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 rigorously derives a variational action principle for classical initial value problems by taking the classical limit of the Schwinger-Keldysh formalism, revealing that both forward and backward paths possess classical solutions and fluctuations, with the backward path uniquely propagating backwards in time to naturally enforce zero deviation without manual constraint.
This paper analyzes radiative corrections in no-scale supergravity inflation models, demonstrating that while such corrections can destabilize predictions in certain Wess-Zumino scenarios, specific classes like the Cecotti model maintain small loop effects that preserve agreement with Planck CMB data.
This paper derives exact analytical expressions for the transition of a two-level quantum system from an initial linear superposition of eigenstates to a definite eigenstate under a delta-function pulse, demonstrating that specific interaction strengths can induce an abrupt, measurement-like "collapse" of the wavefunction that is independent of the system's energy gap.
This paper proposes a framework for testing quantum gravity by analyzing the stochastic gravitational-wave background from evaporating near-Planck-mass primordial black holes, demonstrating that their unthermalized graviton spectra preserve distinct signatures of modified temperature-mass relations that can be used to discriminate between various beyond-semiclassical theories.
This paper rigorously reformulates the effective radial dynamics of extremal black holes in Maxwell-Einstein-scalar theories within the Routhian formalism, elucidating the interplay between the Ferrara-Gibbons-Kallosh potential, Sen's entropy functional, and the effective Routhian to determine black hole entropies through their critical values at the event horizon.
This paper demonstrates that symmetry-twisted partition functions computed via the tensor renormalization group framework effectively detect spontaneous symmetry breaking in three-dimensional models, determine the BKT transition in two dimensions, and successfully identify phase transitions in generalized two-dimensional models.
This paper demonstrates that in -gauged gravity, the antisymmetric gauge field induces space-time torsion which modifies the Friedmann equations to produce de Sitter-like cosmic acceleration and an effective equation-of-state parameter of without requiring exotic matter.
This paper introduces a novel generative architecture based on physics-informed kernels that resolves sign problems and enables efficient sampling for systems with complex probability distributions by mapping them to sign-problem-free manifolds, demonstrating its effectiveness in zero-dimensional field theories and real-time quantum-mechanical evolution.
This paper derives exact, convergent representations for multiloop sunset Feynman integrals in two dimensions with arbitrary masses and all loop orders, utilizing symmetric polynomials and dimension-raising relations to facilitate high-precision numerical evaluation and the systematic reconstruction of four-dimensional results.
This paper demonstrates that in a class of "ultra slow-turn" multi-field inflation models, an exponentially decreasing turn rate can stabilize tachyonic isocurvature perturbations, allowing the total entropy perturbation to correctly assess stability even when the effective mass squared is negative.
