Using a computer-assisted wave generator, scientists produced a train of solitons in a 110-meter-long water tank in Berlin, recreating in water the mathematical results of a famous 1960s computer experiment. This wave generation was part of a project in...
In (a) an originally obtained picture of a one-dimensional atomic chain is shown. The thick horizontal lines illustrate the barrier between different chains. In each chain, an atom appearing on the upper side of the thin dashed horizontal line...

Scientists have, for the first time, identified a method of visualising the quantum behaviour of electrons on a surface. The findings present a promising...
The distribution of the laser intensity (orange), the foil electron and foil ion densities (gray), and the positron density (red) in the x--y plane. The laser pulse propagates along the x-axis, while the foil surface is perpendicular to the...
An illustration shows how laser light excites electrons (white spheres) in a solid material, creating vibrations in its lattice of atomic nuclei (black and blue spheres). SLAC’s LCLS X-ray laser reveals the ultrafast “dance” between electrons and vibrations that...
"Learning from this model, we can understand what's really going on in these superconductors, and what one should do to make higher-temperature superconductors, approaching hopefully room temperature," says Martin Zwierlein, professor of physics and principal investigator in MIT's Research...
The spinning rainbow surface of a soap bubble is more than mesmerizing -- it's a lesson in fluid mechanics. Better understanding of these hypnotic flows could bring improvements in many areas, from longer lasting beer foam to life-saving lung...
A schematic of cosmic history. Astronomers have called attention to a neglected riddle of the expansion: although the outward flaring seen in the graphic (representing cosmic acceleration) might have started at any time, curiously it has happened in our...

Scientists at the High Energy Physics Group (HEP) of the University of the Witwatersrand in Johannesburg predict...
An illustration shows what happens in a typical experiment with SLAC’s LCLS X-ray laser, top, versus what happened in this study with an especially intense X-ray pulse. Normally the X-ray pulses -- which are shown coming in from the...
Associate Professor Dr Joan Vaccaro, of Griffith's Centre for Quantum Dynamics, has solved an anomaly of conventional physics and shown that a mysterious effect called 'T violation' could be the origin of time evolution and conservation laws.
"I begin by...
