Albert Einstein's Methodology [PDF]
arXiv, 2012 This paper discusses Einstein's methodology. 1. Einstein characterized his work as a theory of principle and reasoned that beyond kinematics, the 1905 heuristic relativity principle could offer new connections between non-kinematical concepts. 2. Einstein's creativity and inventiveness and process of thinking; invention or discovery. 3.

Molecular Domino Toppling for Directed Self‐Erasing Information Transfer
Advanced Materials, EarlyView.An azobenzene‐based material with unprecedented light‐pumped directional charge‐transfer reminiscent of toppling dominoes is presented. After light‐induced trans→cis forward isomerization, electron hopping occurs in a sequential and propagating manner between the cis isomers along with an electrocatalytic cis→trans backward isomerization.

A Note on Einstein Sasaki Metrics in D \ge 7
, 2004 In this paper, we obtain new non-singular Einstein-Sasaki spaces in dimensions D\ge 7. The local construction involves taking a circle bundle over a (D-1)-dimensional Einstein-Kahler metric that is itself constructed as a complex line bundle over a ...

Advanced Materials, Volume 37, Issue 13, April 2, 2025.Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

On pseudo-Hermitian Einstein spaces [PDF]
arXiv, 2005 We describe and construct here pseudo-Hermitian structures $\theta$ without torsion (i.e. with transversal symmetry) whose Webster-Ricci curvature tensor is a constant multiple of the exterior differential $d\theta$. We call these structures pseudo-Hermitian Einstein and our result states that they all can be derived locally from K{\"a}hler-Einstein ...

Bismut Einstein metrics on compact complex manifolds [PDF]
arXiv, 2022 We observe that, for a Bismut Einstein metric, the (2,0)-part of Bismut Ricci form is an eigenvector of the Chern Laplacian. With the help of this observation, we prove that a Bismut Einstein metric with non-zero Einstein constant is K\"ahler Einstein.

Advanced Materials Interfaces, EarlyView.This paper reviews the relevant work regarding electrostatic effects in X‐ray photoemission from self‐assembled monolayers. It is shown that these effects should be frequently considered at an equal footing as the generally accepted chemical shift ones for correct interpretation of the spectra. In addition, electrostatic effects represent a unique tool

Einstein solvmanifolds with a simple Einstein derivation [PDF]
arXiv, 2007 The structure of a solvable Lie groups admitting an Einstein left-invariant metric is, in a sense, completely determined by the nilradical of its Lie algebra. We give an easy-to-check necessary and sufficient condition for a nilpotent algebra to be an Einstein nilradical whose Einstein derivation has simple eigenvalues.
