Abstract

It is well known that the Minkowski vacuum is expressed as an entangled state between the left and right Rindler wedges when it is constructed on the Rindler vacuum. We clarify the expression of the Minkowski vacuum extended from the ordinary left and right regions to the entire Minkowski space-time, including the Kasner expanding universe and Kasner shrinking universe. Our result clarifies the structure of the entanglement of the Minkowski vacuum state in a unified manner and makes it possible to give an operator interpretation of the calculation of the two-point correlation functions. We also investigate the two-dimensional case, and clarify that a similar structure appears in the two-point function of the field.
