论文摘要
在平坦的空间和有限温度下，量子场理论中有两个错误的真空衰减方案。在低温下，衰减是通过周期性欧几里得溶液描述的热辅助隧道（反弹），具有非平凡的时间依赖性。另一方面，在高温下，弹跳是时间无关的，并描述了在潜在障碍物上的田间的热跳跃。我们认为，仅第二种的溶液与假真空衰减有关，该衰减是由在平衡中用热浴的黑洞催化的。该论点适用于宽类的球形黑洞，包括$ d $二维广告/DS-Schwarzschild黑洞和Reissner-Nordström黑洞，远离关键。它不依赖于薄壁近似，并适用于多场标量理论。
In flat space and at finite temperature, there are two regimes of false vacuum decay in quantum field theory. At low temperature, the decay proceeds through thermally-assisted tunneling described by periodic Euclidean solutions -- bounces -- with non-trivial time dependence. On the other hand, at high temperature the bounces are time-independent and describe thermal jumps of the field over the potential barrier. We argue that only solutions of the second type are relevant for false vacuum decay catalyzed by a black hole in equilibrium with thermal bath. The argument applies to a wide class of spherical black holes, including $d$-dimensional AdS/dS-Schwarzschild black holes and Reissner-Nordström black holes sufficiently far from criticality. It does not rely on the thin-wall approximation and applies to multi-field scalar theories.
