In electronic structure calculations, Kohn-Sham equations rank among the most widely adopted mathematical models. However, due to the deficiency of available approximations for exchange-correlation en...
Superconductors – metals in which electricity flows without resistance – hold promise as the defining material of the near future, according to physicist Brad Ramshaw, and are already used in medical ...
Electrons in metals try to behave like obedient motorists, but they end up more like bumper cars. They may be reckless drivers, but a new Cornell-led study confirms this chaos has a limit established ...
There’s a particular set of chemical reactions that governs many of the processes around us—everything from bridges corroding in water to your breakfast breaking down in your gut. One crucial part of ...
The concept of “valence” – the ability of a particular atom to combine with other atoms by exchanging electrons – is one of the cornerstones of modern chemistry and solid-state physics.Valence control...
‘Hot’ electrons don’t mind the gap     Hot  electrons  don’t mind  gap       2017/7/20
If they’re quick about it, “hot” electrons excited in a plasmonic metal can tunnel their way across a nanoscale gap to a neighboring metal. Rice University scientists said the cool part is what happen...
Common sense might dictate that for an object to move from one point to another, it must go through all the points on the path.“Imagine someone driving from Kansas City to Topeka on I-70 — it’s safe t...
Researchers at Princeton University have observed a bizarre behavior in a strange new crystal that could hold the key for future electronic technologies. Unlike most materials in which elec...
While a classical bit found in conventional electronics exists only in binary one or zero states, the more resourceful quantum bit, or ‘qubit,’ is represented by a vector, pointing to a simultaneous c...
UNIVERSITY PARK, Pa. -- Current computing is based on binary logic -- zeroes and ones -- also called Boolean computing, but a new type of computing architecture stores information in the frequencies a...
HOUSTON – (Jan. 30, 2014) – Plasmonic nanoparticles developed at Rice University are becoming known for their ability to turn light into heat, but how to use them to generate electricity is not nearly...
We present a Monte Carlo code dedicated to the simulation of bremsstrahlung arising in collisions of polarized electrons with thin target foils. The program consists of an electron transport algorithm...
A new concept of remote detection of concealed radioactive materials has been recently proposed \cite{Gr.Nusin.2010}-\cite{NusinSprangle}. It is based on the breakdown in air at the focal point of a h...
In a recent paper "Head-on collision of electron acoustic solitary waves in a plasma with nonextensive hot electrons" [Astrophys. Space Sci. 338, 271-278 (2012)] Eslami, Mottaghizadeh and Pakzad deal ...
Starting with a nearest-neighbors tight-binding model, we rigorously investigate the bulk zero-field orbital susceptibility of a non-interacting Bloch electrons gas in graphene-like solids at fixed te...
