Pressure to order $g^{8} * l o g (g)$ in $ϕ^{4}$ -theory at weak coupling

Jens O. Andersen, Lars Kyllingstad, Lars E. Leganger

We calculate the pressure of massless $ϕ^{4}$ -theory to order $g^{8} lo g (g)$ at weak coupling. The contributions to the pressure arise from the hard momentum scale of order $T$ and the…

Screened perturbation theory at four loops

Lars Kyllingstad

We study the thermodynamics of massless phi-fourth theory using screened perturbation theory, which is a way to systematically reorganise the perturbative series. The free energy a…

Four-loop screened perturbation theory

Jens O. Andersen, Lars Kyllingstad

We study the thermodynamics of massless phi-fourth theory using screened perturbation theory. In this method, the perturbative expansion is reorganized by adding and subtracting a…
