International Journal of Modern Physics D, 2014 This paper presents an "in-a-nutshell" yet self-contained introductory review on loop quantum gravity (LQG) — a background-independent, nonperturbative approach to a consistent quantum theory of gravity. Instead of rigorous and systematic derivations, it aims to provide a general picture of LQG, placing emphasis on the fundamental ideas and their ...

3D Printed Magnetic Origami Scaffolds for Guided Tissue Assembly
Advanced Materials Interfaces, EarlyView.3D‐printed magnetic origami scaffolds enhance 3D coculture by directing cell proliferation pre‐folding, restricting expansion for controlled growth within the channel, and spatially and temporally promoting 3D multicellular dissemination post‐folding.

The information metric on the moduli space of instantons with global symmetries
Physics Letters B, 2016 In this note we revisit Hitchin's prescription [1] of the Fisher metric as a natural measure on the moduli space of instantons that encodes the space–time symmetries of a classical field theory. Motivated by the idea of the moduli space of supersymmetric

Fakeons, microcausality and the classical limit of quantum gravity [PDF]
Classical and quantum gravity, 2018 We elaborate on the idea of fake particle and study its physical consequences. When a theory contains fakeons, the true classical limit is determined by the quantization and a subsequent process of ‘classicization’.

QUANTUM GRAVITY AND TURBULENCE [PDF]
International Journal of Modern Physics D, 2010 We apply recent advances in quantum gravity to the problem of turbulence. Adopting the AdS/CFT approach we propose a string theory of turbulence that explains the Kolmogorov scaling in 3 + 1 dimensions and the Kraichnan and Kolmogorov scalings in 2 + 1 dimensions.

Advanced Optical Materials, EarlyView.This study investigates CsPbBr3 nanowire (NW) array synthesis and stability using nanoporous anodized aluminum oxide (AAO) templates. Simulations identify optimal pore geometries for light–matter interactions (LMI). The ligand‐free modified inverse temperature crystallization (ITC) method is utilized for NW array growth, providing insights into a broad

The ultraviolet behavior of quantum gravity [PDF]
, 2018 A bstractA theory of quantum gravity has been recently proposed by means of a novel quantization prescription, which is able to turn the poles of the free propagators that are due to the higher derivatives into fakeons.
