具有PT对称性的非厄米哈密顿算子的实谱

Real Spectra in Non-Hermitian Hamiltonians Having PT Symmetry

Carl M. Bender, Stefan Boettcher

摘要:

自伴性的条件确保了哈密顿算子的特征值是实的并且有界。用较弱的${\cal PT}$对称性条件代替这个条件,得到了新的无穷类复哈密顿量,它们的谱也是实的和正的。这些${\cal PT}$对称理论可以看作是传统理论从实到复相空间的解析延续。本文介绍了这些理论的不寻常的经典和量子性质。

英文摘要:

The condition of self-adjointness ensures that the eigenvalues of a Hamiltonian are real and bounded below. Replacing this condition by the weaker condition of ${\cal PT}$ symmetry, one obtains new infinite classes of complex Hamiltonians whose spectra are also real and positive. These ${\cal PT}$ symmetric theories may be viewed as analytic continuations of conventional theories from real to complex phase space. This paper describes the unusual classical and quantum properties of these theories.
