SLAC Scientists View Ultrafast Snapshots of Light-Driven Superconductivity

April 18, 2014

0 Comments

Scientists at SLAC National Accelerator Laboratory’s Linac Coherent Light Source used carefully timed pairs of laser pulses to capture ultrafast snapshots of light-driven superconductivity. A new study pins down a major factor behind the appearance of superconductivity – the ability to conduct electricity with 100 percent efficiency – in a promising copper-oxide material. Scientists used […]

Physicists Confirm Discovery of Four-Quark Hadron

April 14, 2014

1 Comment

The Large Hadron Collider beauty collaboration has confirmed the existence of exotic hadron with two quarks, two anti-quarks. Physicists in Syracuse University’s College of Arts and Sciences have helped confirm the existence of exotic hadrons — a type of matter that cannot be classified within the traditional quark model. Their finding is the subject of […]

Researchers Observe What Happens During a Quantum Phase Transition

April 7, 2014

0 Comments

In a newly published study, researchers observe what happens during a quantum phase transition, and compare the “quantum melting” of the magnetic structure with the classical “thermal melting” phase transition. When ice is warmed, the water molecules forming its structure vibrate more and more vigorously until finally the forces between them are no longer strong […]

Researchers Entangle Two Independent Photons with Different Frequencies

April 2, 2014

0 Comments

Using time-resolved measurement and active feed forward, researchers from the University of Science and Technology of China have entangled two independent photons of different colors for the first time. Entanglement has been capturing the imagination of scientists as well as the public ever since it first emerged from the newly minted quantum mechanics formalism eight […]

Nanoparticle Temporarily Violates the Second Law of Thermodynamics

March 31, 2014

2 Comments

In a newly published study, an international team of researchers detail how they discovered that a nanoparticle trapped with laser light temporarily violates the second law of thermodynamics. Objects with sizes in the nanometer range, such as the molecular building blocks of living cells or nanotechnological devices, are continuously exposed to random collisions with surrounding […]

New System Filters Light Waves Based on Direction

March 28, 2014

0 Comments

Researchers from MIT have produced a system that allows light of any color to pass through only if it is coming from one specific angle. Light waves can be defined by three fundamental characteristics: their color (or wavelength), polarization, and direction. While it has long been possible to selectively filter light according to its color […]

Third Law of Thermodynamics Restored in Thin Films of Spin Ice

March 12, 2014

1 Comment

A newly published study reveals that the Third Law of Thermodynamics can be restored in thin films of the magnetic material spin ice. Thin films of spin ice have been shown to demonstrate surprising properties which could help in the development of applications of magnetricity, the magnetic equivalent of electricity. Published today in Nature Communications, […]

New Analyses May Imply the Existence of a Dark Matter Particle

March 11, 2014

0 Comments

At a recent physics symposium, scientists from around the world presented several analyses that may imply the existence of a dark matter particle. Dark matter, the mysterious substance estimated to make up approximately more than one-quarter of the mass of the universe, is crucial to the formation of galaxies, stars and even life but has […]

Using “Multiferroics” Researchers Make Major Improvements in Computer Processing

March 6, 2014

0 Comments

A team of UCLA researchers has demonstrated that using an emerging class of magnetic materials called “multiferroics” to generate spin waves could reduce wasted heat and increase power efficiency for computer processing by up to 1,000 times. Have you ever wondered why your laptop or smartphone feels warm when you’re using it? That heat is […]

Researchers Combine Excited States of Two Materials into a New Quantum Mechanical State

March 3, 2014

0 Comments

A team of researchers has taken the excited states of two principally different materials and combined them into a new quantum mechanical state that shares their best properties. Ann Arbor — Like a spring connecting two swings, light can act as photon glue that binds together the quantum mechanical properties of two vastly different materials. […]

High-Precision Measurement of the Electron is More Precise by a Factor of 13

February 28, 2014

0 Comments

Physicists from the Max Planck Institute have achieved a high-precision measurement of the atomic mass of the electron, 13 times more precise than previously known. Electrons are the quantum glue of our world. Without electrons there would be no chemistry, and light would be unable to interact with matter. If electrons were only a little […]
