    Quantum Inequalities from the Second Law

    Andrea Palessandro

    Derives bounds on the magnitude and duration of negative energy in quantum field theory from the second law of thermodynamics using a small thermal detector.

    International Journal of Theoretical Physics 65, 233 · arXiv:2608.11817

    Time as a Cosmological Phenomenon

    Andrea Palessandro

    Argues that the arrow of time arises from the global geometry and topology of the universe, making time’s direction fundamentally cosmological.

    Graviton-photon oscillations as a probe of quantum gravity

    Andrea Palessandro

    Tests whether graviton-to-photon conversion could reveal gravity’s quantization and finds that efficient single-graviton detection would require radically improved low-frequency photon detectors.

    Graviton-photon oscillations in an expanding universe

    Peter Anninos, Tony Rothman, Andrea Palessandro

    Studies graviton–photon mixing in expanding cosmologies and shows that cosmic expansion and charged matter generally damp or freeze the oscillations.

    A simple derivation of the Gertsenshtein effect

    Andrea Palessandro, Tony Rothman

    Provides a direct derivation of the Gertsenshtein effect and explains why strong neutron-star magnetic fields may act as plausible graviton sources.

    Gravitational Absorption Lines

    Andrea Palessandro, Martin S. Sloth

    Proposes gravitational absorption lines as signatures of quantized gravity, exotic bound states, or new Planck-scale gravitational physics.

    Gravitational Atoms

    Niklas G. Nielsen, Andrea Palessandro, Martin S. Sloth

    Explores purely gravitational dark-sector bound states and the gravitational-wave or ultrahigh-energy cosmic-ray signals produced by their decay.

    Charged Planckian Interacting Dark Matter

    Mathias Garny, Andrea Palessandro, McCullen Sandora, Martin S. Sloth

    Extends Planckian Interacting Dark Matter with a hidden U(1) charge, showing how internal thermalization changes its relic abundance and observational signatures.
