Scalar heat kernel with boundary in the worldline formalism
Fiorenzo Bastianelli, Olindo Corradini, Pablo A. G. Pisani +1
The worldline formalism has in recent years emerged as a powerful tool for the computation of effective actions and heat kernels. However, implementing nontrivial boundary conditio…
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…
One loop photon-graviton mixing in an electromagnetic field: Part 2
F. Bastianelli, U. Nucamendi, C. Schubert +1
In part 1 of this series compact integral representations had been obtained for the one-loop photon-graviton amplitude involving a charged spin 0 or spin 1/2 particle in the loop a…
Scalar Field with Robin Boundary Conditions in the Worldline Formalism
Fiorenzo Bastianelli, Olindo Corradini, Pablo A. G. Pisani
The worldline formalism has been widely used to compute physical quantities in quantum field theory. However, applications of this formalism to quantum fields in the presence of bo…
Path integrals in curved space and the worldline formalism
Fiorenzo Bastianelli
We describe how to construct and compute unambiguously path integrals for particles moving in a curved space, and how these path integrals can be used to calculate Feynman graphs a…
Mode Regularization of the Configuration Space Path Integral for a Particle in Curved Space
Fiorenzo Bastianelli
The proper definition and evaluation of the configuration space path integral for the motion of a particle in curved space is a notoriously tricky problem. We discuss a consistent…
