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.

Quantum state correction of relic gravitons from quantum gravity [PDF]
Phys.Rev.D55:4791-4794,1997, 1996 The semiclassical approach to quantum gravity would yield the Schroedinger formalism for the wave function of metric perturbations or gravitons plus quantum gravity correcting terms in pure gravity; thus, in the inflationary scenario, we should expect correcting effects to the relic graviton (Zel'dovich) spectrum of the order (H/mPl)^2.

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’.

Photochromic Molecules Enable Optical Control of Optomechanical Coupling in a Cavity
Advanced Optical Materials, EarlyView.An optomechanical system with optically‐tunable coupling is introduced, featuring a multilayered membrane with a photochromic molecule and NIR‐absorbing dye. Laser cooling of a membrane vibrational mode is evidenced, with a 60% improvement in efficiency achieved upon photoisomerization, as well as reversible control of photothermal forces.

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

Zooming in on fermions and quantum gravity [PDF]
Physical Review D, 2018 We zoom in on the microscopic dynamics for fermions and quantum gravity within the asymptotic-safety paradigm. A key finding of our study is the unavoidable presence of a nonminimal derivative coupling between the curvature and fermion fields in the ...
