Debye mass of massless ϕ^4-theory to order g^6 at weak coupling
Rashid Khan
We calculate the Debye mass of massless ϕ^4-theory to order g^6 at weak coupling. The contributions to the Debye mass arise from the hard momentum scale of order T and the soft mom…
Chiral transition in a magnetic field and at finite baryon density
Jens O. Andersen, Rashid Khan
We consider the quark-meson model with two quark flavors in a constant external magnetic field at finite temperature and finite baryon chemical potential . We calculat…
The chiral phase transition and the role of vacuum fluctuations
Jens O. Andersen, Rashid Khan, Lars T. Kyllingstad
We apply optimized perturbation theory to the quark-meson model at finite temperature T and quark chemical potential mu. The effective potential is calculated to one loop both in t…
The chiral phase transition and the role of vacuum fluctuations
Rashid Khan, Lars T. Kyllingstad
We investigate the chiral phase transition in the quark-meson effective model using optimised perturbation theory to one loop. Certain terms in the free energy are frequently omitt…
