Electric and spin current vortices in altermagnets
Arsen Herasymchuk, Karl Bergson Hallberg, Erik Wegner Hodt +3
Altermagnets constitute a class of collinear magnets with momentum-dependent spin splitting and vanishing net magnetization. Direct observation of the characteristic altermagnetic…

The current response to an electromagnetic field in a Weyl or Dirac semimetal becomes nonlocal due to the chiral anomaly activated by an applied static magnetic field. The nonlocal…
