Decoherence in QED at finite temperature
نویسنده
چکیده
We consider a wave packet of a charged particle passing through a cavity filled with photons at temperature T and investigate its localization and interference properties. It is shown that the wave packet becomes localized and the interference disappears with an exponential speed after a sufficiently long path through the cavity. PACS numbers:03.65.-w,03.65.Bz,12.20.Ds

QED second order corrections on the speed of light at low temperature
We want to study thermal corrections on the speed of light at low temperature considering temperature dependence of photon vacuum polarization tensor at two-loop level in the standard QED. It is found that the heat bath behaves as a dispersive medium for the propagation of light and reduces its speed proportional to the second order of temperature. Similarities and differences, in light ...
متن کاملNon-Perturbative QED and QCD at Finite Temperature
We present results of numerical solutions of Schwinger-Dyson equations for the finite-temperature quark and electron propagators. It is shown that both strongly coupled QED and QCD undergo a chiral symmetry restoring phase transition as the temperature is increased. We go beyond the bare vertex or “rainbow” approximation by applying the finite-temperature Ward-Takahashi identity to constrain th...
متن کاملQED effective action at finite temperature and density.
The QED effective action at finite temperature and density is calculated to all orders in an external homogeneous and time-independent magnetic field in the weak coupling limit. The free energy, obtained explicitly, exhibit the expected de Haas – van Alphen oscillations. An effective coupling at finite temperature and density is derived in a closed form and is compared with renormalization grou...
متن کاملUltrarelativistic Electron-Positron Plasma
Ultrarelativistic electron-positron plasmas can be produced in high-intensity laser fields and play a role in various astrophysical situations. Their properties can be calculated using QED at finite temperature. Here we will use perturbative QED at finite temperature for calculating various important properties, such as the equation of state, dispersion relations of collective plasma modes of p...
متن کاملShear Viscosity of Hot QED at Finite Density from Kubo Formula
Within the framework of finite temperature field theory this paper discusses the shear viscosity of hot QED plasma through Kubo formula at one-loop skeleton diagram level with a finite chemical potential. The effective widths(damping rates) are introduced to regulate the pinch singularities. The finite chemical potential, which enhances the contributions to the shear viscosity from the electron...
