Polar gravitational perturbations and quasinormal modes of a loop quantum gravity black hole
, 2020 In this work, we have calculated the polar gravitational quasinormal modes for a quantum corrected black hole model, that arises in the context of Loop Quantum Gravity, known as Self-Dual Black Hole.

Adsorption and Separation by Flexible MOFs
Advanced Materials, EarlyView.Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,

Loop quantum cosmology and singularities
Scientific Reports, 2017 Loop quantum gravity is believed to eliminate singularities such as the big bang and big crunch singularity. This belief is based on studies of so-called loop quantum cosmology which concerns symmetry-reduced models of quantum gravity. In this paper, the

Towards Cosmological Dynamics from Loop Quantum Gravity [PDF]
, 2018 We present a systematic study of the cosmological dynamics resulting from an effective Hamiltonian, recently derived in loop quantum gravity (LQG) using Thiemann's regularization and earlier obtained in loop quantum cosmology (LQC) by keeping the ...

Beyond Conventional Cooling: Advanced Micro/Nanostructures for Managing Extreme Heat Flux
Advanced Materials, EarlyView.This review examines the design, application, and manufacturing of biomimetic or engineered micro/nanostructures for managing high heat‐flux in multi‐level electronics by enhancing conductive, convective, phase‐changing, and radiative heat transfer mechanisms, highlighting their potential for efficient, targeted thermal management, and future prospects.

Enrichment of Hypermethylated DNA on Chip for Cervical Cancer Detection
Advanced Materials Interfaces, EarlyView.A microfluidic chip coated with surface‐immobilized methyl binding domain 2 (MBD‐2) protein receptors, is able to bind hypermethylated DNA (hmDNA) from a cancer cell line selectively. Quantification by quantitative polymerase chain reaction (qPCR) shows a 30‐fold enrichment in cervical cancer target DNA.

No fermion doubling in quantum geometry
Physics Letters B, 2015 In loop quantum gravity the discrete nature of quantum geometry acts as a natural regulator for matter theories. Studies of quantum field theory in quantum space–times in spherical symmetry in the canonical approach have shown that the main effect of the

Does a Theory of Everything Exist?
Философия и космология, 2021 Since Einstein’s failure to define a Grand Unified Theory, physicists have pursued a comprehensive theory explaining nature, a Theory of Everything. But because General Relativity, Quantum Field Theory, and Cosmology have little in common, defining one ...
