Hep-Th, or high-energy theoretical physics, explores the fundamental building blocks of our universe and the forces that govern them. Researchers in this field use complex mathematics to understand everything from subatomic particles to the behavior of black holes, often pushing the boundaries of what we know about space and time.

At Gist.Science, we monitor the arXiv repository to ensure you stay ahead of the curve in this rapidly evolving discipline. For every new preprint uploaded to arXiv under this category, our team generates both accessible plain-language overviews and detailed technical summaries, making cutting-edge research understandable regardless of your background.

Below are the latest papers in high-energy theoretical physics, curated to help you navigate the most significant recent discoveries.

Mass-radius relation, moment of inertia, and tidal love numbers of anisotropic neutron stars in f (R,T) gravity

This study investigates the mass-radius relation, moment of inertia, and tidal Love numbers of anisotropic neutron stars within the f(R,T)=R+2βTf(R,T)=R+2\beta T gravity framework using the Horvat anisotropy model, demonstrating that while both anisotropy and the gravity parameter influence physical properties, the former has a dominant effect, ultimately identifying specific configurations that satisfy observational constraints from GW170817 and GW190814.

Spectrum of radiation from global strings and the relic axion density

This paper investigates the spectrum of radiation emitted by global strings to refine predictions for the relic axion density, finding that correcting for self-field effects and utilizing a "soft" exponential spectrum (rather than the "hard" spectra often seen in simulations) significantly alters the estimated axion mass range, potentially pointing to values between 4 and 160 μ\mueV depending on the emission mechanism.

Probing Entanglement and Symmetries in Random States Using a Superconducting Quantum Processor

Using a superconducting quantum processor, researchers experimentally verified that random many-body quantum states generated by ergodic Floquet models exhibit universal entanglement and symmetry properties consistent with Haar-random ensemble predictions, including the Page curve, entanglement asymmetry, and distinct entanglement phases.

A Maximum Entropy Conjecture for Black Hole Mergers

The paper proposes a conjecture that the final state of a binary black hole merger is determined by a thermodynamic principle of entropy maximization, as the entropy of a hypothetical Kerr black hole mapped from the binary's mass and angular momentum peaks at values strikingly close to the numerical relativity-predicted remnant.

Chaos in the near-horizon dynamics of the dyonic AdS4\rm{AdS_4}-Reissner-Nordström black hole

This paper investigates the dynamics of a probe massless particle near the horizon of a dyonic AdS4_4-Reissner-Nordström black hole under a harmonic potential, revealing that the extremal black hole limit exhibits a counteracting regulatory role where it enhances chaos at low energies (violating the Lyapunov bound) but suppresses it at high energies, thereby establishing a direct mapping between black hole thermodynamics and microscopic chaos.
