Numerical quality factor statistics for SRF cavities with spatially inhomogeneous multilayer coatings modeled by Gaussian random fields
Aaron Gobeyn, Wolfgang Ackermann, Herbert De Gersem
Bulk niobium has long been the material of choice for superconducting radio-frequency applications. An alternative approach is the superconductor-insulator-superconductor multilaye…
Multilayer model for coatings with arbitrary layers for superconducting radio-frequency applications
Aaron Gobeyn, Wolfgang Ackermann, Herbert De Gersem
We extend the multilayer model of \etal{Kubo} for superconductor-insulator-superconductor (SIS) structures in two ways: first, by generalizing it to arbitrary sequences of layers o…
Scalar field theory under Robin boundary conditions: two-point function and energy-momentum tensor
David Dudal, Aaron Gobeyn, Bruno W. Mintz +2
We reconsider four-dimensional scalar field theory in presence of Robin boundary conditions on two parallel plates. These boundary conditions are directly imposed in the path integ…
The Casimir energy with perfect electromagnetic boundary conditions and duality: a field-theoretic approach
David Dudal, Aaron Gobeyn, Thomas Oosthuyse +2
Using functional integral methods, we study the Casimir effect for the case of two infinite parallel plates in the QED vacuum, with (different) perfect electromagnetic boundary con…
