TRACERS Small‐Scale Field‐Aligned Currents and Intense GPS Amplitude and Phase Scintillations in the Nightside Auroral Region

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We present conjugate observations of ionospheric small‐scale magnetic perturbations (dB) $(dB)$ and GPS scintillations from the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) and the Canadian High Arctic Ionospheric Network (CHAIN) during a storm‐time substorm on 9 August 2025 in the nightside auroral region ...

Overcoming Computational Bottlenecks in Quantum Hydrodynamics: A Volume‐Based Integral Formalism for Spherical Nanoparticles

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Numerical modeling of mesoscopic material response models that capture the quantum dynamics of electrons does not have to come with discouraging computational bottlenecks. The main message is that through a shift in perspective in modeling toward integral equation methods and exploiting symmetry‐based arguments, it is possible to capture complicated ...

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

Advanced Materials Interfaces, Volume 13, Issue 13, 7 July 2026.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.

Electromagnetic Response of Two Interacting Topological Insulator Spheres in External Fields

Annalen der Physik, Volume 538, Issue 7, July 2026.
ABSTRACT We study the static electromagnetic response of two spherical topological insulators embedded in a dielectric medium and subjected to a uniform external electric field. The gapped surface states are described by a piecewise constant axion field, which induces a topological magnetoelectric coupling localized at the spherical interfaces.

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review

Advanced Physics Research, Volume 5, Issue 7, July 2026.
Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

A proposed measurement of optical orbital and spin angular momentum and its implications for photon angular momentum

Physics Letters B, 2018
The expression for the total angular momentum carried by a laser optical vortex beam, splits, in the paraxial approximation, into two terms which seem to represent orbital and spin angular momentum respectively.

Chemical Shift Separated and Compensated Ultra‐Short Echo‐Time Imaging

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 121-133, July 2026.
ABSTRACT Purpose To develop a modified binomial excitation scheme for ultra‐short echo‐time (UTE) imaging that allows for the separation of water and fat signals and the correction of chemical shift artifacts. Methods Theoretical derivation and numerical Bloch simulations were performed for a modified water‐excitation binomial pulse scheme to calculate

Classical electrodynamics in a space with spin noncommutativity of coordinates

Physics Letters B, 2016
We propose a relativistic Lorentz-invariant spin-noncommutative algebra. Using the Weyl ordering of noncommutative position operators, we find a mapping from a space of commutative functions into space of noncommutative functions.

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

Natural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at
