Semiclassical time variables in a quantum cosmology with a massless scalar field
Description
They calculate explicit expressions of two semiclassical time variables by the WKB approximation and the Ehrenfest principle in a quantum cosmology with a massless background scalar field. Two time variables are compared and confirmed explicitly to be identical when the scale of the Universe is large
