title:
Bunch–Davies vacuum
text:
In quantum field theory in curved spacetime, there is a whole class of quantum states over a background de Sitter space which are invariant under all the isometries: the alpha-vacua. Among them there is a particular one whose associated Green functions verify a condition consisting to behave on the light-cone as in flat space. This state is usually called the Bunch–Davies vacuum or Euclidean vacuum,
actually was first obtained by N.A. Chernikov and E. A. Tagirov, in 1968 and later by C. Schomblo
