Covariant extrinsic curvature expansion of the nonlocal effective action for a massless scalar field on a manifold with boundary
A. Boasso, C. D. Fosco, B. C. Guntsche +1
We study the nonlocal effective action of a massless scalar field defined on a flat manifold with a curved boundary. Using a heat-kernel approach, we derive a covariant expansion o…
Quantum dissipative effects for a real scalar field coupled to a time-dependent Dirichlet surface in d+1 dimensions
B. C. Guntsche, C. D. Fosco
We study the Dynamical Casimir Effect (DCE) for a real scalar field in dimensions, in the presence of a mirror that imposes Dirichlet boundary conditions and undergoes t…
Dynamical Casimir effect in the worldline formulation
C. D. Fosco, B. C. Guntsche
We evaluate the effective action for the Dynamical Casimir Effect (DCE) for a real scalar field in dimensions within the worldline formulation of quantum field theory. The sc…
Quantum dissipative effects for a real scalar field coupled to a dynamical Neumann surface in d+1 dimensions
C. D. Fosco, B. C. Guntsche
We study dissipative effects for a system consisting of a massless real scalar field satisfying Neumann boundary conditions on a space and time-dependent surface, in d+1 dimensions…
