Kinetic Theory for the Shear Viscosity of Dense Binary Dipolar Fluid Mixtures
Christopher Devik Fjeldstad, Roberto Troncoso, Astrid S. de Wijn
We construct a kinetic theory for the shear viscosity of dense binary fluid mixtures of strongly-interacting dipolar hard spheres. We derive an expression for the pairwise correlat…
Magnon-dislon hybridization in magnetic insulators
Carlos Saji, Nicolas Vidal-Silva, Roberto E. Troncoso
Spin dynamics in ordered magnets with topological lattice defects is investigated. Using fracton--elasticity duality, we develop an effective field theory of magnons coupled to qua…
Caloric Phenomena and Stirling-Cycle Performance in Heisenberg- Kitaev Magnon Systems
Bastian Castorene, Martin HvE Groves, Francisco J. Peña +5
We investigate the Stirling-cycle performance of a Heisenberg--Kitaev magnonic medium with Dzyaloshinskii--Moriya (DM) interactions. Using linear spin-wave theory, we show the DM i…
Antiferromagnetic Pure Spin Current Memdevices
Martin Latorre, Gaspar De la Barrera, Roberto E. Troncoso +1
Spin currents can be generated through various mechanisms, including the piezospintronic effect, which arises when strain or lattice distortions induce a change in the dipolar spin…
Scattering theory of spin waves by lattice dislocation defects
Cristobal Larronde, Ignacio Castro, Alvaro S. Nunez +2
We investigate spin-wave propagation in magnetic insulators in the presence of lattice dislocations. Within a continuum magnetoelastic framework, we show that the strain fields gen…
Quantum geometry, localization, and topological bounds of spin fluctuations
Carlos Saji, Roberto E. Troncoso
We study how topological crystalline defects--dislocations--reshape the real-space quantum geometric tensor and act as tunable sources of quantum geometry. We show that dislocation…
