Stochastic Dynamics From Maximum Entropy in Action Space

open access: yesFortschritte der Physik, Volume 74, Issue 5, May 2026.
ABSTRACT We develop an information‐theoretic formulation of stochastic dynamics in which the fundamental stochastic variable is the total action connecting spacetime points, rather than individual paths. By maximizing Shannon entropy over a joint distribution of actions and endpoints, subject to normalization and a constraint on the mean action, we ...

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 1646-1660, May 2026.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene

open access: yesSmall, Volume 22, Issue 26, 8 May 2026.
Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

Filling a Gap in Materials Mechanics: Nanoindentation at High Constant Strain Rates up to 105 s−1

open access: yesSmall, Volume 22, Issue 28, 18 May 2026.
A piezoelectric nanoindentation platform enables constant strain‐rate testing up to 105 s−1, extending experimental capabilities to extreme deformation regimes. Distinct hardness upturns are revealed across crystalline and amorphous materials, verified as intrinsic responses through quasi‐static reloading.

Beyond DPA: An Atomistic Framework for a Quantitative Description of Radiation Damage in YBa2Cu3O7

open access: yesSmall Science, Volume 6, Issue 5, May 2026.
To quantify primary radiation damage and describe defect morphology in the high‐temperature superconductor YBa2Cu3O7, an atomistic multiscale framework is proposed. Coupling Molecular Dynamics and Binary Collision Approximation simulations and integrating the atomistic description with Primary Knock‐on Atom spectra from Monte Carlo and transport ...
