We review and discuss some recent developments on the unconventional interaction between superconducting systems and the local gravitational field. While it is known that gravitational perturbations (such as gravitational waves) can affect supercondensates and supercurrents dynamics, here we want to focus on the more subtle superfluid back-reaction acting on the surrounding gravitational field, analysing some specific favourable situations. To this end, we will consider suitable quantum macrosystems in a coherent state, immersed in the static weak Earth's gravitational field, investigating possible slight local alterations of the latter not explained in terms of classical physics.

  1. Vortex-reconnection energy bounds in Bose-Einstein-condensed and superfluid dark matter halos

    astro-ph.GA 2026-07 conditional novelty 6.0

    Vortex reconnections in BEC/superfluid dark matter halos produce dark-sector heating at a rate that is secular but sub-virial for relaxed non-interacting soliton cores, with the dominant uncertainty being the true vor...

  2. Vortex-reconnection energy bounds in Bose-Einstein-condensed and superfluid dark matter halos

    astro-ph.GA 2026-07 conditional novelty 5.0

    Vortex reconnections in BEC/superfluid dark-matter cores can transfer at most 0.06–4.5% of the virial energy in 10 Gyr under fiducial assumptions, so they cannot appreciably restructure the core.

  3. Josephson's effect in the Schwarzschild background

    hep-th 2025-10 conditional novelty 5.0

    Josephson dynamics in Schwarzschild spacetime reduce to flat-space laws with redshifted voltages, giving critical currents that scale as α, power as α², and Shapiro steps fixed in asymptotic variables.
