Rational magnetic equivariant K-theory
Higinio Serrano, Bernardo Uribe, Miguel A. Xicoténcatl
We introduce the magnetic equivariant K-theory groups as the K-theory groups associated to magnetic groups and their respective magnetic equivariant complex bundles. We restrict th…
Spin Chern number in altermagnets
Rafael Gonzalez-Hernandez, Higinio Serrano, Bernardo Uribe
This work explores the topological properties of altermagnets, a novel class of collinear magnetic materials. We employ equivariant K-theory of magnetic groups and Hamiltonian mode…
Topological Spherical T-duality -- Dimension change from higher degree -flux
Gil R. Cavalcanti, Bart Heemskerk, Bernardo Uribe
Topological Spherical T-duality was introduced by Bouwknegt, Evslin and Mathai in [BEM15] as an extension of topological T-duality from -bundles to -bundles en…
On the average spin Chern number
Rafael Gonzalez-Hernandez, Bernardo Uribe
In this work, we propose the average spin Chern number (ASCN) as an indicator of the topological significance of the spin degree of freedom within insulating materials. Whenever th…
