In the canonical quantization of fields on curved space-time, the definition of the vacuum state is of fundamental importance. We consider the definition of vacuum states for scalar and fermion fields on rotating Minkowski and anti-de Sitter space-times. The construction of the vacuum state for a fermion field is much less constrained than for a scalar field. We explore the consequences of this freedom for the definition of rotating thermal states.
