Bohmian Time Versus Probabilistic Time

TL;DR

This paper compares Bohmian time and probabilistic time, two approaches to the quantum cosmology problem of time, analyzing their differences and implications within a mini-super space model.

Contribution

It provides a comparative analysis of Bohmian and probabilistic time definitions in quantum cosmology, extending semi-classical time concepts.

Findings

Bohmian and probabilistic times differ in their treatment of quantum cosmological models.

The comparison reveals specific advantages and limitations of each approach.

Results suggest potential directions for integrating these time concepts in quantum gravity.

Abstract

One of the basic peoblems of quantum cosmology is the problem of time. Various solutions have been proposed for this problem. One approach is to use the Bohmian time. Another Approach is to use the probabilistic time which was recently introduced by Castagnino. We consider both of these definitions as generalizations of a semi-classical time and compare them for a mini-super space.
