Slave-rotor theory of correlated altermagnets on the Lieb lattice
Vanuildo S. de Carvalho, Hermann Freire, Rodrigo G. Pereira
We investigate the metal-insulator transition driven by the onsite repulsive interaction in an altermagnetic Hubbard model defined on a Lieb lattice. Using the slave-rotor appr…

Edge magnetization and spin transport in an SU(2)-symmetric Kitaev spin liquid
V. S. de Carvalho, H. Freire, E. Miranda +1
We investigate the edge magnetism and the spin transport properties of an SU(2)-symmetric Kitaev spin liquid (KSL) model put forward by Yao and Lee [Phys. Rev. Lett. \textbf{107},…
