Negative pressure as a quantum effect in free-streaming in the cosmological background
F. Becattini, D. Roselli
We present a study of energy density and pressure of a free real scalar quantum field after its decoupling from a thermal bath in the spatially flat Friedman-Lemaître-Robertson-Wal…
Thermodynamic equilibrium in relativity: four-temperature, Killing vectors and Lie derivatives
F. Becattini
The main concepts of general relativistic thermodynamics and general relativistic statistical mechanics are reviewed. The main building block of the proper relativistic extension o…
Quantum relativistic fluid at global thermodynamic equilibrium in curved spacetime
F. Becattini, E. Grossi
We present a new approach to the problem of the thermodynamical equilibrium of a quantum relativistic fluid in a curved spacetime in the limit of small curvature. We calculate the…
Quantum corrections to the stress-energy tensor in thermodynamic equilibrium with acceleration
F. Becattini, E. Grossi
We show that the stress-energy tensor has additional terms with respect to the ideal form in states of global thermodynamic equilibrium in flat spacetime with non-vanishing acceler…
Covariant statistical mechanics and the stress-energy tensor
F. Becattini
After recapitulating the covariant formalism of equilibrium statistical mechanics in special relativity and extending it to the case of a non-vanishing spin tensor, we show that th…
The ideal relativistic rotating gas as a perfect fluid with spin
F. Becattini, L. Tinti
We show that the ideal relativistic spinning gas at complete thermodynamical equilibrium is a fluid with a non-vanishing spin density tensor σ_μν. After having obtained the express…
