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.
This paper introduces a reinforcement learning algorithm to explore the holographic entropy cone by searching for graph realizations of target entropy vectors, successfully rediscovering known properties for N=3 and resolving the status of six "mystery" extreme rays for N=6 by proving three are realizable while suggesting the other three reveal unknown holographic inequalities.
This paper establishes a phase-resolved field-space distance budget for non-inflationary cosmologies, deriving new constraints on ekpyrotic and bouncing models by integrating anisotropy suppression, quantum gravity-inspired cutoffs, and observational limits to demonstrate that achieving scale-invariant perturbations with a red tilt necessitates ultra-fast-roll dynamics, sharp turns, or significant negative field-space curvature.
This paper introduces and analyzes a solvable model of 3d quantum gravity defined by summing copies of a rational Virasoro TQFT over all 3d topologies, demonstrating its holographic duality to an ensemble of 2d CFTs and showing that in the large central charge limit, the model reproduces key semiclassical features such as a positive density of states, a Hawking-Page transition, and suppressed wormhole amplitudes.
This study utilizes Ruppeiner thermodynamic geometry in the grand canonical ensemble to demonstrate that quintessence-adorned Reissner-Nordström Anti-de Sitter black holes exhibit a unique transition from dominant attractive to repulsive microscopic interactions as electric potential increases, while maintaining constant interaction strength during phase transitions.
This paper investigates the collision dynamics of false-vacuum oscillons in two -dimensional scalar field theories, revealing that their interactions exhibit phase-dependent exponential forces, resonance windows, and, in normal theories with sufficient energy, a transition to true vacuum via kink-antikink pair formation.
This paper formulates out-of-equilibrium jet momentum broadening in QCD effective kinetic theory using a moment expansion to explicitly derive a leading-order correction to the spatial broadening tensor controlled by the medium's shear-stress tensor, thereby establishing a direct link between kinetic theory and event-by-event viscous hydrodynamic simulations for heavy-ion collisions.
This paper derives gravitational waveforms for charged compact binaries in Einstein-scalar-Maxwell theories, demonstrating how scalar and vector charges induce dipole radiation and phase modifications characterized by a single parameter , which is constrained by binary pulsar observations and applicable to black hole, neutron star, and exotic compact object systems.
The paper proposes a novel method to detect asteroid-mass Primordial Black Hole dark matter by observing a unique "gravitational spectral radio forest"—a symmetric splitting of the hydrogen 2P3/2 state into a 2 GHz bandwidth caused by tidal spacetime curvature in H II regions.
This paper reviews a novel conformal bootstrap framework that replaces traditional positivity constraints with dispersion relations and neural networks to analyze scalar thermal two-point functions, demonstrating its numerical stability and application to Generalized Free Fields and 4d holographic CFTs.
This study demonstrates that the transmission signal in traversable wormhole protocols using coupled SYK systems depends solely on inter-system coupling rather than quantum chaos, revealing that 98% of Hamiltonian terms can be removed to drastically reduce experimental gate counts while preserving the signal's integrity.
