Spooky quantum particle pairs fly like weird curveballs
Curvy baseball pitches have surprising things in common with quantum particles described in a new physics study, though the latter fly much more weirdly.

New quantum computer design to predict molecule properties
The standard approach to building a quantum computer with majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing—quantum chemistry—would require these qubits ...
'Orbital-selective pairing' theory applied to first 'heavy fermion' superconductor
A 2017 theory proposed by Rice University physicists to explain the contradictory behavior of an iron-based high-temperature superconductor is helping solve a puzzle in a different type of unconventional superconductor, the ...
Scientists uncover how to stop cyber intrusions
U.S. Army-funded researchers at the University of California in Los Angles have found a proverbial smoking gun signature of the long sought-after Majorana particle, and the find, they say, could block intruders on sensitive ...
Thermoelectric nanodevice based on Majorana fermions is proposed
In March 1938, the young Italian physicist Ettore Majorana disappeared mysteriously, leaving his country's scientific community shaken. The episode remains unexplained, despite Leonardo Scascia's attempt to unravel the enigma ...
Exotic material exhibits an optical response in enormous disproportion to the stimulus
No earlier theory had envisioned that the responses would be so large! Scientists "poked" three crystals with pulses of light. Unexpectedly, the crystals exhibited the largest nonlinear optical response of any known crystal. ...
Unconventional superconductor may be used to create quantum computers of the future
With their insensitivity to decoherence, Majorana particles could become stable building blocks of quantum computers. The problem is that they only occur under very special circumstances. Now, researchers at Chalmers University ...
Current generated when light hits a material reveals electrons behaving like an elusive particle
A massless particle, a.k.a. Weyl fermion, predicted nearly 100 years ago, has been found in another corner of physics. Electrons in a semimetal can behave like these particles. They are either right-handed or left-handed—they ...
Weyl particles detected in strongly correlated electron systems
At TU Wien recently, particles known as 'Weyl fermions' were discovered in materials with strong interaction between electrons. Just like light particles, they have no mass but nonetheless they move extremely slowly.
Physicists find evidence of an exotic state of matter
Using ultracold atoms, researchers at Heidelberg University have found an exotic state of matter where the constituent particles pair up when limited to two dimensions. The findings from the field of quantum physics may hold ...
