To be specific, we first prove that the non-degenerate steady state of a non-Hermitian quantum many body system is a universal function of the first derivative of the steady state energy with respect to the control parameter. This finding has far-reaching consequences for non-Hermitian systems....
194Citations 5Altmetric Metrics Abstract Non-Hermitian theory is a theoretical framework used to describe open systems. It offers a powerful tool in the characterization of both the intrinsic degrees of freedom of a system and the interactions with the external environment. The non-Hermitian framework...

Thus, the non-Hermitian approach to disorder-induced control of propagation time, wave-front shape and transmitted intensity proposed in this paper opens new possibilities for ultrafast (picosecond or subnanosecond) multifunctional manipulation of optical signals. Results Problem statement Hereinafter, we ...
A key innovation of our approach lies in the precise control over the refractive index with the application of variable magnetic fields, enabling adjustments spanning from positive through zero to significantly negative values, as well as the on-off switchability of NRI phenomena. This breakthrough ...
