On the Casimir effect with mixed dynamical edge mode and perfect electromagnetic conducting boundary conditions
Jarne Devroe, David Dudal, Sebbe Stouten
We study the Casimir effect for a parallel plate setup with one plate with dynamical edge mode (DEM) boundary conditions, and one plate with perfect electromagnetic conductor (PEMC…
Non-perturbative corrections to the Casimir energy for a scalar field theory with non-linear boundary conditions
Fabrizio Canfora, David Dudal, Thomas Oosthuyse +3
We consider the case of a free real massive bulk scalar in D=4 dimensions, and embed two parallel plates as interfaces on which we impose non-linear boundary conditions, either Dir…
Uncertainty Quantification of the Fresh-Saltwater Interface from Time-Domain Electromagnetic Data
Arsalan Ahmed, Thomas Hermans, David Dudal +1
Geophysical methods provide a cost-effective way to characterize the subsurface for hydrogeological projects, but they rely on solving an inverse problem. Traditionally, determinis…
Non-Abelian Casimir energy in the Curci-Ferrari model through a functional approach
David Dudal, Philipe De Fabritiis, Sebbe Stouten
Using functional integral methods, we investigate the non-Abelian Casimir energy in the Curci-Ferrari model, which offers an effective description of the infrared regime of Yang-Mi…
A Novel Interpolation-Based Method for Solving the One-Dimensional Wave Equation on a Domain with a Moving Boundary
Michiel Lassuyt, Emma Vancayseele, Wouter Deleersnyder +3
We revisit the problem of solving the one-dimensional wave equation on a domain with moving boundary. In J. Math. Phys. 11, 2679 (1970), Moore introduced an interesting method to d…
Dynamical edge modes in Maxwell theory from a BRST perspective, with an application to the Casimir energy
Fabrizio Canfora, David Dudal, Thomas Oosthuyse +2
Recently, dynamical edge modes (DEM) in Maxwell theory have been constructed using a specific local boundary condition on the horizon. We discuss how to enforce this boundary condi…
