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 initiates the study of spherically symmetric spacetimes in second-order effective gravitational theories by proving the existence of regular Vaidya solutions that describe the dynamical formation and evolution of regular black holes without curvature singularities, demonstrating how modified gravity can facilitate energy transfer between matter and gravitational degrees of freedom to resolve singularities.
This paper derives a new class of stable, second-order spin-2 theories featuring a massless spin-2 particle and two massless scalars by enforcing linearized transverse diffeomorphism invariance on a rank-2 tensor field, utilizing a gauge-invariant Lagrangian approach with Bardeen variables to identify the spectrum and propose a non-linear completion via a dynamical metric.
This paper proposes a quantum simulation using an atom coupled to a bimodal optical cavity to emulate a (2+1)D massive gravity model, enabling the observation of spacetime metric fluctuations through the evolution of a fermion's spin with current technology.
This paper proposes a construction of fiducial observers in the near-extremal black hole throat within JT quantum gravity by extending asymptotic time translations via conformal isometries, which enables the calculation of quantum gravitational wormhole contributions to the thermal atmosphere, yielding a finite thermal entropy and a quantum description of the stretched horizon.
This paper investigates the thermodynamic and optical properties of Einstein-Dyonic-ModMax black holes by incorporating Generalized Uncertainty Principle corrections and plasma effects, revealing that non-linear electrodynamics and quantum gravity modifications lead to stable remnants, frequency-dependent lensing signatures, and rich phase transition structures.
This paper extends the stochastic formalism to interacting inflationary theories by incorporating one-loop quantum field theory corrections into the noise amplitude, demonstrating that the standard noise term is modified by the fractional correction to the power spectrum, a result applied to the three-phase SR-USR-SR scenario relevant for primordial black hole formation.
This paper generalizes spurion analysis to non-invertible fusion algebras, specifically near-group types like Fibonacci and Ising, by introducing a systematic labeling scheme for coupling constants that explains the radiative violation of tree-level selection rules and distinguishes these effects from those arising in lifted group symmetries.
This paper investigates genuine multientropy and dihedral invariants for tripartite pure states, deriving analytical results for Lifshitz groundstates and establishing connections between these multi-invariants, mutual information, logarithmic negativity, and reflected entropies.
This paper demonstrates that critical points between distinct, featureless bosonic atomic insulators in dimensions can host emergent conformally invariant quantum electrodynamics (QED) states, stabilized by lattice symmetries that suppress monopole proliferation, thereby revealing rich physics even in transitions between trivial phases.
This paper demonstrates that spacetime curvature in and black hole backgrounds induces an effective magnetic field and chiral chemical potential for Dirac fermions, driving asymmetric real-time transport and entanglement dynamics confined within inhomogeneous Lieb-Robinson cones that are diagnostic of curvature and horizon effects.
