Physicists Explore Photon-Photon Elastic Collisions

When one snooker ball hits another, both spring away from each other in an elastic manner. In the case of two photons a similar process – the elastic collision – has never been observed. Physicists from the Institute of Nuclear Physics of the Polish Academy of Sciences have shown, however, that such a process does not only occur, but even could soon be registered in heavy ion collisions at the LHC accelerator.

Unique Rapid-Fire Electron Source Could Help Scientists Study Ultrafast Chemical Processes at Atomic Scale

A unique rapid-fire electron source—originally built as a prototype for driving next-generation X-ray lasers—will help scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) study ultrafast chemical processes and changes in materials at the atomic scale. This could provide new insight in how to make materials with custom, controllable properties and improve the efficiency and output of chemical reactions.

Researchers Use Extremely Precise Technique to Measure Spin Momentum of Light

Ever since Kepler’s observation in the 17th century that sunlight is one of the reasons that the tails of comets to always face away from the sun, it has been understood that light exerts pressure in the direction it propagates. Radiation pressure is produced by the momentum carried by light, and it plays a crucial role in a variety of systems, from atomic to astronomical scales.

Study Results Provide Better Tool for Search of Schrödinger Cat-Like States

In a classical world, objects have pre-existing properties, physical influences are local and cannot travel faster than the speed of light, and it is in principle possible to measure the properties of macroscopic systems without altering them. This is referred to as local realism and macroscopic realism, and quantum mechanics is in strong contradiction with both of them.
