Physical significance of generalized boundary conditions: an Unruh-DeWitt detector viewpoint on
Lissa de Souza Campos, Claudio Dappiaggi, Luca Sinibaldi
On , we construct the two-point correlation functions for the ground and thermal states of a real Klein-Gordon field admitting generalized …
Hidden freedom in the mode expansion on static spacetimes
Lissa de Souza Campos, Claudio Dappiaggi, Luca Sinibaldi
We review the construction of ground states focusing on a real scalar field whose dynamics is ruled by the Klein-Gordon equation on a large class of static spacetimes. As in the an…
Besov Wavefront Set
Claudio Dappiaggi, Paolo Rinaldi, Federico Sclavi
We develop a notion of wavefront set aimed at characterizing in Fourier space the directions along which a distribution behaves or not as an element of a specific Besov space. Subs…
Ground State for the Klein-Gordon field in anti-de Sitter spacetime with dynamical Wentzell boundary conditions
Claudio Dappiaggi, Benito A. Juárez-Aubry, Alessio Marta
We consider a real Klein-Gordon field in the Poincaré patch of -dimensional anti-de Sitter spacetime, PAdS, and impose dynamical boundary condition on the asymptotic…
