Qcd Pressure and the Trace Anomaly
Exact relations between the QCD thermal pressure and the trace anomaly are derived. These are used, first, to prove the equivalence of the thermodynamic and the hydrodynamic pressure in equilibrium in the presence of the trace anomaly, closing a gap in previous arguments. Second, in the temporal axial gauge a formula is derived which expresses the thermal pressure in terms of a Dyson-resummed t...
متن کاملThe Qcd Trace Anomaly as a Vacuum Effect
(The vacuum is a medium is the message!) We use arguments taken from the electrodynamics of media to deduce the QCD trace anomaly from the expression for the vacuum energy in the presence of an external color magnetic field. Intuitive discussions of phenomena in quantum field theory frequently take the form of describing them as properties of the vacuum. The vacuum, it is then argued, is just l...
متن کاملClassical Trace Anomaly
We seek the analogy of the mathematical form of the alternative form of Einstein's field equations for Lovelock's field equations. We find that the price for this analogy is to accept the existence of the trace anomaly of the energy-momentum tensor even in classical treatments.
متن کاملTrace anomaly driven inflation
This paper investigates Starobinsky's model of inflation driven by the trace anomaly of conformally coupled matter fields. This model does not suffer from the problem of contrived initial conditions that occurs in most models of inflation driven by a scalar field. The universe can be nucleated semi-classically by a cosmological instanton that is much larger than the Planck scale provided there ...
متن کاملQuantum Tunneling and Trace Anomaly
We compute the corrections, using the tunneling formalisim based on a quantum WKB approach, to the Hawking temperature and Bekenstein-Hawking entropy for the Schwarzschild black hole. The results are related to the trace anomaly and are shown to be equivalent to findings inferred from Hawking’s original calculation based on path integrals using zeta function regularization. Finally, exploiting ...
