Physical Aspects of Unitary evolution of Bianchi-I Quantum Cosmological Model

Understand

In this work, we study some physical aspects of unitary evolution of Bianchi-I model.

• In particular, we study the behavior of the volume and the scale factor as a function of time for the Bianchi-I universe with ultra-relativistic fluid ($\alpha=1$).
• The expectation value of volume is shown not to hit any singularity.
• We elucidate on the anisotropic nature of the solution and physically interpret the wavefunction as a superposition of collapsing universe and expanding universe mimicking Hartle-Hawking type wavefunction.
