Analysis

This paper investigates the Quark-Gluon Plasma (QGP), a state of matter in the early universe, using non-linear classical background fields (SU(2) Yang-Mills condensates). It explores quark behavior in gluon backgrounds, calculates the thermodynamic pressure, compares continuum and lattice calculations, and analyzes the impact of gravitational waves on the QGP. The research aims to understand the non-perturbative aspects of QGP and its interaction with gravitational waves, contributing to our understanding of the early universe.
Reference

The resulting thermodynamic pressure increases with temperature but exhibits an approximately logarithmic dependence.

Big Bang as a Detonation Wave

Analysis

This paper proposes a novel perspective on the Big Bang, framing it as a detonation wave originating from a quantum vacuum. It tackles the back-reaction problem using conformal invariance and an ideal fluid action. The core idea is that particle creation happens on the light cone, challenging the conventional understanding of simultaneity. The model's requirement for an open universe is a significant constraint.
Reference

Particles are created on the light cone and remain causally connected, with their apparent simultaneity being illusory.
