Grading the Unspoken: Evaluating Tacit Reasoning in Quantum Field Theory and String Theory with LLMs

This paper introduces a five-level expert-curated evaluation framework to demonstrate that while large language models excel at explicit derivations in quantum field theory and string theory, they systematically fail when tasks require reconstructing tacit reasoning or maintaining global conceptual consistency, thereby revealing the limitations of current evaluation paradigms for highly abstract theoretical physics.

On Computational CUDA Studies of Black Hole Shadows

This paper utilizes high-performance CUDA simulations combined with the Hamilton–Jacobi formalism to investigate the shadows and energy emission rates of rotating charged Euler–Heisenberg black holes with global monopoles, revealing that while the global monopole, electric charge, and rotation parameters significantly influence these properties, the Euler–Heisenberg nonlinear parameter has a negligible effect, thereby enabling the establishment of strict bounds on the former parameters to reconcile with Event Horizon Telescope observations.

Electromagnetic, gravitational wave, and static gravitational transmission through throat spacetimes: a constraint-wave asymmetry

This paper demonstrates a universal constraint-wave asymmetry in static, spherically symmetric throat spacetimes, where propagating electromagnetic and gravitational waves ($\ell \ge 1$) experience strong sub-barrier suppression due to effective potential barriers, whereas static gravitational monopole perturbations ($\ell = 0$) undergo only polynomial attenuation without such barriers.

Magic and Non-Clifford Gates in Topological Quantum Field Theory

This paper demonstrates that non-Clifford gates essential for universal quantum computation, such as the Ising interaction, Toffoli, and T gates, arise naturally as path integrals in various topological quantum field theories, with their specific magic-generating properties determined by the underlying algebraic data and topological structures of the theories.

The Spurion Massive EFT (SMEFT)

This paper introduces a spurion analysis of SMEFT low-energy amplitudes based on the Higgs VEV to derive the textures of W- and Z-boson masses, mixing, and fermion couplings, demonstrating that these structures are saturated by dimension-eight contributions.

Generalized Complexity Distances and Non-Invertible Symmetries

This paper generalizes quantum gate complexity and geometric distance measures to non-invertible symmetries in quantum field theories, demonstrating that such symmetries define parallel computation schemes involving post-selection and revealing that their simple objects can be computationally highly complex.

Beyond the Dilute Instanton Gas: Resurgence with Exact Saddles in the Double Well

Probing $\tau$ lepton dipole moments at future Lepton Colliders

This study demonstrates that future lepton colliders, specifically the Future Circular Collider and a multi-TeV muon collider, can significantly improve constraints on $\tau$ lepton dipole moments by several orders of magnitude through various production and decay channels, thereby offering a powerful probe for new physics beyond the Standard Model.

Quantum correction to the diffusion term in stochastic inflation from composite-operator matching in Soft de Sitter Effective Theory

This paper develops a composite-operator renormalization and matching formalism within Soft de Sitter Effective Theory to compute the first next-to-leading order (two-loop) quantum correction to the diffusion term in the stochastic inflation Fokker-Planck equation.

Cornering MeV-GeV Axions and Dark Photons with LDMX

This paper investigates the sensitivity of the Light Dark Matter eXperiment (LDMX) to MeV-GeV axions and dark photons, demonstrating that its near-target tracking capabilities could effectively close the long-standing experimental blind spot in the sub-100 MeV mass range where current prompt-decay and beam-dump searches are ineffective.
