Pure Spin Current Could Help Detect Magnetic Fluctuations

Electrons have two degrees of freedom, or attributes: charge and spin. With the development of microfabrication technology in recent years, through the active combination of these two attributes, it has become possible to create devices that are head and shoulders above electronics of the past.

Phonon and Photon Share Common Properties

A research group at Osaka University has succeeded in observing at the intended timing two-phonon quantum interference by using two cold calcium ions in ion traps, which spatially confine charged particles. A phonon is a unit of vibrational energy that arises from oscillating particles within crystals. Two-particle quantum interference experiments using two photons or atoms have been previously reported, but this group’s achievement is the world’s first observation using two phonons.

Astrophysicists Obtain Precise Measurements for Orbiting Object in Einstein’s Cross Quasar

Spanish astrophysicists obtain precise measurements for an object orbiting a black hole five billion lightyears away. This is like detecting the ridges of a one euro coin located 100,000 kilometres away.

Material Rotating Around Young Protostar Could Have Dragged in Twisted Magnetic Fields

Using new images that show unprecedented detail, scientists have found that material rotating around a very young protostar probably has dragged in and twisted magnetic fields from the larger area surrounding the star. The discovery, made with the National Science Foundation's Karl G. Jansky Very Large Array (VLA) radio telescope, has important implications for how dusty disks -- the raw material for planet formation -- grow around young stars.

Japanese Scientists Unlock Mystery Behind Auroral Breakup

Auroras are dimly present throughout the night in polar regions, but sometimes these lights explode in brightness. Now Japanese scientists have unlocked the mystery behind this spectacle, known as auroral breakup.

Black Holes Could Swell to 50 Billion Times the Mass of the Sun

Black holes at the heart of galaxies could swell to 50 billion times the mass of the sun before losing the discs of gas they rely on to sustain themselves, according to research at the University of Leicester.

Major Advance in Proof of Existence of Majorana-Type Particle

A NIMS MANA group theoretically demonstrated that the results of the experiments on the peculiar superconducting state reported by a Chinese research group in January 2015 prove the existence of the Majorana-type particles.

Two Materials with Unusual Quantum-Mechanical Properties Connected Through Quantum Constriction

Work of physicists at the University of Geneva (UNIGE), Switzerland, and the Swiss Federal Institute of Technology in Zurich (ETH Zurich), in which they connected two materials with unusual quantum-mechanical properties through a quantum constriction, could open up a novel path towards both a deeper understanding of physics and future electronic devices. Their results have just been published in the journal Science.

Dynamic Version of Quantum Hall Effect Realized in Optical Superlattices

The transport of particles is usually induced by applying an external gradient to a system. Water, for example, flows down a slope and electric current is generated by applying a voltage. But already in ancient times another way of generating a directional motion was known: by periodic modulation of a system, as can be seen in the famous Archimedes' screw.
