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.

Time-resolved digital quantum simulation of cosmological particle creation in a de Sitter-radiation transition

This paper presents a time-resolved digital quantum simulation of cosmological particle creation during a de Sitter-to-radiation transition using a Trotterized approach and a four-qubit encoding, demonstrating consistency with analytic benchmarks in noiseless simulations while highlighting that current NISQ hardware limitations prevent quantitative reconstruction of the particle spectrum.

On the magnetic counterpart of the Uehling correction

This paper investigates the magnetic counterpart of the Uehling correction in QED by calculating vacuum polarization effects around a classical point-like magnet, revealing induced paramagnetic currents, a quantum-level breaking of the symmetry between electric and magnetic dipole fields, and resulting contributions to the hyperfine structure of hydrogen-like atoms.

Tunneling from an oscillating initial state in quantum mechanics

This paper derives a closed-form, analytically computed expression for the tunneling probability current and time-dependent decay rate of general initial states, including coherently-oscillating ones, from a metastable potential well by decomposing them into resonant states within the semiclassical limit.

Pressure-Energy Equations of State of the Nucleon

This work derives pressure-energy equations of state for the nucleon from gravitational form factors and the conservation of the energy-momentum tensor, revealing a fundamental balance between pressure-induced static pressure (associated with condensate depletion and confinement) and traceless dynamic pressure, while simultaneously demonstrating that the same relations also apply to vortices in type-II superconductors and the cosmological constant in the $\Lambda$ CDM model.

Black-Hole Scattering in Einstein-scalar-Gauss-Bonnet: Numerical Relativity Meets Analytics

This paper demonstrates excellent agreement between fully nonlinear numerical simulations and effective-one-body analytic models for binary black hole scattering in Einstein-scalar-Gauss-Bonnet gravity, validating the capture of strong-field scalar-gravitational dynamics and paving the way for semi-analytical waveform templates in modified gravity theories.

Neutrino Flavor Transformation in Collapsing Supermassive Objects

This article examines how the high neutrino fluxes generated during the collapse of supermassive stars undergo flavor transformations via MSW resonances and collective oscillations, whereby, depending on the neutrino mass hierarchy, electron-neutrino fluxes can be exchanged with muon/tau flavors, significantly affecting energy deposition and nucleosynthesis in the outer layers of the star.

Landscape of Spontaneous CP Violation

This article examines the realization of spontaneous CP violation within a supersymmetric theory, demonstrating how this resolves the strong CP problem, generates the CKM phase, and successfully explains the baryon asymmetry of the universe via the Affleck-Dine mechanism, while simultaneously predicting a measurable electric dipole moment for the neutron.

Hierarchical entanglement transitions and hidden area-law sectors in quantum many-body dynamics

This paper reveals a hierarchical entanglement structure in chaotic many-body dynamics where, following local quantum quenches, the full state exhibits a Renyi-index-tuned transition with area-law scaling for $\alpha > 1$ and volume-law scaling for $\alpha \le 1$ , while the linear response is dominated by a low-dimensional Schmidt sector that itself undergoes an area-to-volume-law transition.

Bound states and deconfinement from Romans supergravity with magnetic flux

Using the gauge-gravity duality within Romans supergravity, this paper investigates the spectrum of bound states in a four-dimensional confining field theory with magnetic flux, revealing a zero-temperature deconfinement phase transition and identifying two nearly degenerate, parametrically light scalar particles—one acting as a dilaton—that emerge near the critical flux limit.

Primordial black holes from inflation: on the decoupling between large and small scales

This paper demonstrates that within single-field inflation models, large-scale modes constrained by CMB observations decouple from small-scale enhancements required for primordial black hole production, ensuring that 1-loop back-reaction effects remain unobservable and do not disrupt large-scale predictions.
