چکیده
In the present work we investigate temperature effects on the spinor and scalar effective QED, in the context of Thermo Field Dynamics. Following Weisskopf's zero-point energy method, the problem of charge renormalization is reexamined and high temperature contributions are extracted from the thermal correction for the Lagrangian densities.

متن کاملVacuum Polarization Effects from Fermion Zero-Point Energy
The influence of an external electromagnetic field on the vacuum structure of a quantized Dirac field is investigated by considering the quantum corrections to classical Maxwell’s Lagrangian density induced by fluctuations of the non-perturbative vacuum. Effective Lagrangian densities for Maxwell’s theory in (3+1) and (2+1) dimensions are derived from the vacuum zero-point energy of the fermion...
متن کاملQED 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 کاملFinite temperature correlation function of two dissipative massive scalar fields: Thermofield approach
The present paper aims at investigating the manner of two dissipative massive scalar fields. Two massive scalar fields that interact with a reservoir were considered and a reservoir was modeled by continuum Klein-Gordon fields. The Lagrangian of the total system was canonically quantized and the dynamics of the system was determined using the Euler-Lagrange equation. Then, the explicit form of the...
متن کاملEeective Lagrangians and Low Energy Photon-photon Scattering Typeset Using Revt E X 1
We investigate the behavior of the photon-photon scattering near the threshold ! = m e , by comparing the exact result with the approximation obtained using the Euler-Heisenberg eeective Lagrangian supplemented with higher-order derivative corrections. We also examine the ! 2 =m 2 e behavior predicted by including one-loop corrections to the Euler-Heisenberg eeective Lagrangian together with th...
