Quantum Inequalities from the Second Law
Andrea Palessandro
Quantum field theory allows local violations of the classical energy conditions, such as regions of negative energy density. The Ford-Roman quantum inequalities quantify how negati…
Time as a Cosmological Phenomenon
Andrea Palessandro
We show that the arrow of time is intimately related to the geometry and topology of the whole universe, and is therefore best understood as a cosmological phenomenon.
Infeasibility of Graviton Detection as Cosmic Censorship
Andrea Palessandro
We construct an explicit model of inhomogeneous gravitational collapse leading to a naked singularity in which gravitational absorption is both efficient and observable. We propose…
Graviton-Photon Oscillations as a Probe of Quantum Gravity
Andrea Palessandro
The Gertsenshtein effect could in principle be used to detect a single graviton by firing it through a region filled with a constant magnetic field that enables its conversion to a…
Graviton-Photon Oscillations in an Expanding Universe
Peter Anninos, Tony Rothman, Andrea Palessandro
Through the Gertsenshtein effect, the presence of a large external B-field may allow photons and gravitons to mix in a way that resembles neutrino oscillations and is even more sim…
A Simple Derivation of the Gertsenshtein Effect
Andrea Palessandro, Tony Rothman
As shown by Gertsenshtein in 1961, an external magnetic field can catalyze the mixing of graviton and photon states in a manner analogous to neutrino-flavor oscillations. We first…
Autocatalysis of Graviton Production via the Gertsenshtein Effect for the Yang-Mills Field
Andrea Palessandro, Tony Rothman
As shown by Gertsenshtein in 1961, an external magnetic field can couple electromagnetic to gravitational waves, giving rise to oscillations between them. Viewed as a quantum proce…
