Multitude of exceptional points in van der Waals magnets
Xin Li, Kuangyin Deng, Benedetta Flebus
Several works have recently addressed the emergence of exceptional points (EPs), i.e., spectral singularities of non-Hermitian Hamiltonians, in the long-wavelength dynamics of coup…
Topological magnetic phase transition in Eu-based A-type antiferromagnets
Eliot Heinrich, Thore Posske, Benedetta Flebus
Recently, a colossal magnetoresistance (CMR) was observed in EuCdP -- a compound that does not fit the conventional mixed-valence paradigm. Instead, experimental evidence p…
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…
Non-linear dynamics of the non-Hermitian Su-Schrieffer-Heeger model
Pieter M. Gunnink, Benedetta Flebus, Hilary M. Hurst +1
We numerically determine the robustness of the lasing edge modes in a spin-torque oscillator array that realizes the non-Hermitian Su-Schrieffer-Heeger model. Previous studies foun…
