Repulsive photons

Light particles normally do not "feel" each other because there is no interaction acting between them. Researchers at ETH have now succeeded in manipulating photons inside a semiconductor material in such a way as to make ...

Neutrons zero in on the elusive magnetic Majorana fermion

Neutron scattering has revealed in unprecedented detail new insights into the exotic magnetic behavior of a material that, with a fuller understanding, could pave the way for quantum calculations far beyond the limits of ...

New quantum memory stores information for hours

Storing information in a quantum memory system is a difficult challenge, as the data is usually quickly lost. At TU Wien, ultra-long storage times have now been achieved using tiny diamonds.

Going solid-state could make batteries safer and longer-lasting

If you pry open one of today's ubiquitous high-tech devices—whether a cellphone, a laptop, or an electric car—you'll find that batteries take up most of the space inside. Indeed, the recent evolution of batteries has ...

A new state of matter: Quantum spin liquids explained

Magnetism is one of the oldest recognised material properties. Known since antiquity, records from the 3rd century BC describe how lodestone, a naturally occurring magnetised ore of iron, was used in primitive magnetic compasses. ...
