Stabilization of Chromomagnetic Fields at High Temperature?
David Persson
It is well known that a tachyonic mode appears in the spectrum of Yang--Mills theory with a static uniform magnetic field, and that the free energy has an (unstable) minimum at fin…
Stability of large scale chromomagnetic fields in the early universe
Per Elmfors, David Persson
It is well known that Yang-Mills theory in vacuum has a perturbative instability to spontaneously form a large scale magnetic field (the Savvidy mechanism) and that a constant fiel…
Thermal Phase Transition in Weakly Interacting Large N_C QCD
Joakim Hallin, David Persson
We consider thermal QCD in the large N_C limit, mainly in 1+1 dimensions. The gauge coupling is only taken into account to minimal order, by projection onto colour singlets. An exp…
Asymptotic Freedom from Thermal and Vacuum Magnetization
David Persson
We calculate the effective Lagrangian for a magnetic field in spinor, scalar and vector QED. Connections are then made to Yang--Mills theory and QCD. The magnetization an…
Electron Thermal Self-Energy in a Magnetic Field
David Persson
Using the general form of the static energy solutions to the Dirac equation with a magnetic field, we calculate a general self-energy matrix in the Furry-picture. In the limit of h…
Thermal Fermionic Dispersion Relations in a Magnetic Field
Per Elmfors, David Persson, Bo-Sture Skagerstam
The thermal self-energy of an electron in a static uniform magnetic field is calculated to first order in the fine structure constant and to all orders in . We use two…
Thermal Versus Vacuum Magnetization in QED
Per Elmfors, Per Liljenberg, David Persson +1
The magnetized relativistic Fermi and Bose gases are studied at finite temperature and density.In the case of the Fermi gas, the contribution to the magnetization from the vacuum b…
Real-Time Thermal Propagators and the QED Effective Action for an External Magnetic Field
P. Elmfors, D. Persson, B. -S. Skagerstam
The thermal averaged real-time propagator of a Dirac fermion in a static uniform magnetic field is derived. At non-zero chemical potential and temperature we find explicitly th…
