Uniformly accelerated classical sources as limits of Unruh-DeWitt detectors
Gabriel Cozzella, Stephen A. Fulling, André G. S. Landulfo +1
Although the thermal and radiative effects associated with a two-level quantum system undergoing acceleration are now widely understood and accepted, a surprising amount of controv…
Neutrino flavor oscillations without flavor states
Bruno de S. L. Torres, T. Rick Perche, André G. S. Landulfo +1
We analyze the problem of neutrino oscillations via a fermionic particle detector model inspired by the physics of the Fermi theory of weak interactions. The model naturally leads…
Exact Renormalization Group, Entanglement Entropy, and Black Hole Entropy
Joao Lucas Miqueleto, Andre G. S. Landulfo
The study of black hole physics revealed a fundamental connection between thermodynamics, quantum mechanics, and gravity. Today, it is known that black holes are thermodynamical ob…
Traces of the Unruh effect in surface waves
Guilherme B. Barros, Joao P. C. R. Rodrigues, Andre G. S. Landulfo +1
We look for classical traces of the Unruh effect in gravity waves. For this purpose, we start considering a white noise state of gravity waves on the surface of a water basin and c…
Observer dependence of entanglement in "nonrelativistic" quantum mechanics
Matheus H. Zambianco, Andre G. S. Landulfo, George E. A. Matsas
It was recently shown that, in general, the von Neumann spin entropy of fermionic particles is not invariant under Lorentz boosts. We show that an analogous result can be recovered…
Classical and quantum aspects of the radiation emitted by a uniformly accelerated charge: Larmor--Unruh reconciliation and zero-frequency Rindler modes
Andre G. S. Landulfo, Stephen A. Fulling, George E. A. Matsas
The interplay between acceleration and radiation harbors remarkable and surprising consequences. One of the most striking is that the Larmor radiation emitted by a charge can be se…
