Light Can Push Matter Million Times More with the Help of a Superconducting Island

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. This was revealed by the joint research done in the Aalto University and the Universities of Jyväskylä and Oulu.

Intermittent Explosive Bursts of Heat Behind the Mystery of Coronal Heating

The sun's surface is blisteringly hot at 10,340 degrees Fahrenheit -- but its atmosphere is another 300 times hotter. This has led to an enduring mystery for those who study the sun: What heats the atmosphere to such extreme temperatures? Normally when you move away from a hot source the environment gets cooler, but some mechanism is clearly at work in the solar atmosphere, the corona, to bring the temperatures up so high.

Swedish Physicist and Cosmologist Named Recipient of KTH Great Prize

Physicist and cosmologist Max Tegmark has been named the recipient of this year's Great Prize from Sweden's KTH Royal Institute of Technology. The MIT scientist earned his master's degree in engineering physics at KTH in 1990.

Using Game Theory Physicists Shown How Bosons Can Form Multiple Groups

Quantum particles behave in strange ways and are often difficult to study experimentally. Using mathematical methods drawn from game theory, physicists of Ludwig-Maximilias-Universitaet (LMU) in Munich have shown how bosons, which like to enter the same state, can form multiple groups.

Water Vapor Could Have Been Abundant in Space a Billion Years after the Big Bang

How soon after the Big Bang could water have existed? Not right away, because water molecules contain oxygen and oxygen had to be formed in the first stars. Then that oxygen had to disperse and unite with hydrogen in significant amounts.

First Proton Collisions at CERN to Take Place in June

First collisions of protons at the world's largest science experiment are expected to start the first or second week of June, according to a senior research scientist with CERN's Large Hadron Collider in Geneva.

New Planets Discovered by Detecting Wobble of HD 7924 Star

A team of astronomers using ground-based telescopes in Hawaiʻi, California and Arizona recently discovered a planetary system orbiting a nearby star that is only 54 light-years away. All three planets orbit their star at a distance closer than Mercury orbits the sun, completing their orbits in just 5, 15 and 24 days.

Special Spectroscopy Enables Direct Detection of Cyclotron Radiation from Individual Electrons

A year before Albert Einstein came up with the special theory of relativity, or E=mc2, physicists predicted the existence of something else: cyclotron radiation. Scientists predicted this radiation to be given off by electrons whirling around in a circle while trapped in a magnetic field. Over the last century, scientists have observed this radiation from large ensembles of electrons but never from individual ones.

Negative Electronic Compressibility Realized in 3D Material

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 by deforming the cup? This would mean a negative compressibility.

Astrophysicists Create 3D Map of Universe

Astrophysicists have created a 3D map of the universe that spans nearly two billion light years and is the most complete picture of our cosmic neighbourhood to date.

New Study Shows that Not All "Engine-driven" Supernova Explosions Cause Gamma-ray Bursts

Astronomers using the National Science Foundation's Very Large Array (VLA) have found a long-sought "missing link" between supernova explosions that generate gamma-ray bursts (GRBs) and those that don't.

Researchers Suggest that Holographic Principle Could Hold in Flat Spacetime

At first glance, there is not the slightest doubt: to us, the universe looks three dimensional. But one of the most fruitful theories of theoretical physics in the last two decades is challenging this assumption.

Research Shows How Heat is Converted to Spin Current in Magnetic Superconductors

Physicists have shown how heat can be exploited for controlling magnetic properties of matter. The finding helps in the development of more efficient mass memories. The result was published yesterday in Physical Review Letters. The international research group behind the breakthrough included Finnish researchers from the University of Jyväskylä and Aalto University.

Inelastic Neutron Scattering Experiments Reveal Coexistence of Superconductivity and Magnetism

Inelastic neutron scattering experiments on a copper-oxide superconductor reveal nearly static, spatially modulated magnetism. Because static magnetism and superconductivity do not like to coexist in the same material, the superconducting wave function is also likely modulated in space and phase-shifted to minimize overlap, consistent with recent theory.

New Mathematical Proof Reveals a Much Tighter Limit on How Fast Quantum Information Can Propagate

If you’re designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but JQI physicists have narrowed the theoretical limits for where that “speed limit” is. The work implies that quantum processors will work more slowly than some research has suggested.
