hep-th papers | Gist.Science

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.

Phantom-divide crossing and suppressed structure growth in kinetically braided dark energy with momentum exchange

This paper presents a linearly stable kinetically braided dark energy model with momentum exchange that successfully achieves an upward phantom-divide crossing while simultaneously suppressing cold dark matter structure growth through a reduced effective gravitational coupling, yielding distinct signatures in the matter power spectrum and CMB temperature anisotropies.

A Geometric CPVSM Framework: Dynamical Quark Mass Spurt with Explicit CP Violation in the Standard Mode

This paper proposes a top-down geometric framework within the Standard Model that utilizes dimensionless 2D ratio vectors to derive exact analytical expressions for the CKM matrix and Jarlskog invariant, demonstrating how a "quark mass spurt" near critical boundaries generates sufficient CP violation to explain the cosmological baryon asymmetry while offering a unified geometric description of flavor mixing in both quark and lepton sectors.

A Bound on the Dynamical Love Number

By applying the Schwarz-Pick theorem to the holomorphic self-map properties of the retarded Green's function, this paper establishes a universal bound on the frequency-dependent dynamical Love number for compact objects like neutron stars and black holes, which is saturated by the single-mode model for neutron stars and constrains tidal heating for black holes.

Generation and purification of excited spacetimes using Schwarzian derivative

This paper utilizes the Schwarzian derivative to formulate and solve differential equations that systematically generate, purify, and relate various two-dimensional spacetime subsets exhibiting thermal particle distributions within the framework of quantum field theory in curved spacetime.

Outcomes of Grand Unified Symmetry Breaking

This paper numerically demonstrates that symmetry breaking in Grand Unified models leads to biased domain walls interacting with magnetic monopoles, resulting in novel phenomena like monopole absorption and black hole formation that generate a detectable stochastic gravitational wave background.

Perturbing Gravitational Atoms: Negative Love, Resonant Tides and Shifted Resonances

This paper develops a robust worldline effective field theory framework to model perturbations in gravitational atoms, revealing that spinning bosonic clouds can exhibit parametrically enhanced negative Love numbers and significantly altering binary inspiral dynamics through shifted resonances and competing tidal effects.

Non-Minimally Coupled Chain Inflation at High Scales

This paper demonstrates that introducing non-minimal coupling to gravity in chain inflation models resolves the tension preventing high-energy scale inflation, thereby enabling viable scenarios at $V_*^{1/4} \sim 10^{11}\,\rm{GeV}$ that predict distinct, testable signatures in the stochastic gravitational wave background and spectral index running.

Crystallography, Group Cohomology, and Lieb-Schultz-Mattis Constraints

This paper presents a comprehensive computational study of the mod-2 cohomology for all 230 three-dimensional space groups, providing explicit ring presentations and degree- $\leq 3$ cocycles to establish a framework for identifying Lieb-Schultz-Mattis anomaly candidates via Wyckoff positions and applying these constraints to U(1) quantum spin liquids on the 3D pyrochlore lattice.

Exactly solvable conformal field theories

This paper reviews the bootstrap approach to exactly solvable two-dimensional conformal field theories without extended chiral symmetry, demonstrating how local conformal symmetry and degenerate fields constrain spectra and correlation functions to yield analytic solutions for theories including Liouville, minimal models, and loop CFTs.

Gapless Phases in (2+1)d with Non-Invertible Symmetries

This paper establishes a systematic framework using (3+1)d Dijkgraaf-Witten Symmetry Topological Field Theories and generalized "club sandwich" interfaces to classify and construct gapless phases with non-invertible categorical symmetries, including intrinsically gapless SPTs and symmetry-breaking phases, by extending known phase transitions of smaller symmetries.
