Discriminating quantum gravity models by gravitational decoherence

open access: yesNuclear Physics B, 2023
Several phenomenological approaches to quantum gravity predict the existence of a minimal measurable length and/or a maximum measurable momentum near the Planck scale.

Multifunctional Bio‐Based Packaging for Perishable Foods: Structural Design, Scalable Fabrication, and Versatile Applications

open access: yesAdvanced Materials, Volume 38, Issue 33, 12 June 2026.
An overview of design principles and scalable fabrication strategies for multifunctional bio‐based packaging. Radiative cooling films, modified‐atmosphere films/membranes, active antimicrobial/antioxidant platforms, intelligent optical/electrochemical labels, and superhydrophobic surfaces are co‐engineered from material chemistry to mesoscale structure

A histories perspective on characterizing quantum non-locality [PDF]

open access: yes, 2014
We introduce a framework for studying non-locality and contextuality inspiredby the path integral formulation of quantum theory. We prove that the existenceof a strongly positive joint quantum measure— the quantum analogue of a jointprobability measure —

Magnetically Actuated Drops‐on‐Stilts Microrobots for Transport and Delivery of Hydrophobic Cargo

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
Iron oxide nanoparticles and oil droplets in external magnetic fields form “drops‐on‐stilts” microrobots that transport hydrophobic cargo. Tunable nanoparticle–droplet interactions generate stilt‐like structures. Field rotation enables walking, obstacle navigation, and collective motion.

Nonperturbative solutions for canonical quantum gravity: An overview [PDF]

open access: yesPhysics Reports, 1997
In this paper we will make a survey of solutions to the Wheeler-Dewitt equation which have been found up to now in Ashtekar's formulation for canonical quantum gravity. Roughly speaking they are classified into two categories, namely, Wilson-loop solutions and topological solutions.

Wave Mechanics of Ciliary Proteins: Quantum‐Enabled Sensing and Energy Transfer in the “Cellular Antenna”

open access: yesAggregate, Volume 7, Issue 6, June 2026.
This review surveys eukaryotic cilia as putative quantum‐enabled sensory and regulatory centers. It highlights their multifaceted roles in the cell, focuses on the nontrivial roles of quantum mechanics in their membrane and cytoskeletal proteins, and introduces the essential building blocks enabling quantum properties to survive in the warm, wet, and ...

On the Meaning of Localization in Non‐Local Quantum Field Theory

open access: yesAnnalen der Physik, Volume 538, Issue 6, June 2026.
In non‐local quantum field theory nature does not necessarily allow objects or events to be localized to exact mathematical points. Instead any physical measurement has a built‐in finite resolution set by the non‐locality scale. Spacetime remains continuous and Lorentz‐covariant, but below this scale pointlike localization becomes an idealization ...

Quantum Gravity Meets &HPS [PDF]

open access: yes, 2010
I examine the early history of quantum gravity and comment on its suitability as an episode that demands an integrated approach to history and philosophy of ...

Symplectic reduction and the problem of time in nonrelativistic mechanics [PDF]

open access: yes, 2010
Symplectic reduction is a formal process through which degeneracy within the mathematical representations of physical systems displaying gauge symmetry can be controlled via the construction of a reduced phase space. Typically such reduced spaces provide
