Sentences with phrase «electron density wave»

Moreover, they showed that the electrons making up the electron density wave have the characteristic momentum at which the pseudogap appears.

«Unraveling the complex, intertwined electron phases in a superconductor: Scientists may have discovered a link between key components of the «electron density wave» state and the pseudogap phase in a high - temperature superconductor.»

The phenomenon they studied is known as an electron density wave.

The novel experimental approach and the concept of the study itself were conceived after one of the paper's authors, Harvard University theoretical physicist Subir Sachdev, pondered the differing electron density wave behavior along the different bonds of the CuO2 unit cell.

Not exact matches

At a high enough electron density, each cloud reflects high - frequency radio waves like a mirror.

The key lies not in individual reactions between neutrinos and electrons, but in the way the vast numbers of neutrinos affect wave - like fluctuations in the density of electrons in the plasma, known as «plasma waves».

Unlike the other electrons in the material, which move about freely, the density wave is a periodic, fixed electron phase that seems to compete with and hinder the superconducting phase.

Last year, along with researchers led by Brookhaven / Columbia University School of Engineering physicist Simon Billinge, the team established the first firm link between the disappearance of the density wave within the pseudogap phase and the emergence, as stated by Davis, of «universally free - flowing electrons needed for unrestricted superconductivity» [see: https://www.bnl.gov/newsroom/news.php?a=11637].

«This is the first time an experiment has directly linked the disappearance of the density waves and their associated nanoscale crystal distortions with the emergence of universally free - flowing electrons needed for unrestricted superconductivity,» said lead author J.C. Séamus Davis, a senior physicist and Director of DOE's Center for Emergent Superconductivity at Brookhaven Lab and also a professor at both Cornell University and the St. Andrews University in Scotland.

«We are demonstrating that when the electrons are no longer hampered by the «frozen» density wave state, they become universally free to flow unimpeded,» Davis said.

«This is the first direct observation that these two phenomena are linked: The density waves with their associated nanoscale distortions disappear and the electrons in the material change their personality suddenly at a well - defined material composition,» Billinge said.

Electrons traveling through such a narrow path — racing along in what are called charge - density waves — can be easily reversed by virtually any obstacle.

Plasmonic interferometers make use of the interaction between light and surface plasmon polaritons, density waves created when light energy rattles free electrons in a metal.

The relatively high density of plasma in the cloud prevents the formation of electromagnetic waves that would otherwise accelerate electrons to high speeds, turning them into a form of radiation.

The first is the FIELDS experiment which will examine the different fields in the corona, including the Sun's magnetic field, electric fields, waves, plasma density, electron temperature, density fluctuations and radio emissions.

In cuprate superconductors, another state blocks and interacts with superconductivity: the charge - density - wave, in which the electrons assume a static pattern, different from the pattern that the material's crystal structure defines.

This image — a still - frame from an animation (linked here)-- shows how waves of energy from the earthquake and tsunami propagated up to the edge of space and disturbed the density of the electrons in the ionosphere.

what exactly is it that determines the probability of an energy transition such as an electron emitting or absorbing a photon (besides densities and occupancies of states and incident photons, etc.)-- and how does refractive index affect this (it has to because the Planck function is proportional to n ^ 2 — has to be in order to satisfy 2nd law of thermo...)-- and does it make sense to use an k, E diagram when electrons are not actually propagating as plane waves — I mean, what is the wavevector when the waveform is not a plane wave; is k a function of space in atomic orbitals?
