A collaboration of US-based researchers has proposed a new type of detector that would measure sound waves caused by gravitational waves in the 0.1–1.5 kHz range. The system comprises several kilograms of superfluid helium-4 held in a cylindrical container that is coupled to microwaves in a superconductor resonator. Confinement in...

A research team has made the first direct visual observation and measurement of ultrafast vortex dynamics in superconductors. The technique used, detailed in the journal Nature Communications, could contribute to the development of novel practical applications by optimizing superconductor properties for use in electronics, according to the scientists.

The Large Hadron Collider, with its 17-mile circumference, is definitely large, but the latter fraction of its name is a little misleading. That’s because what collides in the LHC are the tiny pieces inside the hadrons, not the hadrons themselves.

In a series of lab experiments on exotic materials, scientists from the University of California and Stanford University have discovered "firm evidence" of particles that are their own antiparticles. Physicists have been looking for such Majorna fermions since physicist Ettore Majorana predicted them in 1937. The result is currently more...

Researchers from the LHCb experiment at CERN reported the observation of a new particle from the baryon family. It contains two charm quarks and one up quark. The mass of the newly identified particle is about 3621 MeV, almost four times heavier than the most familiar baryon, the proton, a...

NIST researchers have developed an automated probe system to evaluate computer components submitted by both private sector and federal labs to the Cryogenic Computing Complexity (C3) program. C3 aims to enable a new generation of low-power superconducting supercomputers that operate at liquid helium temperatures and use ultra-fast switching of microscopic...
