在早期宇宙中，蒸发的黑洞加热了周围的等离子体，并在黑洞周围产生了一个温度分布，这可能比黑洞本身更重要。作为一个例子，我们演示了如何周围的热等离子体蒸发黑洞可以有效地通过Kibble-Zurek机制产生单极子。在黑洞重新加热宇宙的情况下，超过1500 GeV的再加热温度已经可以导致单极子关闭宇宙。
In the early universe, evaporating black holes heat up the surrounding plasma and create a temperature profile around the black hole that can be more important than the black hole itself. As an example, we demonstrate how the hot plasma surrounding evaporating black holes can efficiently produce monopoles via the Kibble-Zurek mechanism. In the case where black holes reheat the universe, reheat temperatures above∼ 500 GeV can already lead to monopoles overclosing the universe.
