This concept is based on a recent demonstration of the optical frequency modulation of the free-electron quantum electron wave function by an ultrafast laser beam, and it is asserted that pulses of such QEWs correlated in their modulation phase, interact resonantly with two-level systems, inducing resonant quantum transitions.

Abstract Contact electrification (CE) is one of the oldest topics in physics, which has been discussed for more than 2600 years. Recently, an overlapped electron‐cloud (OEC) model was proposed by Wang to explain all types of CE phenomena for general materials in which a deep overlapping of electron clouds belonging to two atoms results in a lowered potential barrier for electron transfer from one to the other by applying a compressive force, which is simply referred to as Wang transition for CE. Here, the degree of electron‐cloud overlap between two atoms is controlled by using tapping mode at...

Electron-phonon coupling, being one of the most important parameters governing the material evolution after ultrafast energy deposition, yet remains the most unexplored one. In this work, we applied the dynamical coupling approach to calculate the nonadiabatic electron-ion energy exchange in nonequilibrium solids with the electronic temperature high above the atomic one. It was implemented into the tight-binding molecular dynamics code, and used to study electron-phonon coupling in various elemental metals. The developed approach is a universal scheme applicable to electronic temperatures up t...

For the needs of food producers and consumers, electronic tongue and electronic nose play many roles for food quality and safety in food production, food supervision and daily life. The principles and progresses of electronic tongue and electronic nose were elaborated. The core hardware namely electronic tongue sensors and electronic nose sensors, and the core software namely intelligent sensory algorithms were summarized. It was found that the proportion of electronic tongue and electronic nose employed in food quality control and monitoring in production was the highest. Electronic tongue an...

The study of electronic structure of materials is at a momentous stage, with new computational methods and advances in basic theory.

New in the second edition are recent advances in density functional theory, an introduction to Berry phases and topological insulators ex...

Abstract Within the broad and deep field of topological materials, there are an ever-increasing number of materials that harbor topological phases. While condensed matter physics continues to probe the exotic physical properties resulting from the existence of topological phases in new materials, there exists a suite of “well-known” topological materials in which the physical properties are well-characterized, such as Bi 2 Se 3 and Bi 2 Te 3 . In this context, it is then appropriate to ask if the unique properties of well-explored topological materials may have a role to play in applications t...

Abstract Organic electronics is a platform for very low cost and high performance optoelectronic and electronic devices that cover large areas, are lightweight, and can be both flexible and conformable to irregularly shaped surfaces such as foldable smart phones. Organics are at the core of the global organic light emitting device (OLED) display industry, and also having use in efficient lighting sources, solar cells, and thin film transistors useful in medical and a range of other sensing, memory and logic applications. This book introduces the theoretical foundations and practical realizatio...

A circuit of electron flow in the mammalian ETC that maintains mitochondrial functions under oxygen limitation is delineated, finding that complex I and dihydroorotate dehydrogenase can still deposit electrons into the ETC when oxygen reduction is impeded.

Note: Nano-photonics or nano-optics includes metal components that can transmit and focus light, often refers to ultraviolet, visible and infrared rays, whose wavelength ranges from 300 to 1200 nm. Nano lasers are one of the components of Nano Photonics.Nanophotonics or nanooptics is the study of the behavior of light based on the interactions of optical material science and engineering, at wavelength and wavelength scales, where natural or chemical projects of nanostructured natural materials or nanotechnology at scale Nanophotonics and synthetics using optics including silicon-based semicond...

It is shown that ultrafast electron diffraction can be used to simultaneously record both electronic and nuclear dynamics in isolated pyridine molecules, naturally disentangling the two components.

There are currently several existing and proposed experiments designed to\nprobe sub-GeV dark matter (DM) using electron ionization in various materials.\nThe projected signal rates for these experiments assume that this ionization\nyield arises only from DM scattering directly off electron targets, ignoring\nsecondary ionization contributions from DM scattering off nuclear targets. We\ninvestigate the validity of this assumption and show that if sub-GeV DM couples\nwith comparable strength to both protons and electrons, as would be the case\nfor a dark photon mediator, the ionization signal f...

Abstract In this study, by simulating the wave‐particle interactions, we show that subrelativistic/relativistic electron microbursts form the high‐energy tail of pulsating aurora (PsA). Whistler‐mode chorus waves that propagate along the magnetic field lines at high latitudes cause precipitation bursts of electrons with a wide energy range from a few kiloelectron volts (PsA) to several megaelectron volts (relativistic microbursts). The rising tone elements of chorus waves cause individual microbursts of subrelativistic/relativistic electrons and the internal modulation of PsA with a frequency ...

Over the last decade, extensive efforts have been made on utilizing advanced materials and structures to improve the properties and functionalities of flexible electronics. While the conventional ways are approaching their natural limits, a revolutionary strategy, namely metamaterials, is emerging toward engineering structural materials to break the existing fetters. Metamaterials exhibit supernatural physical behaviors, in aspects of mechanical, optical, thermal, acoustic, and electronic properties that are inaccessible in natural materials, such as tunable stiffness or Poisson's ratio, manip...
