4阶非Hermitian哈密尔顿系统的谱
On the Spectrum of a 4 by 4 Non-Hermitian Hamiltonian
【摘要】 离散的非Hermitian矩阵在物理学应用领域中有着极其重要的作用,本文针对来源于非Hermitian离散量子系统的一个4阶的复三对角矩阵,给出其谱为实谱的必要条件及在一定条件下的充要条件.
【Abstract】 The problem of discrete non-Hermitian plays an important role in the physical Applications,according to a 4 × 4 tridiagonal complex matrix which originated from a nonHermitian discrete quantum system,we consider the necessary and sufficient conditions of the reality of its spectrum under certain conditions.
