PROVIDENCE, R.I. [Brown University] — New research by physicists from Brown University puts the profound strangeness of quantum mechanics in a nutshell — or, more accurately, in a helium bubble.

Physicists have now demonstrated experimentally the ability to coherently manipulate the wave function of a free electron down to the attosecond timescale (10-18 of a second). The team also developed ...

Quantum nano-mechanics. Quantum jumps in atomic physics. Continuous transitions between quantum states in quantum‒classical mechanics for molecular and chemical physics involve both chaotic (dozy ...

July 12 (UPI) --Scientists at the Swiss Federal Institute of Technology in Lausanne have developed a new method for exciting and controlling the energy inside an atomic nucleus. The new method relies ...

INTRODUCTION: Density functional theory (DFT) is a widely used method for calculating the electronic properties of materials. The method is based on the idea of approximating the many-electron wave ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...

Fractals are a source of endless fascination to me. Life itself relies on many of the concepts of fractals: trees are fractal, as are feathers, coast lines, and many other things in nature. Indeed, it ...

In a proof-of-concept study, researchers have created self-assembled, protein-based circuits that can perform simple logic functions. The work demonstrates that it is possible to create stable digital ...

Monte Carlo track structure codes provide valuable information for understanding radiation effects down to the DNA level, where experimental measurements are most difficult or unavailable. It is well ...

The time it takes for a single particle of light to pass through a hydrogen molecule is now the shortest duration ever measured. This interval was about 247 zeptoseconds, or trillionths of a billionth ...
