Topology and orbital piezomagnetism in altermagnets

Jörn Venderbos, Drexel

The discovery of altermagnets has revealed intriguing properties of magnetic materials which expose connections with other phenomena. Perhaps the most interesting and consequential connection is that between altermagnetism and topology. This talk will discuss the connection between altermagnetism and topology, in particular from the perspective of minimal miscroscopic models in two dimensions. Special attention will be given to the way in which electronic topology is reflected in orbital piezomagnetism.
