Using quantum technology to constrain new particles

Yet-to-be discovered axions and axion-like particles may be the key to explaining some of the deepest puzzles of our universe, such as dark matter and charge-parity violation in strong interactions. Several recent theories ...

Intense laser light modifies the pairing of electrons

The quantum-mechanical exchange interaction between electrons, a consequence of the Pauli exclusion principle, can be specifically modified with intense infrared light fields on time scales of a few femtoseconds, as time-resolved ...

Demonstration of diamond nuclear spin gyroscope

In a new report now published in Science Advances, Andrey Jarmola and an international research team in physics and materials in the U.S. and Germany demonstrated the function of a rotation sensor based on the Nitrogen-14 ...

Engineers crack 58-year-old puzzle on way to quantum breakthrough

A happy accident in the laboratory has led to a breakthrough discovery that not only solved a problem that stood for more than half a century, but has major implications for the development of quantum computers and sensors.In ...

The first observation of the nuclear Barnett effect

The electronic Barnett effect, first observed by Samuel Barnett in 1915, is the magnetization of an uncharged body as it is spun on its long axis. This is caused by a coupling between the angular momentum of the electronic ...
