Consolidate Overview of Ribonucleic Acid Molecular Dynamics: From Molecular Movements to Material Innovations

Advanced Engineering Materials, EarlyView.
Molecular dynamics simulations are advancing the study of ribonucleic acid (RNA) and RNA‐conjugated molecules. These developments include improvements in force fields, long‐timescale dynamics, and coarse‐grained models, addressing limitations and refining methods.

Universal quantum modifications to general relativistic time dilation in delocalised clocks [PDF]

Quantum, 2020
The theory of relativity associates a proper time with each moving object via its world line. In quantum theory however, such well-defined trajectories are forbidden. After introducing a general characterisation of quantum clocks, we demonstrate that, in

Global one-dimensionality conjecture within quantum general relativity [PDF]

, 2008
A simple quantum gravity model, based on a new conjecture within the canonically quantized 3 + 1 general relativity, is presented. The conjecture states that matter fields are functionals of an embedding volume form only and reduces the quantum ...

Rotation and Spin in Physics

, 2010
We delineate the role of rotation and spin in physics, discussing in order Newtonian classical physics, special relativity, quantum mechanics, quantum electrodynamics and general relativity. In the latter case, we discuss the generalization of the Kepler

Quantum Correlations and Quantum Non-Locality: A Review and a Few New Ideas [PDF]

, 2019
In this paper we make an extensive description of quantum non-locality, one of the most intriguing and fascinating facets of quantum mechanics. After a general presentation of several studies on this subject, we consider if quantum non-locality, and the ...

First‐Principles Modeling of Solid Solution Softening and Hardening Effects in Al–Mg–Zr–Si Aluminum Alloys

Advanced Engineering Materials, EarlyView.
The role of various alloying elements in face‐centered cubic aluminum on the barrier of a Shockley partial dislocation during its motion is presented. The study aims to understand how alloying atoms such as Mg, Si, and Zr affect the energy landscape for dislocation motion, thus influencing the solid solution hardening and softening in aluminum, which ...

Nonlocal teleparallel cosmology

European Physical Journal C: Particles and Fields, 2017
Even though it is not possible to differentiate general relativity from teleparallel gravity using classical experiments, it could be possible to discriminate between them by quantum gravitational effects. These effects have motivated the introduction of

ON THE RUNNING OF THE COSMOLOGICAL CONSTANT IN QUANTUM GENERAL RELATIVITY [PDF]

, 2009
We present arguments that show what the running of the cosmological constant means when quantum general relativity is formulated following the prescription developed by Feynman.

CLASSICAL AND QUANTUM GENERAL RELATIVITY: A NEW PARADIGM [PDF]

International Journal of Modern Physics D, 2005
We argue that recent developments in discretizations of classical and quantum gravity imply a new paradigm for doing research in these areas. The paradigm consists in discretizing the theory in such a way that the resulting discrete theory has no constraints. This solves many of the hard conceptual problems of quantum gravity.
