Gravitational Lensing Effects from Models of Loop Quantum Gravity with Rigorous Quantum Parameters
UniverseMany previous works have studied gravitational lensing effects from Loop Quantum Gravity. So far, gravitational lensing effects from Loop Quantum Gravity have only been studied by choosing large quantum parameters much larger than the Planck scale ...

Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023 A regular array of oriented molecular motors is presented by incorporating overcrowded alkene molecules as linker in metal–organic framework thin films. By switching between the stable and metastable states, the adsorption and diffusion properties of the guest molecules are controlled. Abstract Molecular motors are fascinating nanomachines.

Early universe in quantum gravity
Journal of High Energy PhysicsWe present a new picture of the early universe in finite nonlocal quantum gravity, which is Weyl invariant at the classical and quantum levels. The high-energy regime of the theory consists of two phases, a Weyl invariant trans-Planckian phase and a post-

Experimental Search for Quantum Gravity [PDF]
"Classical and Quantum Gravity: Theory, Analysis and
Applications," Chapter 5, Edited by V. R. Frignanni, Nova Publishers (2011), 2010 We offer a brief survey of existent and planned experimental tests for quantum gravity. First, we outline the questions we wish to address, and then introduce some of the phenomenological models that are currently used in quantum gravity, both with and without a lowered Planck scale. After that, we summarize experimental areas where these models can be

Spring and Power in Hovering Ornithopters
Advanced Intelligent Systems, EarlyView.Only small ornithopters can hover, longest at the hummingbird size. This article reviews the drive and power of these hovering machines, focusing on elastic energy and thrust boosters. Unlike two‐winged designs, X‐winged and multiple‐V‐winged ornithopters benefit from lower disk loading and slower, smaller wingbeats, and the clap‐and‐fling effect ...

The cosmological impact of Brane-Chern-Simons massive gravity
Journal of High Energy PhysicsIn this paper, we present a novel extension of massive gravity theory; the Brane-Chern-Simons massive gravity theory. We explore the cosmological implications of this theory by deriving the background equations and demonstrating the existence of self ...
