非厄米量子力学（Non-Hermitian quantum mechanics，NHQM）是量子力学标准（厄米）形式主义的一个重要替代方案，能够解决其他困难的问题。第一本书提出这一理论，它是有用的高级研究生和研究人员在物理，化学和工程。NHQM为共振现象的研究提供了强大的数值和分析工具，共振现象可能是自然界中最引人注目的事件之一。对于在传统埃尔米特框架结构内解决方案导致极端困难的问题，它特别有用。NHQM在各种领域都有应用，包括光学，其中折射率是复杂的;量子场论，其中研究哈密顿量的宇称-时间（PT）对称性;原子和分子物理学以及电气工程，其中引入复势以简化数值计算。
Non-Hermitian quantum mechanics (NHQM) is an important alternative to the standard (Hermitian) formalism of quantum mechanics, enabling the solution of otherwise difficult problems. The first book to present this theory, it is useful to advanced graduate students and researchers in physics, chemistry and engineering. NHQM provides powerful numerical and analytical tools for the study of resonance phenomena-perhaps one of the most striking events in nature. It is especially useful for problems whose solutions cause extreme difficulties within the structure of a conventional Hermitian framework. NHQM has applications in a variety of fields, including optics, where the refractive index is complex; quantum field theory, where the parity-time (PT) symmetry properties of the Hamiltonian are investigated; and atomic and molecular physics and electrical engineering, where complex potentials are introduced to simplify numerical calculations.
