Interaction-mediated Co-existence of Altermagnetism and Topology
Jasmin Bedow, Nitin Kaushal, Marcel Franz
We study an extended Hubbard model on Lieb lattice at electron filling 2 and 4, and demonstrate that the interactions lead to the simultaneous emergence of altermagnetic order and…
Topological Altermagnetic Insulators
Jasmin Bedow, Nitin Kaushal, Marcel Franz
We study the emergence of altermagnetic topological phases stabilized by Ising spin-orbit coupling in a prototypical Lieb lattice model of a correlated altermagnet. Treating the el…
Spontaneous altermagnetism in multi-orbital correlated electron systems
Nitin Kaushal, Adarsh S. Patri, Marcel Franz
Altermagnets have attracted considerable attention in recent years owing to their potential technological applications in spintronics and magnonics. Recently, a new class of sponta…
Altermagnetism in modified Lieb lattice Hubbard model
Nitin Kaushal, Marcel Franz
We study the emergence of altermagnetism from repulsive interactions for electrons on the Lieb lattice as a model of quasi-2D oxychalcogenides with the so-called "anti-CuO" l…
