A quantum universe-antiuniverse emerging from Thirring's conformal nothingness

Abstract

In this study, the spontaneous emergence of a quantum universe-antiuniverse from zero point (or nothingness) is simulated metaphorically based on Thirring spinor model. To do this, a novel approach was developed to demonstrate how the quantum universe and its anti-universe emerge at the zero-point conformal of the massless Thirring spinor model. The model's phase-space dynamics are characterized by its attractors, and quantified via Boltzmann-Gibbs-Shannon entropy, relative entropy, and the largest Lyapunov exponent. The results were analysed for their cosmological implications with reference to the Coleman-De Luccia instanton, the Hawking-Turok instanton and CPT-symmetric universe models.
