Abstract |
We consider thermal states of Dirac particles as seen by an observer rotating with a constant angular velocity about a fixed axis. Our analytic results show that the energy density in thermal states diverges as an inverse power of the distance from the speed of light surface, i.e. the surface at which co-rotating particles move with the speed of light. Enclosing the system in a cylindrical box inside or on the speed of light surface cures this divergence, but brings about the Casimir divergece. An asymptotic analysis of our implementation of the MIT bag model shows that the renormalised vacuum expectation value of the energy density diverges as an inverse power of the distance from the bounding surface. |
