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.
The paper establishes the positivity of a weighted holographic energy for four-dimensional spacetimes with a negative cosmological constant, provided their conformal boundary at infinity is conformally static and possesses either spherical sections or toroidal sections with a compatible spin structure.
This paper establishes the equivalence of three distinct black hole thermodynamic classification schemes—geometric, topological, and complex—by demonstrating that they all fundamentally rely on the number of extremal points in the temperature curve, thereby unifying these frameworks through two connecting dictionaries.
This paper employs a potential reconstruction approach to analytically solve Einstein-dilaton-Maxwell models for Lifshitz-like magnetic black branes, demonstrating that while the null energy condition and the third law of thermodynamics are uncorrelated in specific 5D anisotropic models, the former implies the latter in a 6D model with 2-form and 3-form fields.
This paper presents a systematic construction of exact anisotropic Lifshitz-like black brane solutions in arbitrary spacetime dimensions using two distinct holographic models, demonstrating that while the third law of thermodynamics holds for certain parameter ranges, specific configurations can lead to non-monotonic entropy-temperature relations indicative of phase transitions and potential violations of the law.
This paper investigates the thermal properties of -symmetric scalar field theories with imaginary couplings by introducing a "thermal normal-ordering" scheme to resolve infrared divergences, enabling the computation of free energy and thermal masses via an -expansion that is validated against exact results in two dimensions and extrapolated to higher dimensions.
This paper investigates loop-level Carrollian amplitudes for gauge theory and gravity using the modified Mellin prescription, demonstrating that finite one-loop results maintain tree-level analytic structures, can be expressed via differential operators acting on tree-level amplitudes, exhibit specific logarithmic behaviors in Carroll time, and naturally factorize to allow for an infrared-safe definition.
This paper demonstrates that supersymmetry resolves the limitation of the orthogonal Grassmannian description for conserved current wave function coefficients by introducing a kinematic prefactor that captures the full solution, while also revealing how the formula's positive and negative branches correspond to distinct supersymmetric invariants and flat-space helicity amplitudes.
This paper investigates vertex operator algebras arising from 3d gauge theories with boundaries, demonstrating that those associated with abelian theories are fermionic extensions of -algebras linked to toric hyper-Kähler varieties and explicitly identifying a new fermionic extension of the Bershadsky-Polyakov algebra for the case.
This paper investigates the finite-time transition probability rate of a uniformly accelerating Unruh-DeWitt detector, demonstrating that it comprises time-independent thermal terms and oscillatory non-thermal transient terms, and derives the specific thermalization times required for the non-thermal contributions to become negligible in both small and large acceleration regimes.
This paper establishes a direct link between statistical mechanics and the Atiyah-Singer index theorem by demonstrating that the partition function of the quantum harmonic oscillator acts as a Chern character for a "virtual physical sheaf," thereby revealing spectral asymmetry and topological structure in bosonic quantum systems.
