Ultra-thin designer materials unlock quantum phenomena

A team of theoretical and experimental physicists have designed a new ultra-thin material that they have used to create elusive quantum states. Called one-dimensional Majorana zero energy modes, these quantum states could ...

Are primordial magnetic field theories getting in a twist?

In cosmic voids where the density of galaxies is far lower than standard, astronomers have observed weak magnetic fields that may provide a window into the early universe. The fields 10-17-10-10 G in magnitude with large ...

Physicists capture the sound of a 'perfect' fluid

For some, the sound of a "perfect flow" might be the gentle lapping of a forest brook or perhaps the tinkling of water poured from a pitcher. For physicists, a perfect flow is more specific, referring to a fluid that flows ...

First-ever evidence of exotic particles in cobalt monosilicide

Anew study provides the first evidence of exotic particles, known as fourfold topological quasiparticles, in the metallic alloy cobalt monosilicide. Published in the Proceedings of the National Academy of Sciences, this comprehensive ...

Extremely rare Higgs boson decay process spotted

The Higgs boson reached overnight fame in 2012 when it was finally discovered in a jumble of other particles generated at CERN's Large Hadron Collider (LHC) in Geneva, Switzerland. The discovery was monumental because the ...

The observation of Bloch ferromagnetism in composite fermions

Composite fermions are exotic quasi-particles found in interacting 2-D fermion systems at relatively large perpendicular magnetic fields. These quasi-particles, which are composed of an electron and two magnetic flux quanta, ...

One theory beyond the standard model could allow wormholes that you could actually fly through

Wormholes are a popular feature in science fiction, the means through which spacecraft can achieve faster-than-light (FTL) travel and instantaneously move from one point in spacetime to another. And while the General Theory ...

Searching for Heavy Higgs bosons decaying into two tau leptons with the ATLAS detector

In particle physics, three out of the four known fundamental forces in the universe, namely electromagnetic, weak and strong interactions, are described by a theory known as the standard model (SM). One extension of this ...

CERN experiments announce first indications of a rare Higgs boson process

At the 40th ICHEP conference, the ATLAS and CMS experiments announced new results which show that the Higgs boson decays into two muons. The muon is a heavier copy of the electron, one of the elementary particles that constitute ...

Ferried across: Figuring out unconventional spin transport in quantum spin liquids

Scientists at Tokyo Institute of Technology (Tokyo Tech) and Yokohama National University (YNU) have uncovered the peculiar mechanism by which spin perturbations travel through a seemingly unpassable region of a quantum spin ...
