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 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
The paper studies how quantum vacuum fluctuations and the stress‑energy tensor of a massive scalar field behave in a conical spacetime when various boundary conditions are imposed…
Vacuum polarization in the Schwarzschild black hole with a global monopole
Leonardo G. Barbosa, Victor H. M. Ramos, João Paulo M. Pitelli
The paper calculates the renormalized vacuum expectation value of a massless scalar field on the horizon of a Schwarzschild black hole that carries a global monopole, using a pertu…
Invisible extended Unruh-DeWitt detector
Victor Hugo M. Ramos, João Paulo M. Pitelli, João C. A. Barata
The paper introduces a localized particle detector model based on a massive quantum field with the spatial origin removed and Robin boundary conditions, yielding discrete bound‑sta…
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…
