### Magic numbers of quantum matter revealed by cold atoms

Topology, a branch of mathematics classifying geometric objects, has been exploited by physicists to predict and describe unusual quantum phases: the topological states of matter. These intriguing phases, ...

### Fractional quantum Hall effect: Experimental progress and quantum computing applications

The Hall effect, discovered in 1879, is observable when a Hall voltage perpendicular to the current is produced across a conductor under a magnetic field. Although the Hall effect was discovered in a sheet ...

### Nanoscale neighbors: First use of transformation optics to accurately analyze nonlocality in 3D plasmonic systems

(Phys.org) —The ubiquitous van der Waals interaction – a consequence of quantum charge fluctuations – includes intermolecular forces such as attraction and repulsion between atoms, molecules and su ...

### Xinwen Zhu discusses the unifying theory of mathematics

In 1994, British mathematician Andrew Wiles successfully developed a proof for Fermat's last theorem—a proof that was once partially scribbled in a book margin by 17th-century mathematician Pierre de Fermat ...

### Vortex of electrons provides unprecedented information on magnetic quantum states in solids

Electron states in solids are responsible for many material properties, such as color and electrical conductivity. However, because of their confinement within the crystal, it is very difficult to study the ...
