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'…
Vacuum polarization in the Schwarzschild black hole with a global monopole
Leonardo G. Barbosa, Victor H. M. Ramos, João Paulo M. Pitelli
We investigate vacuum polarization on the event horizon of a Schwarzschild black hole carrying a global monopole. For a massless scalar field in the Hartle-Hawking state and wi…
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…
