Physicists Confirm Discovery of Four-Quark Hadron

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

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 […]

New System Could Provide First Method for Filtering Light Waves Based on Direction

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 […]

Photon Glue Enables a New Quantum Mechanical State

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. […]

Precise Measurement of Electron Mass

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 […]

Scientists Find New Path to Loss-Free Electricity

Using advanced electron diffraction techniques, researchers obtained direct experimental evidence of the subtle changes in electron orbitals by comparing an unaltered, non-superconducting material with its doped, superconducting twin. Armed with just the right atomic arrangements, superconductors allow electricity to flow without loss and radically enhance energy generation, delivery, and storage. Scientists tweak these superconductor recipes […]

Solotronics Electronics Operating on a Single Atom Level

Researchers at the University of Warsaw have created and studied two new types of solotronic structures, including the world’s first quantum dots containing single cobalt ion. Electronic systems operating on the level of individual atoms would seem to be the natural consequence of efforts to achieve ever-greater miniaturization. Already now, we are able to control […]

Study Reveals the Possibility of Cloning Quantum Information from the Past

A newly published study shows that it is possible to clone quantum information from the past, allowing for a particle, or a time traveler, to make multiple loops back in time. Popular television shows such as “Doctor Who” have brought the idea of time travel into the vernacular of popular culture. But problem of time […]
