Definition of the vacuum in curved space-time

  • Published:
Soviet Physics Journal Aims and scope

Abstract

It is proposed that the vacuum state of quantized fields in curved space-time be defined as the state which minimizes the average value of the field Hamiltonian. Starting from this definition, equations are obtained for finding positive- and negative-frequency functions for spinor and scalar fields.
