Revisiting the history of the CPT theorem

A new review looks at an important and often overlooked aspect of physics that suggested symmetry in the particle zoo and how it could be broken.

A quantum drum that stores quantum states for record-long times

Researchers at the Niels Bohr Institute, University of Copenhagen, have improved the coherence time of a previously developed quantum membrane dramatically. The improvement will expand the usability of the membrane for a ...

Fusion experts tackle cooling strategies for fusion fuel cycle

To achieve practical energy from fusion, extreme heat from the fusion system "blanket" component must be extracted safely and efficiently. Oak Ridge National Laboratory fusion experts are exploring how tiny 3D-printed obstacles ...

Developing next-generation superconducting cables

Researchers at Florida State University's Center for Advanced Power Systems (CAPS), in collaboration with Colorado-based Advanced Conductor Technologies, have demonstrated a new, ready-to-use superconducting cable system—an ...

Scientists use quantum computers to simulate quantum materials

Quantum computers promise to revolutionize science by enabling computations that were once thought impossible. But for quantum computers to become an everyday reality, there is a long way to go with many challenging tests ...

Diamond mirrors for high-powered lasers

Just about every car, train and plane that's been built since 1970 has been manufactured using high-power lasers that shoot a continuous beam of light. These lasers are strong enough to cut steel, precise enough to perform ...

Making racetrack noise bearable with physics

Although racetracks can be fun for communities, they usually come with very high levels of noise that can sour nearby neighborhoods to the experience.

Halting a wave in its tracks

Topological ideas have recently taken the center stage of modern electromagnetics. Typical topological photonic systems are based on nonreciprocal materials, a class of materials that enables asymmetric light–matter interactions. ...

Acoustic sensors to pinpoint shooters in an urban setting

During a gunshot, two sound events occur: the muzzle blast and the supersonic shock wave. Acoustic sensors, such as arrays of microphones, can capture these sounds and use them to approximate the location of a shooter.

Custom 'headphones' boost atomic radio reception 100-fold

Researchers at the National Institute of Standards and Technology (NIST) have boosted the sensitivity of their atomic radio receiver a hundredfold by enclosing a small glass cylinder of cesium atoms inside what looks like ...

Mixing laser beams and X-ray beams

Unlike fictional laser swords, real laser beams do not interact with each other when they cross—unless the beams meet within a suitable material allowing for nonlinear light-matter interaction. In such a case, wave mixing ...
