New paper: "Nonlocal one-loop form factors of the spectral action with Standard Model content"

We compute the exact quantum corrections to gravity from all known particles — no new physics, no free parameters, no extra dimensions.

Most quantum gravity frameworks predict nothing testable below the Planck scale.

We derived a parameter-free modification of Newton's potential from the Standard Model particle content alone.

Thermodynamic Topology of 4D Charged AdS Black Holes with $F^{αβ}F^{γλ}R_{αγβλ}$ Coupling We investigate the thermodynamic phase transitions of a four-dimensional charged anti-de Sitter black hole endowed with a non-minimal coupling of the form $F^{αβ}F^{γλ}R_{αγβλ}$. Using perturbative methods, we derive a consistent black hole solution and analyze its thermodynamics through both conventional equilibrium techniques and a topological defect classification approach. The system displays van der Waals-like critical behavior, with a swallow-tail structure in the free energy and distinct phase branches. The topological analysis independently confirms the existence of critical points and classifies the system within the universal topological scheme for black hole thermodynamics.

Just discovered a hep-th article on #arXiv that is very likely AI-generated.
The items in bibliography are basically made-up.

⚛️🧪 We compared a mixed state and a pure entangled Bell state. The mixed state is invariant under rotations. But for the entangled state, quantum correlations couple the phases, breaking that radial symmetry.

New issue: Hawking's Final Theory | BBC Science Focus Magazine Stephen Hawking spent much of his life pulling at a thread, one that had been swallowed by a black hole. He was interested in what happened to material once it passed a black hole’s event horizon – the point of no return, where gravity crushes anything that crosses it into an infinitesimally small point in space. Other theories hypothesise that if you fell in, your atoms would become part of this cosmic monster and reside there until the end of time. Hawking’s maths suggested something else, however. According to his calculations, black holes don’t last until the end of time. In fact, quantum mechanics suggests that a black hole would, over time, fizz away. Its particles would evaporate over aeons until a final, massive burst of energy. Why does this matter? Well, until this point, the prevailing idea in physics was that nothing is ever really destroyed. If we could somehow fish your atoms out of a black hole, and invent a machine that knew where to put them (like your pattern caught in a transporter buffer), we could, in theory, rebuild you. The death of a black hole, and the ultimate end of everything within it, seemed to violate this rule. Hawking had spotted a crack in our model of the Universe. The resolution to this problem that he settled on, after many intellectual battles with other theoretical physicists, was the ‘holographic principle’ (an idea first proposed by physicists Gerard ‘t Hooft and Leonard Susskind). It’s a headscratcher of an idea that suggests the Universe is actually a projection. In this issue, Thomas Hertog, one of Hawking’s closest science collaborators, takes a closer look at this idea. He thinks that we’re close to a discovery that will let us see Hawking’s maths play out in the real world. A discovery that could finally move us closer to a single, unified theory of everything.
