Abstract

We use simple spectral perturbation theory to show that the positive partial transpose property is stable under bounded perturbations of the Hamiltonian, for equilibrium states in infinite dimensions. The result holds provided the temperature is high enough, or equivalently, provided the perturbation is small enough.

PPT在平衡态的稳定性

我们用简单谱摄动理论证明了在无穷维平衡态的哈密顿量的有界摄动下，正偏转置性质是稳定的。只要温度足够高，或者说，只要扰动足够小，这个结果就成立。
