SOME CONCLUSIONS ABOUT HERMITIAN OPERATORS EXTENDED TO NON-HERMITIAN CASES
摘要
Abstract
This paper extends some well-known conclusions about Hermitian operators in quantum mechanics to the case of non-Hermitian operators.Specifically,(1)it presents the eigenvalue structure of non-Hermitian operators satisfying algebraic equations;(2)for a class of diagonalizable non-Hermitian operators,it clarifies the relationship between commutativi-ty,degenerate subspaces,and block diagonalization,and provides a visual representation;(3)taking the four-site spin-1/2 Heisenberg XXZ chain as an example,it specifically illus-trates the physical implications and applications of these extended results.关键词
