaan Subzwari +7
Ergodic kinetics, which are critical to equilibrium thermodynamics, can be constrained by a system's topology. We study a model nanomagnetic array in which such constraints visibly…
Unidirectional Magnetoresistance in Antiferromagnet/Heavy-metal bilayers
