DESCRIPTION:While magnetic systems have been extensively studied both from 
 a fundamental physics perspective and as building blocks for a variety of 
 applications\, their topological properties\, however\, remain relatively 
 unexplored due to their inherently dissipative nature. I will start this t
 alk by discussing how the recent introduction of non- Hermitian topologica
 l classifications has opened up opportunities for engineering topological 
 phases in magnetic systems\, and I will present our first proposal of a no
 n-Hermitian topological magnonic system\, i.e.\, a realization of a SSH no
 n-Hermitian model via a one-dimensional spin- torque oscillator array. Fur
 ther\, I will show how magnetic exceptional points can unveil large-amplit
 ude auto-oscillatory regimes in nano-oscillators. Finally\, I will discuss
  the conditions under which magnetic insulating systems can host one of th
 e most striking non-Hermitian phenomena with no Hermitian counterpart\, i.
 e.\, the skin effect\, which underlies the breakdown of the bulk-edge corr
 espondence.\n\nCo-sponsored by: UCCS\n\nSpeaker(s): Benedetta Flebus\, \n\
