Topological protection in mechanical metamaterials
Researchers at Leiden University, the Netherlands, showed that certain crystal defects in mechanical metamaterials can harbour topologically protected motions. These mechanical states are analogues of protected ...
Magnetic bubbles behave differently than other magnetic defects (w/ video)
Graphene-boron mix shows promise for lithium-ion batteries
Frustration led to revelation when Rice University scientists determined how graphene might be made useful for high-capacity batteries.
Cosmology in the lab using laser-cooled ions
Scientists would love to know which forces created our universe some 14 billion years ago. How could – due to a breaking of symmetry – matter, and thus stars and galaxies, be created from an originally ...
Searching for defects in space
Topological defects in space may have developed fractions of a second after the Big Bang. Simulations of these wormlike entities and a comparison of the simulations with cosmic background radiation measurements ...
