Neutrinos, atomic clocks and an experiment to detect a time dilation

Griffith University researchers are conducting an experiment at ANSTO that will test a revolutionary physics theory that time reversal symmetry-breaking by neutrinos might cause a time dilation at the quantum scale.

A new class of superconductors

A new theory that could explain how unconventional superconductivity arises in a diverse set of compounds might never have happened if physicists Qimiao Si and Emilian Nica had chosen a different name for their 2017 model ...

Physicists get closer to examining the symmetries underlying our universe

Every field has its underlying principles. For economics it's the rational actor; biology has the theory of evolution; modern geology rests on the bedrock of plate tectonics.

Looking for dark matter near neutron stars with radio telescopes

In the 1970s, physicists uncovered a problem with the Standard Model of particle physics—the theory that describes three of the four fundamental forces of nature (electromagnetic, weak, and strong interactions; the fourth ...

Ideal type-II Weyl points are observed in classical circuits

The elementary particles that build the universe have two types: bosons and fermions, where the fermions are classified as Dirac, Weyl, and Majorana fermions. In recent years, Weyl fermions are found in condensed matter systems, ...

Topological mechanical metamaterials go beyond Newton's third law

A change in perspective can work wonders. This has been especially true with respect to the paradigms for explaining material properties using the concept of topology, "ideas that are currently revolutionizing condensed matter ...

Going beyond the anti-laser may enable long-range wireless power transfer

Ever since Nikola Tesla spewed electricity in all directions with his coil back in 1891, scientists have been thinking up ways to send electrical power through the air. The dream is to charge your phone or laptop, or maybe ...

Antiferromagnets are suitable for dissipationless nanoelectronics, contrary to current theories

Sometimes combinations of different things produce effects that no one expects, such as when completely new properties appear that the two combined parts do not have on their own. Dr. Libor Šmejkal from Johannes Gutenberg ...

New 'genomic' method reveals atomic arrangements of battery material

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory, Stony Brook University (SBU), the Materials Project at DOE's Lawrence Berkeley National Laboratory (Berkeley Lab), the University of California, ...

Scientists achieve higher precision weak force measurement between protons, neutrons

Through a one-of-a-kind experiment at the Department of Energy's Oak Ridge National Laboratory, nuclear physicists have precisely measured the weak interaction between protons and neutrons. The result quantifies the weak ...
