Physicists still divided about quantum world, 100 years on
Quantum mechanics have led to the development of vast amounts of tech, such as lasers or transistors used phones. The theory of quantum mechanics has transformed daily life since being…
From thousands of defects, one magnesium oxide qubit emerges as a quantum contender
Magnesium atoms (orange) and oxygen atoms (red) surround the nitrogen-vacancy center in magnesium oxide, shown by a transparent representation of a nitrogen atom under the missing magnesium atom. The yellow…
Simulating the Hawking effect and other quantum field theory predictions with polariton fluids
The central data of the paper. (a) The phase of the fluid (retrieved by interferometry) and in (b) the corresponding fluid velocity (solid line) for three different configurations as well…

Physicists show tensor mesons play important role in light-on-light scattering
Light is scattered by light—via virtual particles. Credit: Vienna University of Technology Usually, light waves can pass through each other without any resistance. According to the laws of electrodynamics, two…
Physicists discover new state of quantum matter
Credit: CC0 Public Domain Researchers at the University of California, Irvine have discovered a new state of quantum matter. The state exists within a material that the team reports could…
Researchers uncover a topological excitonic insulator with a tunable momentum order
Artistic illustration of a topological exciton insulator: Excitons condense in the bulk of the material, forming a collective insulating phase, while topologically protected edge modes propagate freely along the sample’s…
