A New Method to Measure the Quintessential Properties of Spin Waves in Graphene

Spin waves, a change in electron spin that propagates through a material, could fundamentally change how devices store and carry information.

Researchers Move Closer to Developing an Optical Atomic Clock with Highly Charged Ions

Laser beams can do more than just heat things up; they can cool them down too. That is nothing new for physicists who have devoted themselves to precision spectroscopy and the development of optical atomic clocks.

New Perspective Details Quantum Interference in Molecular Collisions

Quantum interference (QI), which relies on the wave-particle duality of microscopic particles, significantly affects the dynamics of energy transfer and chemical reactions induced by molecular collisions.

Einstein's Theory Passes Rigorous 16-year Tests

An international team has used telescopes around the world, including CSIRO’s Parkes radio telescope – Murriyang, to complete the most challenging tests yet of Einstein’s general theory of relativity.

Researchers Spot Young Stars at the Center of Milky Way Galaxy

What was formerly believed to be a gas and dust cloud at the center of the galaxy essentially comprises three very young stars. That is the finding of a new study carried out by researchers from the University of Cologne’s Institute of Astrophysics.

Research Demonstrates the Caustics in Atom Lasers

Cooled to almost absolute zero, atoms not only move in waves like light but also can be focused into shapes called caustics, similar to the reflecting or refracting patterns light makes on the bottom of a swimming pool or through a curved wine glass.

Researchers Redefine Energy to Explain Black Holes

Einstein was no stranger to mathematical challenges. He struggled to define energy in a way that acknowledged both the law of energy conservation and covariance, which is general relativity's fundamental feature where physical laws are the same for all observers.
