A new method for shaping matter into complex shapes, with the use of ‘twisted’ light, has been demonstrated in research at the University of Strathclyde. When atoms are cooled to temperatures close to absolute zero (-273°C), they stop behaving like particles and start to behave like waves. Atoms in this condition, which are known as ...
Researchers from the Institute of Laser Physics at Universität Hamburg have succeeded for the first time in realizing a time crystal that spontaneously breaks continuous time translation symmetry. They report their observation in a study published online by the journal Science. What is a time crystal? The idea of a time crystal goes back to ...
A single “super photon” made up of many thousands of individual light particles — about 10 years ago, researchers at the University of Bonn produced such an extreme aggregate state for the first time and presented a completely new light source. The state is called optical Bose-Einstein condensate and has captivated many physicists ever since, ...
