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

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.
