Chemical Uniformity May Help Astronomers Find Sun's Long-Lost Siblings

Chemical Uniformity May Help Astronomers Find Sun's Long-Lost Siblings

The chemical uniformity of stars in the same cluster is the result of turbulent mixing in the clouds of gas where star formation occurs, according to a study by astrophysicists at the University of California, Santa Cruz. [More]
Summer Graduate School on ‘Symmetries and Fundamental Interactions’ to be Held near the Bavarian Alps

Summer Graduate School on ‘Symmetries and Fundamental Interactions’ to be Held near the Bavarian Alps

The venue for the 2014 Summer Graduate School "Symmetries and Fundamental Interactions" will be the Frauenwörth Abbey near the Bavarian Alps. [More]
Quantum Photonics Researchers Develop Single-Photon Cannon

Quantum Photonics Researchers Develop Single-Photon Cannon

Electronic circuits are based on electrons, but one of the most promising technologies for future quantum circuits are photonic circuits, i.e. circuits based on light (photons) instead of electrons. [More]
Innovative Quantum Technique Generates Images with Undetected Photons

Innovative Quantum Technique Generates Images with Undetected Photons

Researchers from the Institute for Quantum Optics and Quantum Information (IQOQI), the Vienna Center for Quantum Science and Technology (VCQ), and the University of Vienna have developed a fundamentally new quantum imaging technique with strikingly counterintuitive features. [More]
Global Network of Radio Telescopes Accurately Measure Distance to Pleiades Star Cluster

Global Network of Radio Telescopes Accurately Measure Distance to Pleiades Star Cluster

Astronomers have used a worldwide network of radio telescopes to resolve a controversy over the distance to a famous star cluster -- a controversy that posed a potential challenge to scientists' basic understanding of how stars form and evolve. The new work shows that the measurement made by a cosmic-mapping research satellite was wrong. [More]
Rare Piece of Dense Solar Filament Material Discovered in Coronal Mass Ejection

Rare Piece of Dense Solar Filament Material Discovered in Coronal Mass Ejection

A space weather storm from the sun engulfed our planet on Jan. 21, 2005. The event got its start on Jan. 20, when a cloud of solar material, a coronal mass ejection or CME, burst off the sun and headed toward Earth. When it arrived at our planet, the ring current and radiation belts surrounding Earth swelled with extra particles, while the aurora persisted for six hours. [More]
Formation of Radioactive Cobalt Detected During Supernova Explosion

Formation of Radioactive Cobalt Detected During Supernova Explosion

A group of astrophysicists, including researchers from MIPT, have detected the formation of radioactive cobalt during a supernova explosion, lending credence to a corresponding theory of supernova explosions. Details are given in the journal Nature, one of the most cited scientific publications in the world. [More]
Weak Measurement and Compressive Sensing Combined to Measure High-Dimensional Quantum State

Weak Measurement and Compressive Sensing Combined to Measure High-Dimensional Quantum State

The result of every possible measurement on a quantum system is coded in its wave function, which until recently could be found only by taking many different measurements of a system and estimating a wave function that best fit all those measurements. [More]
Solar Energy Directly Measured at the Instant of Production

Solar Energy Directly Measured at the Instant of Production

For the first time ever, solar energy has been directly measured at the very instant it is produced. A world-first experiment carried out with the Borexino detector has observed, almost in real time, the flux of low-energy neutrinos emitted by the Sun, and shown that solar activity has hardly changed at all for over a hundred thousand years.

Scientists Realize Efficient Spin-Charge Converter Based on Common Semiconductor

Scientists Realize Efficient Spin-Charge Converter Based on Common Semiconductor

An international team of scientists including physicist Jairo Sinova from the University of Mainz realises a tunable spin-charge converter made of GaAs. These results have recently been published in the journal Nature Materials. [More]
Spitzer Space Telescope Spots Huge Eruption of Dust Around Star NGC 2547-ID8

Spitzer Space Telescope Spots Huge Eruption of Dust Around Star NGC 2547-ID8

NASA's Spitzer Space Telescope has spotted an eruption of dust around a young star, possibly the result of a smashup between large asteroids. This type of collision can eventually lead to the formation of planets. [More]
Electrons Mediate Antiferromagnetic Spin-Spin Interactions in Superconductors

Electrons Mediate Antiferromagnetic Spin-Spin Interactions in Superconductors

JQI Fellow Jay Sau, in collaboration with physicists from Harvard and Yale, has been studying the effects of embedding magnetic spins onto the surface of a superconductor. They recently report in paper that was chosen as an "Editor's Suggestion" in Physical Review Letters, that the spins can interact differently than previously thought. [More]
Physicists Directly Detect Neutrinos Created by 'Keystone' Proton-Proton Fusion Process

Physicists Directly Detect Neutrinos Created by 'Keystone' Proton-Proton Fusion Process

Using one of the most sensitive neutrino detectors on the planet, an international team of physicists including Andrea Pocar, Laura Cadonati and doctoral student Keith Otis at the University of Massachusetts Amherst report in the current issue of Nature that for the first time they have directly detected neutrinos created by the "keystone" proton-proton (pp) fusion process going on at the sun's core.

Scientists Reproduce Nucleosynthesis of Lithium

Scientists Reproduce Nucleosynthesis of Lithium

The field of astrophysics has a stubborn problem and it's called lithium. The quantities of lithium predicted to have resulted from the Big Bang are not actually present in stars. But the calculations are correct – a fact which has now been confirmed for the first time in experiments conducted at the underground laboratory in the Gran Sasso mountain in Italy. [More]
Researchers Successfully Detect Gamma-Ray Lines

Researchers Successfully Detect Gamma-Ray Lines

The extraordinary brightness and regularity of their light curves in the visible spectral range make type Ia supernovae valuable standardizable light sources, commonly used in modern cosmology. However, it has not yet been possible to directly measure these stellar explosions in their primary gamma radiation. [More]
