Toward the Classification of Quantum States in the Hawking-Unruh Effect

The behavior of several states is studied from the viewpoint of a uniformly accelerated observer. Finite-particle states and normalizable coherent states in a certain class become indistinguishable from the vacuum state as the observer's time goes to infinity. For unnormalizable states, we give an example which behaves in a different way. *) JSPS.fellow.
