Experimentally Probing Non-Hermitian Spectral Transition and Eigenstate Skewness
Jia-Xin Zhong, Jeewoo Kim, Kai Chen +3
Non-Hermitian (NH) systems exhibit intricate spectral topology arising from complex-valued eigenenergies, with positive/negative imaginary parts representing gain/loss. Unlike the…
