No Evidence Found for Existence of Majorana Neutrinos

The Majorana nature of neutrinos and the neutrinoless double-beta decay
Neutrinos are tiny, neutral elementary particles that, contrary to the standard model of physics, have been proven to have mass. One possible explanation for this mass could be that neutrinos are their own antiparticles, so-called Majorana particles.

Novel Method Utilizes Quantum Mechanical Vibrations for High Precision Measurements

At TU Vienna, a new method was developed to utilize quantum mechanical vibrations for high precision measurements; The well-known concept of the Ramsey interferometer is applied to a complex multi particle system consisting of hundreds of atoms

Rare, Intense Gamma-Ray Burst Travels for 12.1 Billion Years Before Reaching the Earth

Known as a gamma-ray burst, the rare, intense light captured in the night sky resulted from one of the biggest and hottest explosions in the universe, occurring shortly after the Big Bang

Scientists Detect First of Thorne-Zytkow Objects

In a discovery decades in the making, scientists have detected the first of a "theoretical" class of stars first proposed in 1975 by physicist Kip Thorne and astronomer Anna Zytkow. Thorne-Zytkow objects (TZOs) are hybrids of red supergiant and neutron stars that superficially resemble normal red supergiants, such as Betelguese in the constellation Orion. They differ, however, in their distinct chemical signatures that result from unique activity in their stellar interiors.

Spitzer Space Telescope Reveals Rare Example of Type Ia Supernova Explosion

Supernovas are often thought of as the tremendous explosions that mark the ends of massive stars' lives. While this is true, not all supernovas occur in this fashion. A common supernova class, called Type Ia, involves the detonation of white dwarfs -- small, dense stars that are already dead.

New Discovery May Help Develop Classification Scheme for Quantum Criticality

Quantum criticality, the strange electronic state that may be intimately related to high-temperature superconductivity, is notoriously difficult to study. But a new discovery of “quantum critical points” could allow physicists to develop a classification scheme for quantum criticality — the first step toward a broader explanation.

New Technique in Detecting Single Atoms in Optical Lattices Wins Otto Hahn Medal 2013

For his excellent doctoral thesis, the young physicist Manuel Endres has been awarded with the Otto Hahn Medal 2013. Since 1978 the Max Planck Society presents this honour annually to junior scientists for groundbreaking scientific achievements connected to their doctoral thesis. The award is intended to encourage highly talented people to decide for a career in fundamental research.

Ultraprecise Atomic Clock Installed at Atacama Large Millimeter/Submillimeter Array Operations Site

Scientists recently upgraded the Atacama Large Millimeter/submillimeter Array (ALMA) by installing an ultraprecise atomic clock at ALMA’s Array Operations Site, home to the observatory’s supercomputing correlator. This upgrade will eventually allow ALMA to synchronize with a worldwide network of radio astronomy facilities collectively known as the Event Horizon Telescope (EHT).
