High field magnet at BER II: Insight into a hidden order

Fri, 20 Oct 17 00:08:50 -0700

A specific uranium compound has puzzled researchers for thirty years. Although the crystal structure is simple, no one understands exactly what is happening once it is cooled below a certain temperature. Apparently, a 'hidden order' emerges, whose nature is completely unknown.Now physicists have characterised this hidden order state more precisely and studied it on a microscopic scale. To accomplish this, they utilised the High-Field Magnet at the HZB that permits neutron experiments to be conducted under conditions of extremely high magnetic fields.

How a neutron star collision proves Einstein's 100-year-old General Relativity prediction

Thu, 19 Oct 17 00:04:00 -0700

A hundred years ago, Albert Einstein published his General Relativity theory, predicting the existence of gravitational waves or ripples in space-time, due to violent motion of massive objects in the universe. Collision and merger of two neutron stars should produce gravitational waves and gamma rays simultaneously. Until a few weeks ago, that could not be proven scientifically. Then researchers saw the collision of two neutron stars on Aug. 17, 2017, and everything changed.
