Researchers create first quasiparticle Bose-Einstein condensate

Physicists have created the first Bose-Einstein condensate—the mysterious fifth state of matter—made from quasiparticles, entities that do not count as elementary particles but that can still have elementary-particle ...

'Material universe' yields surprising new particle

An international team of researchers has predicted the existence of a new type of particle called the type-II Weyl fermion in metallic materials. When subjected to a magnetic field, the materials containing the particle act ...

Physicists show standard 'quasiparticle' theory breaks down at 'quantum critical point'

A new study this week finds that "quantum critical points" in exotic electronic materials can act much like polarizing "hot button issues" in an election. Reporting in Nature, researchers from Rice University, two Max Planck ...

Chiral zero sound found in Weyl semimetals

A pair of researchers at the Hong Kong University of Science and Technology has found that a chiral zero sound (CZS) effect can be induced in Weyl semimetals. In their paper published in the journal Physical Review Letters, ...

'Fibonacci quasiparticle' could form basis of future quantum computers

(Phys.org)—Topological quantum computing (TQC) is a newer type of quantum computing that uses "braids" of particle tracks, rather than actual particles such as ions and electrons, as the qubits to implement computations. ...

Theoretical physicists probe the Majorana mystery

(Phys.org) -- With headlines proclaiming the discovery of the Higgs boson particle physics has captured the imagination of the world, particularly among those who dwell on the nature of the cosmos. But this is only one puzzle ...

Electrons with a "split personality"

Some electrons in a superconducting material behave as if they were in a conventional metal, others as in an unconventional one – depending on the direction of their motion.

Major step toward confirming the existence of the majorana particle

A NIMS MANA group theoretically demonstrated that the results of the experiments on the peculiar superconducting state reported by a Chinese research group in January 2015 prove the existence of the Majorana-type particles.
