Researchers seeking the fourth property of electrons

Do electrons have a fourth property in addition to mass, charge and spin, as popular physics theories such as supersymmetry predict? Researchers from Germany, the Czech Republic and the USA want to find the answer to this ...

Invisible particles 'seen' for the first time

A new optical effect in nanoscale disks of silicon, namely patterns of radiation that do not emit or scatter light, has been observed by A*STAR researchers and international collaborators. These modes, which have never before ...

Exotic new matter expected in ultracold atoms

(PhysOrg.com) -- Just as NASA engineers test new rocket designs in computer studies before committing themselves to full prototypes, so physicists will often model matter under various circumstances to see whether something ...

Reaction rate of many molecules depends on their shape

Most molecules occur in several shapes, which may behave very differently. Using a sorting machine for molecules, a German–Swiss research team can now for the first time directly measure the various reaction rates of different ...
