High Energy Theory Seminar - Adam Brown, Stanford University - "Hot Bubbles of Nothing"

PCTS Seminar Room
“Bubbles of nothing” are a dramatic instability of spacetimes with compact extra dimensions. A hole appears in spacetime, inside of which there is neither space nor time: there is literally “nothing”. Witten showed that they may nucleate by quantum tunneling. I will discuss bubbles of nothing that nucleate instead by thermal fluctuation (or by a part-quantum part-thermal hybrid process), and exhibit a high-temperature/low-temperature duality with the nucleation of caged black holes.
