Ground states of a Klein-Gordon field with Robin boundary conditions in global anti–de Sitter spacetime
Ground states of a Klein-Gordon field with Robin boundary conditions in global anti–de Sitter spacetime
We consider a real, massive scalar field both on the $n$-dimensional anti--de Sitter (${\mathrm{AdS}}_{n}$) spacetime and on its universal cover ${\mathrm{CAdS}}_{n}$. In the second scenario, we extend the recent analysis on ${\mathrm{PAdS}}_{n}$, the Poincar\'e patch of ${\mathrm{AdS}}_{n}$, first determining all admissible boundary conditions of Robin type that can be applied …
