Topological phase transitions and Berry-phase hysteresis in exchange-coupled nanomagnets
Ahsan Ullah, Xin Li, Yunlong Jin +6
Topological phase in magnetic materials yields a quantized contribution to the Hall effect known as the topological Hall effect, which is often caused by skyrmions, with each skyrm…

Exceptional points as signatures of dynamical magnetic phase transitions
Kuangyin Deng, Xin Li, Benedetta Flebus
One of the most fascinating and puzzling aspects of non-Hermitian systems is their spectral degeneracies, i.e., exceptional points (EPs), at which both eigenvalues and eigenvectors…
