Scientists build world's most accurate atomic clock

Take a second and turn it into trillions of moments. Measure each one. That's how precisely an atomic clock at Singapore's Centre for Quantum Technologies (CQT) keeps time-and with record-setting accuracy, according to results published in Nature on Sept. 23.

Quantum device simulates matter popping into existence

A research team led by faculty at the Duke Quantum Center (DQC) has observed string-breaking dynamics related to particle-antiparticle formation on a quantum simulator, among the first such observations in quantum physics.

Could negative mass exist and be observed?

Unlike electric charge, as far as we know all mass is positive, and positive masses attract one another. Could negative mass exist, and if so, what would be the ramifications?

Pigeons' proposed inner-ear compass runs into a noise problem

A pigeon turning its head might seem an unlikely electricity generator. Yet one proposed explanation for the bird's magnetic sense depends on exactly that: Turning through Earth's magnetic field would produce tiny electrical signals inside its ears. However, a theoretical study suggests that this miniature generator...

The secret to a perfect crystal may be a precisely calibrated extra turn

Creating a perfect crystal sounds straightforward: Arrange identical building blocks into a repeating, orderly structure. At the microscopic scale, though, even subtle biases in how particles interact can push them in preferred directions, making it harder to form uniform crystalline materials.

Light beam 'swims' upstream through a quantum fluid by violating Newton's third law

Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons work similarly. To move against a stream of light, an object or particle, like a photon, must...
