Anomalous thermoelectric and thermal Hall effects in irradiated altermagnets
The episode discusses a paper showing that irradiating a d-wave altermagnet with elliptically polarized light can transform it into a Chern insulator. This process generates anomalous thermoelectric and thermal Hall effects, including quantized thermal transport, which serves as a strong signature of the induced topology. The discussion focuses on how controlling light amplitude dictates the topological phase transition.
