Non‐Markovian Exceptional Points in Waveguide Quantum Electrodynamics
Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.Non‐Markovian waveguide‐QED systems exhibit dynamical transitions governed by exceptional points arising from retardation and interference. Giant atoms and spatially separated emitters display oscillatory relaxation and real zeros in the excited‐state amplitude at critical delay times.

A New Orthogonal Geomagnetic Coordinate System: The Generalized Eccentric Dipole
Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.Abstract The study of near‐Earth plasma environment relies heavily on accurate geomagnetic coordinate systems, mainly because the plasma motion is controlled by the E×B $\boldsymbol{E}\times \boldsymbol{B}$ drift and thus is constrained by the structure of the magnetic field.

The L$L$‐polynomials of van der Geer–van der Vlugt curves in characteristic 2
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract The van der Geer–van der Vlugt curves form a class of Artin–Schreier coverings of the projective line over finite fields. We provide an explicit formula for their L$L$‐polynomials in characteristic 2, expressed in terms of characters of maximal abelian subgroups of the associated Heisenberg groups.

Vanishing of Quartic and Sextic Twists of $L$-functions [PDF]
, 2023 Let $E$ be an elliptic curve over $\mathbf{Q}$. We conjecture asymptotic estimates for the number of vanishings of $L(E,1,\chi)$ as $\chi$ varies over all primitive Dirichlet characters of orders 4 and 6, subject to a mild hypothesis on $E$.

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.Distributed bioenergy networks face an unresolved equity challenge: AI dispatch optimisers under‐serve peripheral communities while maximising aggregate throughput. Ethical guardrail bandit pruning enforces fairness and energy sustainability via a two‐timescale primal‐dual guardrail, achieving a 76.6% Gini reduction and 28.5% FLOPs‐proxy reduction ...

Classical Simulation of Quantum Circuits by Half Gauss Sums
, 2022 We give an efficient algorithm to evaluate a certain class of exponential sums, namely the periodic, quadratic, multivariate half Gauss sums. We show that these exponential sums become

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.A research gap exists concerning how different chaotic mappings influence the applicability of metaheuristic algorithms, along with inherent limitations of the traditional artificial hummingbird algorithm (AHA). Specifically, blind spots in population coverage and vulnerability to local optima stemming from random initialization.

A Note on the Classical Gauss Sums
, 2018 The main purpose of this paper is to study the computational problem of one kind rational polynomials of the classical Gauss sums, and using the purely algebraic methods and the properties of the character sums mod p (a prime with p ≡

Explicit multiplicative relations between Gauss sums [PDF]
, 2002 H.Hasse conjectured that all multiplicative relations between Gauss sums essentially follow from the Davenport-Hasse product formula and the norm relation for Gauss sums.

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.To overcome the difficulties of empirical analogy, physical testing, and conventional finite element (FE) simulation in extracting joint stiffness for beam models of shield tunnel linings, we proposed an isogeometric (IG) Reissner–Mindlin (RM) shell model with a narrow layer.
