Tunneling in Anisotropic Cosmological Models

TL;DR

This paper investigates tunneling rates in anisotropic cosmological models using Euclidean and Hamiltonian methods, revealing that increased anisotropy exponentially decreases tunneling probability.

Contribution

It introduces a comparative analysis of tunneling in anisotropic cosmologies using two different computational approaches.

Findings

Tunneling probability decreases exponentially with anisotropy.

Both Euclidean and Hamiltonian methods yield consistent results.

Anisotropy significantly impacts quantum tunneling in cosmology.

Abstract

Tunneling rate is investigated in homogenous and anisotropic cosmologies. The calculations is done by two methods: Euclidean and Hamiltonian approaches. It is found that the probability decreases exponentialy as anisotropy is increased.
