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'…
When does a sphere fall like a point particle? Quadrupole universality and Weyl-driven hexadecapole deviations in vacuum general relativity
Tiago S. Amancio, Ricardo A. Mosna, Ronaldo S. S. Vieira
We ask when a spinless spherical extended test body in vacuum general relativity moves as its point-particle counterpart. In Newtonian gravity, harmonicity of the external potentia…
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…
Chaotic orbital dynamics of pulsating stars around black holes surrounded by dark matter halos
Tiago S. Amancio, Ricardo A. Mosna, Ronaldo S. S. Vieira
We analyze the orbital dynamics of spherical test bodies in ``black hole surrounded by dark matter halo'' spherically symmetric spacetimes. When the test body pulsates periodically…
Unruh-deWitt detector in impulsive plane wave spacetimes
João Paulo M. Pitelli, Ricardo A. Mosna
We investigate the response function of an inertial Unruh-deWitt detector in an impulsive plane wave spacetime. Through symmetry considerations applied to the Wightman function, we…
