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 proposes that long-baseline atom interferometers like MAGIS and AION can serve as sensitive non-collider probes for supersymmetric hidden sectors by detecting coherent phase oscillations induced by ultralight moduli or hidden scalars, thereby mapping these signals to fundamental parameters of supersymmetric and string-motivated theories.
This paper proposes that a neighboring brane-world could communicate with ours exclusively through gravity by utilizing the Kaluza-Klein tower as a multi-input multi-output channel, where information is encoded in the occupation patterns, phases, and arrival times of massive graviton modes above a specific energy threshold.
This paper utilizes tensor networks to calculate the gauge-invariant entanglement entropy and stabilizer Rényi entropy of the ground state in (1+1)-dimensional SU(2) lattice gauge theory, revealing a critical crossover point where the system transitions from a high-magic regime to a low-magic regime, thereby offering new insights into the interplay between non-stabilizerness and entanglement relevant for quantum simulations.
This paper proves that the strongly coupled large-N Principal Chiral Model in the double-scaling regime exhibits maximal transcendentality to all orders, with its vacuum-energy expansion coefficients forming polynomials in odd zeta values that reveal deeper number-theoretic regularities.
This paper demonstrates that F-theory Grand Unified Theories impose a strict upper bound on the coupling-to-mass ratio of axion-like particles, predicting that no such particle can exist significantly above the QCD axion band in controlled regimes, thereby rendering these theories falsifiable by the discovery of axion-induced cosmic birefringence or similar phenomena.
By replacing the Polyakov quantum sector with the dilaton-coupled FFN anomaly model in a two-dimensional regular black hole, this study demonstrates that late-time evaporation endpoints are strictly constrained to either a finite-radius remnant at or a highly specific soft-null branch with power-law decay , thereby excluding generic exponential or power-law null evaporation scenarios.
This paper investigates supersymmetric BPS branes in supergravity by distinguishing the cone of BPS brane charges from the subcone admitting black-brane attractor solutions, while conjecturing that all integrally charged states in the latter are realized in the spectrum and that the moduli-independent BPS brane cone is dual to the black-brane cone under electric-magnetic pairing.
This paper demonstrates that by transforming the Fock basis, any Hamiltonian can be reinterpreted as a local lattice theory with wave packet propagation, where the system's dispersion relation and integrability are determined by its energy spectrum, offering a potential framework for quantum mereology.
This paper challenges the common assumption that large occupation numbers alone justify a classical field description for identical bosons, demonstrating instead that the validity of such a description depends critically on the quantum state's proximity to a coherent state rather than merely on the magnitude of the occupation number.
This paper utilizes the exactly solvable 't Hooft model to rigorously demonstrate that a PT-symmetric deformation drives meson states to an exceptional point at a precisely calculable confinement-scaled threshold, causing a definitive breakdown of analyticity in the causal response function characterized by a square-root singularity and linear time-domain growth.
