Active Particles in Tunable Compressible Environments

open access: yesSmall Science, Volume 6, Issue 5, May 2026.
Gold‐capped active microparticles powered by electric fields plough their way through a matrix of repulsive spheres, shoveling them aside. At high densities and field strengths, an initial strong direction fluctuation may compress the matrix asymmetrically and lead to an asymmetric reaction favoring sustained turns to the same side (spontaneous ...

Effect of Field Line Torsion on the Polarization of ULF Waves

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract In this paper we suggest a simple modification of the dipole magnetic field which introduces field‐aligned currents and torsion to the field lines. The resulting field lines are not contained in the meridional planes and have resemblance to the geomagnetic field lines in the dawn and dusk flanks of the magnetosphere. We analyze polarization of

Lorentzian homogeneous structures with indecomposable holonomy

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 5, May 2026.
Abstract For a Lorentzian homogeneous space, we study how algebraic conditions on the isotropy group affect the geometry and curvature of the homogeneous space. More specifically, we prove that a Lorentzian locally homogeneous space is locally isometric to a plane wave if it admits an Ambrose–Singer connection with indecomposable, non‐irreducible ...

Adaptive Twisting Metamaterials

open access: yesAdvanced Materials, Volume 38, Issue 21, 13 April 2026.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

On Gauge‐Invariant Entire Function Regulators and UV Finiteness in Non Local Quantum Field Theory

open access: yesAnnalen der Physik, Volume 538, Issue 4, April 2026.
We regulate the theory with an entire function of the covariant operator F(□/M∗2)$F(\square /M^{2}_{*})$. In the perturbative vacuum this becomes a momentum‐space factor F(−p2/M∗2)$F(-p^{2}/M^{2}_{*})$ that exponentially damps high momenta, most transparent after Wick rotation, rendering loop integrals UV finite.
