Resummed Effective Action in Inhomogeneous External Field at Zero and Finite Temperature
نویسنده
چکیده
The two ways of resumming the effective action for the massless test particles in inhomogeneous external field at zero and finite temperature providing the infrared finite answer are discussed. The case of the massive test particles having a mass which is parametrically small with respect to a scale set by the inhomogeneous external field is briefly considered. To appear in the Proc. Workhsop ”Quantum Field Theoretical Aspects of High Energy Physics” (Kyffhäuser near Bad Frankenhausen, Germany, September 1993) Alexander von Humboldt Fellow

Derivative Expansion of the One-loop Effective Action in Qed
The one-loop effective action in QED at zero and finite temperature is obtained by using the worldline approach. The Feynman rules for the perturbative expansion of the action in the number of derivatives are derived. The general structure of the temperature dependent part of the effective action in an arbitrary external inhomogeneous magnetic field is established. The two-derivative term in th...

In this paper we studied the thermal negativity in a two-qubit XX spin ½ chain model and XXX spin1/2 chain model(isotropic Heisenberg model)spin-1/2 chain subjected to an external magnetic field inz direction. We calculate analytical relation for the thermal negativity for two qubit XX and XXX spinchain models in the external magnetic field. Effects of the magnetic field and temperature on then...

متن کاملExact Effective Action for (1 + 1 Dimensional) Fermions in an Abelian Background at Finite Temperature
In an effort to further understand the structure of effective actions for fermions in an external gauge background at finite temperature, we study the example of 1 + 1 dimensional fermions interacting with an arbitrary Abelian gauge field. We evaluate the effective action exactly at finite temperature. This effective action is non-analytic as is expected at finite temperature. However, contrary...
