Spin decoherence by spacetime curvature
Hiroaki Terashima, Masahito Ueda
abstract: A decoherence mechanism caused by spacetime curvature is discussed. The spin
state of a particle is shown to decohere if only the particle moves in a curved
spacetime. In particular, when a particle is near the event horizon of a black
hole, an extremely rapid spin decoherence occurs for an observer who is static
in a Killing time, however slow the particle's motion is.
