Quantum Hamilton-Jacobi Theory
Marco Roncadelli, L. S. Schulman
Quantum canonical transformations have attracted interest since the beginning of quantum theory. Based on their classical analogues, one would expect them to provide a powerful qua…
Constraints on Large-Scale Magnetic Fields from the Auger Results
Alessandro De Angelis, Massimo Persic, Marco Roncadelli
A recent article from the Pierre Auger Collaboration links the direction of charged cosmic rays to possible extragalactic sites of emission. The correlation of the direction of suc…
Evidence for a new light spin-zero boson from cosmological gamma-ray propagation?
Alessandro De Angelis, Marco Roncadelli, Oriana Mansutti
Recent findings by Imaging Atmospheric Cherenkov Telescopes indicate a large transparency of the Universe to gamma rays, which can be hardly explained within the current models of…
Behind Pvlas
Marco Roncadelli
We offer a detailed review of the physics behind the PVLAS experiment. We also address some laboratory and astrophysical cross-checks for the recent claim concerning a signal consi…
