All-Optical Lithography for Azopolymer Microreliefs

Published:Dec 31, 2025 18:44
1 min read
ArXiv

Analysis

This paper introduces a novel all-optical lithography platform for creating microstructured surfaces using azopolymers. The key innovation is the use of engineered darkness within computer-generated holograms to control mass transport and directly produce positive, protruding microreliefs. This approach eliminates the need for masks or molds, offering a maskless, fully digital, and scalable method for microfabrication. The ability to control both spatial and temporal aspects of the holographic patterns allows for complex microarchitectures, reconfigurable surfaces, and reprogrammable templates. This work has significant implications for photonics, biointerfaces, and functional coatings.

Constructing Covariant Actions for Quantum Gravity with a Unique Vacuum

Published:Dec 31, 2025 16:45
1 min read
ArXiv

Analysis

This paper addresses the ambiguity in the vacuum sector of effective quantum gravity models, which hinders phenomenological investigations. It proposes a constructive framework to formulate 4D covariant actions based on the system's degrees of freedom (dust and gravity) and two guiding principles. This framework leads to a unique and static vacuum solution, resolving the 'curvature polymerisation ambiguity' in loop quantum cosmology and unifying the description of black holes and cosmology.
Reference

“The constructive framework produces a fully 4D-covariant action that belongs to the class of generalised extended mimetic gravity models.”

Vortex Pair Interaction with Polymer Layer

Published:Dec 31, 2025 16:10
1 min read
ArXiv

Analysis

This paper investigates the interaction of vortex pairs with a layer of polymeric fluid, a problem distinct from traditional vortex-boundary interactions in Newtonian fluids. It explores how polymer concentration, relaxation time, layer thickness, and polymer extension affect energy and enstrophy. The key finding is that the polymer layer can not only dissipate vortical motion but also generate new coherent structures, leading to transient energy increases and, in some cases, complete dissipation of the primary vortex. This challenges the conventional understanding of polymer-induced drag reduction and offers new insights into vortex-polymer interactions.
Reference

“The formation of secondary and tertiary vortices coincides with transient increases in kinetic energy, a behavior absent in the Newtonian case.”

Hierarchical Dynamics in Glassy Microgel Suspensions

Published:Dec 31, 2025 14:37
1 min read
ArXiv

Analysis

This paper investigates the dynamics of ultra-low crosslinked microgels in dense suspensions, focusing on their behavior in supercooled and glassy regimes. The study's significance lies in its characterization of the relationship between structure and dynamics as a function of volume fraction and length scale, revealing a 'time-length scale superposition principle' that unifies the relaxation behavior across different conditions and even different microgel systems. This suggests a general dynamical behavior for polymeric particles, offering insights into the physics of glassy materials.
Reference

“The paper identifies an anomalous glassy regime where relaxation times are orders of magnitude faster than predicted, and shows that dynamics are partly accelerated by laser light absorption. The 'time-length scale superposition principle' is a key finding.”

Discrete Feynman-Kac Approximation for Parabolic Anderson Model

Published:Dec 28, 2025 09:00
1 min read
ArXiv

Analysis

This paper introduces a novel, positive approximation method for the parabolic Anderson model, leveraging the Feynman-Kac representation and random walks. The key contribution is an error analysis for the approximation, demonstrating a convergence rate that is nearly optimal, matching the Hölder continuity of the solution. This work is significant because it provides a quantitative framework for understanding the convergence of directed polymers to the parabolic Anderson model, a crucial connection in statistical physics.
