On the interplay between boundary conditions and the Lorentzian Wetterich equation
Claudio Dappiaggi, Filippo Nava, Luca Sinibaldi
In the framework of the functional renormalization group and of the perturbative, algebraic approach to quantum field theory (pAQFT), in [DDPR23] it has been derived a Lorentian ve…
Boundary conditions and infrared divergences
Lissa de Souza Campos, Claudio Dappiaggi, Luca Sinibaldi
We review the procedure to construct quasi-free ground states, for real scalar fields whose dynamics is dictated by the Klein-Gordon equation, on standard static Lorentzian manifol…
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…
