Corrections to the Unruh Effect from Robin Boundary Conditions in Punctured Minkowski Spacetime

Nickolas P. Botta, João Paulo M. Pitelli, Ricardo A. Mosna

We consider a real massless scalar field in punctured Minkowski spacetime, endowed at the removed origin with the stable one-parameter family of Robin boundary conditions $G(0)-βG'…

Invisible extended Unruh-DeWitt detector

Victor Hugo M. Ramos, João Paulo M. Pitelli, João C. A. Barata

We develop a localized particle detector model formulated as a massive quantum field on Minkowski spacetime with the spatial origin excised. To render the problem well posed at the…

Vacuum fluctuations and the renormalized stress-energy tensor on a cone with arbitrary boundary conditions

João Paulo M. Pitelli, Ricardo A. Mosna, Victor Hugo M. Ramos +1

We analyze the vacuum fluctuations and the stress-energy tensor of a scalar field of mass in a conical spacetime, where the topological singularity at the apex requires boundar…

Unstable mode and the Unruh-DeWitt detector

Bruno S. Felipe, João P. M. Pitelli

We investigate the quantization of a single unstable mode in a real scalar field subject to a Robin boundary condition in (1+1)-dimensional half-Minkowski spacetime. The instabilit…

Quantum detection of boundary conditions

Jefferson Monção da Silva, João Paulo M. Pitelli

The quantum detection of spacetime conicity was investigated in reference [Phys. Lett. B 820, 136482 (2021)] through the analysis of the response function of an Unruh-deWitt detect…

Quantum superposition of boundary condition in

João P. M. Pitelli, Bruno S. Felipe, Claudio Dappiaggi +1

We explore the quantum superposition of boundary conditions in the context of the Poincaré patch of the two-dimensional Anti-de Sitter space (). Focusing on Robin…
