摘要
Schwarzschild、Schwarzschild-AdS 和 Schwarzschild-de Sitter 解都允许自由作用的离散对合，这些对合与时空的连续对称性对易。直观上，这些对合对应于相应时空的对径映射。与普通 de Sitter 情形类似，这使我们能够通过对与 Hartle-Hawking（或欧几里得）真空相关的模式进行 Mottola-Allen 变换来构造新的真空。这些真空就是这些黑洞的“alpha”真空。典型黑洞的因果结构可能改善 de Sitter alpha 真空所遇到的某些困难。对于 Schwarzschild-AdS 黑洞，混合两个边界 CFT 算符的 Bogoliubov 变换提供了对偶 CFT alpha 态的构造。最后，我们分析了这些真空的热性质。
