'Swing-Dancing' Pairs of Electrons Discovered

May 13, 2015 — Scientists have discovered electrons that can 'swing dance.' This unique electronic behavior can potentially lead to new families of quantum ... read more

May 13, 2015 — Physicists have built a microscope that is able to see up to 1,000 individual fermionic atoms. The researchers devised a laser-based technique to trap and freeze fermions in place, and image the ... read more

Detection of Spin of Atoms at Room Temperature Theoretically Demonstrated

May 12, 2015 — For the first time, a researcher has theoretically demonstrated that it is possible to detect a single nuclear spin at room temperature, which could pave the way for new approaches to medical ... read more

May 12, 2015 — Topological insulators are "strange" materials, insulators on the inside and conductors on the surface. They also have properties that make them excellent candidates for the development of ... read more

May 11, 2015 — Rydberg atoms, atoms whose outermost electrons are highly excited but not ionized, might be just the thing for processing quantum information. These outsized atoms can be sustained for a long time in ... read more

May 7, 2015 — Researchers have succeeded in creating a new 'whispering gallery' effect for electrons in a sheet of graphene -- making it possible to precisely control a region that reflects electrons ... read more

May 7, 2015 — Scientists have found a way to control heat propagation in photonic nano-sized devices, which will be used for high speed communications and quantum information ... read more

May 7, 2015 — Researchers have discovered a novel way of combining plasmonic and magneto-optical effects. They experimentally demonstrated that patterning of magnetic materials into arrays of nanoscale dots can ... read more

May 6, 2015 — Scientists have discovered topologically protected 1-D electron conducting channels at the domain walls of bilayer graphene that should prove useful for ... read more

May 5, 2015 — Quantum computers are in theory capable of simulating the interactions of molecules at a level of detail far beyond the capabilities of even the largest supercomputers today. Such simulations could ... read more

Defects in Atomically Thin Semiconductor Emit Single Photons

May 4, 2015 — Researchers have shown that defects on an atomically thin semiconductor can produce light-emitting quantum dots. The quantum dots serve as a source of single photons and could be useful for the ... read more

First Quantum Evidence of System-Shrinking Negative Electronic Compressibility in Novel Insulator

Apr. 27, 2015 — Add water to a half-filled cup and the water level rises. This everyday experience reflects a positive material property of the water-cup system. But what if adding more water lowers the water level ... read more

Apr. 30, 2015 — A quantum state predicted by the Russian theoretician Vitaly Efimov 40 years ago has been discovered by physicists in a molecule consisting of three helium atoms. The molecule is of enormous spatial ... read more

Apr. 30, 2015 — Researchers have experimentally identified a pointlike monopole in a quantum field for the first time. The discovery gives scientists insight into the monopole magnet, an elementary particle that ... read more

Quantum Particles at Play: Game Theory Elucidates the Collective Behavior of Bosons

Apr. 28, 2015 — Quantum particles behave in strange ways and are often difficult to study experimentally. Using mathematical methods drawn from game theory, physicists have shown how bosons, which like to enter the ... read more

When Mediated by Superconductivity, Light Pushes Matter Million Times More

Apr. 28, 2015 — When a mirror reflects light, it experiences a slight push. This radiation pressure can be increased considerably with the help of a small superconducting island. The finding paves a way for the ... read more

Apr. 27, 2015 — The 'holographic principle,' the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange ... read more

Apr. 23, 2015 — Thermal imaging, microscopy and ultra-trace sensing could take a quantum leap with a new technique. Scientists used quantum correlated beams of light to overcome the fundamental detection limit of ... read more

Reducing Big Data Using Ideas from Quantum Theory Makes It Easier to Interpret

Apr. 23, 2015 — Analysing the large volumes of data gathered by modern businesses and public services is problematic. Traditionally, relationships between the different parts of a network have been  represented  ... read more
