Non-Hermitian Physics 来自 arXiv.org 喜欢 0 阅读量: 835 作者:Y Ashida,Z Gong,M Ueda 摘要: A review is given on the foundations and applications of non-Hermitian classical and quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra, including Jordan normal ...
An emerging class of non-Hermitian resonances is that of acoustic bound states in the continuum, which are exotic resonances with a theoretically unbounded Q-factor, providing a versatile and powerful means of enhancing acoustic wave–matter interactions. By making use of the properties of active me...
The non-Hermitian physics analysis implies that the results referred to in ref. 8 requires an alternative interpretation: the optical forces alone are insufficient to produce optical crystallization8,54, and additional forces, such as viscosity, are essential. Fig. 3: Prevalence of complex modes ...
The notion of non-Hermitian optics and photonics rooted in quantum mechanics and photonic systems has recently attracted considerable attention ushering in tremendous progress on theoretical foundations and photonic applications, benefiting from the flexibility of photonic platforms. In this review, we first...
Recently, they have become an excellent platform to study non-Hermitian physics and exceptional points by judiciously tailoring modal coupling and gain–loss distribution. Typical configurations include two or more coupled optical resonators, hybrid resonator–scatterer systems, and a single resonator with...
population (e.g., Bacillus subtilis), vortex pinning in superconductors, and stability solutions of hydrodynamical problems discovered by Hatano and Nelson [Phys. Rev. Lett. 77, 5706 (1996)], can be obtained from solutions of the time-dependent Schrödinger equation with a Hermitian Hamiltonian....

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 fr
