Three-Dimensional Shankar Skyrmions in Frustrated Antiferromagnets
Vladyslav M. Kuchkin, Ricardo Rama-Eiroa, Carlos Saji +2
We formulate a continuum theory for three-dimensional (3D) Shankar skyrmions in frustrated chiral antiferromagnets (AFs) and derive the conditions for metastable finite-size $π_3(S…

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…
