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…
Magnetic topological textures in nonorientable surfaces
Carlos Saji, Mario A. Castro, Vagson L. Carvalho-Santos +3
Topological magnetic textures confined to two-dimensional (2D) non-orientable manifolds exhibit behaviors absent in planar systems. We investigate bimerons on Möbius surfaces and s…
Static and Dynamics of Twisted Skyrmion Tubes in Frustrated Magnets
Carlos Saji, Eduardo Saavedra, Vagson L. Carvalho-Santos +2
Stable three-dimensional topological skyrmion structures in frustrated magnets are investigated. The texture exhibits a helicoid pattern along the vertical direction, described by…
