Pions at Finite Temperature from QCD Sum Rules
The temperature corrections to the current algebra Gell-Mann, Oakes, and Renner (GMOR) relation in SU(2)⊗SU(2) are investigated in the framework of QCD sum rules. There are no corrections at leading order in the quark masses. At the next to leading order we find corrections of the form mq T 2, which are small except near the critical temperature. As a by-product we obtain the temperature behavi...
متن کاملMagnetic Screening at Finite Temperature
It is shown that at finite temperature and in the presence of magnetic sources magnetic fields are screened. This is proven within the framework of classical transport theory both for the Abelian and non-Abelian plasmas. Magnetic screening arises in this formalism as a consequence of polarization effects occurring in the plasmas, and it is non-perturbative in the gauge coupling constant. It is ...
متن کاملThermal Pions at Finite Density
The density corrections, in terms of the isospin chemical potential μI , to the mass of the pions are investigated in the framework of the SU(2) low energy effective chiral invariant lagrangian. As a function of temperature and μI = 0, the mass remains quite stable, starting to grow for very high values of T , confirming previous results. However, the dependence for a non-vanishing chemical pot...
متن کاملCasimir effect at finite temperature of charged scalar field in an external magnetic field
The Casimir effect for Dirac as well as for scalar charged particles is influenced by external magnetic fields. It is also influenced by finite temperature. Here we consider the Casimir effect for a charged scalar field under the combined influence of an external magnetic field and finite temperature. The free energy for such a system is computed using Schwinger’s method for the calculation of ...
متن کاملCavity Field Reconstruction at Finite Temperature
We present a scheme to reconstruct the quantum state of a field prepared inside a lossy cavity at finite temperature. Quantum coherences are normally destroyed by the interaction with an environment, but we show that it is possible to recover complete information about the initial state (before interaction with its environment), making possible to reconstruct any s-parametrized quasiprobability...
