Blazar flares from plasma blobs crossing the broad-line region

Sebastien Le Bihan, Anton Dmytriiev, Andreas Zech · 2026

The blazar 3C 279 is well known for its rapid and large-amplitude variability. On 20 December 2013, the source exhibited an orphan {\gamma}-ray flare characterized by a flux-doubling timescale of a fe…

Kolmogorov-Sinai entropies identify optimal observables for prediction and dynamics reconstruction in chaotic systems

Maximilian Topel · 2026

Choosing the optimal observable to model dynamical systems for which we do not know the driving equations is nearly always an ad hoc art. Takens' Delay Embedding Theorem guarantees a diffeomorphism be…

Revisiting the mixing length scaling in pressure-gradient turbulent boundary layers via a symmetry approach

Weitao Bi · 2026

A century after Prandtl's mixing length hypothesis, full-profile scaling of the mixing length in pressure-gradient turbulent boundary layers (PG TBLs) remains debated, especially for adverse pressure …

Collisional energy loss distribution of a fast parton in a hot or dense QCD medium

G. Jackson, S. Peigne · 2026

We compute the probability distribution for collisional energy loss of an ultrarelativistic parton crossing a quark-gluon plasma. This collisional quenching weight has not been determined previously, …

A Lie-algebraic Criterion for the Universality of Exponentiated Quantum Gates

Yinuo Xue, Qian Chen, Jing-Song Huang · 2026

We present a criterion that serves as the basis for a polynomial-time algorithm to decide whether a finite set of qudit gates exponentiated by some Hamiltonians is universal. Our approach formulates u…

Multi-tracers, multi-surveys: data-driven EFT prior calibration from the PFS--DESI overlap

Nhat-Minh Nguyen · 2026

Marginalizing over roughly 12 effective-field-theory (EFT) nuisance parameters per tracer per redshift bin is the dominant systematic cost in full-shape galaxy power spectrum analyses. Simulation-base…
