Worldline integration of photon amplitudes
Naser Ahmadiniaz, Victor M. Banda Guzmán, James P. Edwards +5
It has been known for many years that methods inspired by string theory, such as the worldline formalism, allow one to write down integral representations that combine large number…
Master formulas for photon amplitudes in a combined constant and plane-wave background field
Christian Schubert, Rashid Shaisultanov
The worldline formalism has previously been used for deriving compact master formulas for the QED - photon amplitudes in vacuum, in a constant field and in a plane-wave field.…
The Amplitude in an External Homogeneous Electromagnetic Field
R. Shaisultanov
Neutrino-photon interactions in the presence of an external homogeneous constant electromagnetic field are studied. The amplitude is calculated in an electromagnetic field of…
Vacuum Polarization in QED with World-Line Methods
W. Dittrich, R. Shaisultanov
Motivated by several recent papers on string-inspired calculations in QED, we here present our own use of world-line techniques in order to calculate the vacuum polarization and ef…
Backreaction in spinor QED and decoherence functional
R. Shaisultanov
Using the Schwinger-Keldysh (closed time path or CTP) and Feynman-Vernon influence functional formalisms we obtain an expression for the influence functional in terms of Bogoliubov…
On the string-inspired approach to QED in external field
R. Shaisultanov
Strassler's formulation of the string-derived Bern-Kosower formalism is extended to consider QED processes in homogeneous constant external field. A compact expression for the cont…
Backreaction in scalar QED, Langevin equation and Decoherence functional
Shaisultanov R
Using the Schwinger-Keldysh (closed time path or CTP) and Feynman-Vernon influence functional formalisms we obtain a Langevin equation for the description of the charged particle c…
