Unified worldline treatment of Yukawa and axial couplings
F. Bastianelli, O. Corradini, J. P. Edwards +2
We provide a worldline representation of the one-loop effective action for a Dirac particle coupled to external scalar, pseudoscalar, vector and axialvector fields. Extending previ…
Pair creation in electric fields
Christian Schubert
Sauter-Schwinger pair creation in electromagnetic fields is a fundamental prediction of QED and one of the motivations for the present efforts in constructing super-strong lasers.…
Worldline master formulas for the dressed electron propagator, part 1: Off-shell amplitudes
Naser Ahmadiniaz, Victor Miguel Banda Guzman, Fiorenzo Bastianelli +3
In the first-quantised worldline approach to quantum field theory, a long-standing problem has been to extend this formalism to amplitudes involving open fermion lines while mainta…
On the low energy limit of one loop photon-graviton amplitudes
F. Bastianelli, O. Corradini, J. M. Davila +1
We present first results of a systematic study of the structure of the low energy limit of the one-loop photon-graviton amplitudes induced by massive scalars and spinors. Our main…
Worldline Approach to QFT on Manifolds with Boundary
F. Bastianelli, O. Corradini, P. A. G. Pisani +1
We use the image charge method to compute the trace of the heat kernel for a scalar field on a flat manifold with boundary, representing the trace by means of a worldline path inte…
Photon-graviton mixing in an electromagnetic field
F. Bastianelli, U. Nucamendi, C. Schubert +1
Einstein-Maxwell theory implies the mixing of photons with gravitons in an external electromagnetic field. This process and its possible observable consequences have been studied a…
