Heavy Quark Transport is Non-Gaussian Beyond Leading Log

This paper demonstrates that heavy quark transport in weakly coupled non-Abelian plasmas is intrinsically non-Gaussian with asymmetric exponential tails beyond the leading logarithm, a robust feature shared with strongly coupled holographic plasmas that is essential for accurate equilibration dynamics.

Subregion Complementarity in AdS/CFT

This paper challenges the validity of standard subregion duality and entanglement wedge reconstruction in AdS/CFT by highlighting discrepancies at leading order and attributing their failure to non-perturbative effects, while proposing a new framework of "subregion complementarity" where distinct CFT operators describe the same bulk subregion, a concept applicable to eternal black holes but not single-sided ones.

Ti and Spi, Carrollian extended boundaries at timelike and spatial infinity

This paper defines invariant, Carrollian-geometric extended boundaries at timelike and spatial infinity (Ti and Spi) for asymptotically flat spacetimes, demonstrating their utility in characterizing asymptotic symmetries, realizing massive field scattering data, and naturally recovering the BMS and Poincaré groups along with Strominger's matching conditions.

Vershik-Kerov in higher times

This paper generalizes the Vershik-Kerov limit shape problem to circular and linear quiver theories, as well as a double-elliptic setting related to six-dimensional gauge theory, proving that the resulting limit shape is governed by a genus two algebraic curve which suggests unexpected dualities between enumerative and equivariant parameters.

Deriving motivic coactions and single-valued maps at genus zero from zeta generators

This paper proves the conjectural reformulation of the motivic coaction and single-valued map for multiple polylogarithms on the Riemann sphere using zeta generators.

Systematic approach to $\ell$-loop planar integrands from the classical equation of motion

This paper introduces a recursive method derived from the classical equation of motion to systematically construct $\ell$-loop planar integrands in colored quantum field theories, a technique that is generalizable to both Lagrangian and non-Lagrangian theories.

The bi-adjoint scalar $\ell$-loop planar integrand recursion and graded inverse variables

This paper introduces a new formalism utilizing "graded inverse variables" to provide a more elegant and clear recursive expression for the $\ell$-loop planar integrands of the bi-adjoint scalar theory, enabling the systematic derivation of graph and symmetry factors from monomials.

Derivative coupling in horizon brightened acceleration radiation: a quantum optics approach

This paper investigates Horizon Brightened Acceleration Radiation (HBAR) using derivative coupling between atoms and field momentum to resolve infrared divergences, revealing that point-like detectors exhibit frequency-independent transition probabilities due to local gravitational effects and that finite-size detectors may induce non-equilibrium thermodynamic states.

Gauge-covariant stochastic neural fields: Stability and finite-width effects

This paper develops a gauge-covariant stochastic effective field theory using the Martin-Siggia-Rose-Janssen-de Dominicis formalism to analyze stability and finite-width effects in deep neural systems, demonstrating that finite-width corrections perturb dressed kernels without altering the mean-field instability threshold while reproducing predicted low-frequency spectral deformations.
