首先，一个non-Hermitian的Hamiltonian的eigenvalue spectrum不一定是real的，甚至是incomplete的。这种情况的...
Hamiltonians having this property need not be Hermitian, but, except when PCT is spontaneously broken, the energy levels of such Hamiltonians are all real and positive! In this talk I examine quantum mechanical and quantum field theoretic systems whose Hamiltonians are non-Hermitian but obey PCT...
但是non-Hermitian Hamiltonian有一些特殊的情况下会有real spectrum，这种Hamiltonian被称作是Quasi-Hermitian...
最值得注意的是,通过光学增益和损耗操纵光子本征态的能力为定制非厄米哈密顿量(non-Hermitian Hamiltonians)提供了一种新的手段,借以研究超越传统凝聚态系统的新的对称范式,这标志着非厄米光子学(non-Hermitian photonics)的诞生。在过去十年中,这些概念的快速发展...
This book presents the Proceedings of the __15th International Conference on Non-Hermitian Hamiltonians in Quantum Physics__, held in Palermo, Italy, from 18 to 23 May 2015. Non-Hermitian operators, and non-Hermitian Hamiltonians in particular, have recently received considerable attention from bot...
We demonstrate the emergence of a topological ordered phase for non-Hermitian systems. Specifically, we elucidate that systems with non-Hermitian two-body interactions show a fractional quantum Hall (FQH) state. The non-Hermitian Hamiltonian is considere
