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 extends the semiclassical study of the two-component massless Gross-Neveu model to finite temperature, constructing its full large-N phase diagram with inhomogeneous phases via stability analyses and identifying a qualitative change in the diagram at a critical filling fraction.
This paper demonstrates that current cosmological data do not generically exclude light sterile neutrinos but instead strongly disfavor fully thermalized scenarios, leaving partially populated or suppressed-abundance models viable depending on their specific production history and phase-space distribution.
By performing explicit bulk reconstructions in near-horizon modified AdS and BTZ black hole backgrounds, this paper demonstrates that extending the AdS/CFT dictionary to finite induces non-perturbative bulk micro-causality violations characterized by a throat-dependent non-locality scale and a dip-ramp-plateau structure in the spectral form factor.
The paper challenges the view that cosmology reveals a unique underlying reality, arguing instead that its objective content lies in cross-representational informational invariants, thereby redefining scientific progress as the refinement of accessible observational structure rather than convergence toward a fixed ontology.
This paper provides quantitative analytical and numerical evidence from Type IIB Calabi-Yau compactifications that the proposed quantum gravity cutoff bound, , holds for both and axions even near the boundaries of the Kähler moduli space, thereby supporting its status as a general feature of extra-dimensional axions in quantum gravity.
This paper demonstrates that Krylov complexity for single-trace operators dual to open strings on giant gravitons in SYM is governed by integrable, band-limited dynamics in protected sectors, thereby failing to exhibit the proposed universality of complexity growth and motivating a new finite-density framework to test whether leading complexity growth depends solely on coarse thermodynamic data rather than microscopic probe structure.
This review examines recent DESI measurements suggesting a departure from the standard CDM model toward dynamical dark energy, exploring how different parametrizations and datasets influence this preference while analyzing how various beyond-CDM scenarios could explain these findings and potentially resolve existing cosmological tensions.
This paper investigates the resurgent structure of short-time heat kernel asymptotics on real analytic Riemannian manifolds by formulating an infinite-dimensional Picard-Lefschetz framework that connects alien operators to complex geodesic data, a proposal which is validated through a test case on the hyperbolic plane.
This paper proposes a discrete warped Chern-Simons gravity framework for three-dimensional warped AdS holography, demonstrating that boundary monodromies derived from ordered link holonomies serve as fundamental gauge-invariant observables that characterize physical sectors and reproduce warped black hole entropy and WCFT structures in the continuum limit.
This paper employs numerical minimization of the lattice action in trace-deformed Yang-Mills theory on a twisted to demonstrate how fractional instantons, monopole-instantons, and center vortices morph into one another as geometric parameters vary, revealing that the analytic picture of flux collimation holds in pure Yang-Mills theory under specific shape conditions and that transitions between configurations can be discontinuous.
