The spectrum of massless bosonic and fermionic fluids satisfying the equation of state $p=(\gamma-1)\rho$ is derived using elementary statistical methods. As a limiting case, the Lorentz invariant spectrum of the vacuum ($\gamma=0, p=-\rho$) is deduced. These results are in agreement with our earlier derivation for bosons using thermodynamics and semiclassical considerations.

Eckart heat-flux applicability in $F(\Phi,X)R$ theories and the existence of temperature gradients
Eckart heat flux holds for all timelike scalar configurations in F(Φ,X)R + G theories if and only if F_X ≡ 0, reducing the theory to a Jordan-like subclass of Horndeski.
