Penrose process in magnetized non-Kerr rotating spacetime with anomalous quadrupole moment
We investigate the magnetic Penrose process in the Quevedo-Mashhoon spacetime, immersed in a uniform magnetic field $B$. This metric is a stationary, axisymmetric, asymptotically flat vacuum solution to Einstein's equations with an arbitrary anomalous quadrupole moment ${\cal Q}$. A non-vanishing ${\cal Q}$ significantly modifies the near-horizon geometry, creating a multi-lobe ergoregion. Both ${\cal Q}$ and $B$ strongly influence the negative-energy region, which can extend well beyond the er…

Simulating Mass-Dependent Decoherence in Quantum Computers: Baseline Signatures for Testing Gravity-Induced Collapse
We present a quantum computing simulation study of mass-dependent decoherence models inspired by Penrose's gravity-induced collapse hypothesis. According to objective reduction (OR) theory, quantum superpositions become unstable when the gravitational self-energy difference between branches exceeds a certain threshold, leading to a collapse time $τ\approx \hbar / E_G$. In this work, we implement a mass-dependent dephasing noise channel, $p(m) = 1 - e^{-k m^α}$, within the Qiskit AerSimulator,…

Baryon-baryon, meson-meson, and meson-baryon interactions in nonrelativistic QCD
Van der Waals potentials describing interactions between color-singlet mesons and/or baryons vanish at leading order in potential nonrelativistic quantum chromodynamics (pNRQCD). This result and constraints from Gauss's law are used to prove that weakly-coupled pNRQCD van der Waals potentials in generic non-Abelian gauge theories with only heavy quarks are too weak to form bound states whose color state is a product of color-singlets. Quantum Monte Carlo calculations of four, five, and six quar…

Europe bets on lead-cooled nuclear reactors to decarbonize sea vessels
Switzerland's ABB and Sweden's Blykalla have joined their forces to develop a small lead-cooled nuclear reactor for maritime use.
