In recent years, physicists have been trying to attain the control of chemical reactions in the quantum degenerate regime, where de Broglie wavelength of particles becomes comparable to the spacing between them. Theoretical ...
A team of computer and electrical engineers at the University of California, Santa Barbara, working with several colleagues from California Institute of Technology and another pair from Anello Photonics has developed a first-of-its-kind ...
Newly developed atomic engineering techniques have opened exciting opportunities for enabling ferroelectric behavior in high-k dielectrics, materials that have a high dielectric constant (i.e., kappa or k) compared to silicon. ...
Nearly every material, whether it is solid, liquid, or gas, expands when its temperature goes up and contracts when its temperature goes down. This property, called thermal expansion, makes a hot air balloon float, and the ...
A research group from the National Time Service Center of the Chinese Academy of Sciences has developed a hybrid high-stability atomic spin oscillator based on a Rb-Xe atomic comagnetometer. The research was published in ...
Researchers at the National Institute of Standards and Technology (NIST) have devised a photonic circuit on a chip that transforms a single incoming beam of laser light into a panoply of new beams, each with a host of different ...
Can dark matter interact with photons and influence atomic structure? A case for optical atomic clocks: Two different types of such clocks were compared at the Physikalisch-Technische Bundesanstalt (PTB) within the scope ...
A new type of miniature atomic clock could provide better timing over the span of weeks and months compared with current systems. Researchers at the National Institute of Standards and Technology (NIST), in collaboration ...
A new tool for generating microwave signals could help propel advances in wireless communication, imaging, atomic clocks, and more.
Last year, scientists drove up Mauna Loa volcano on Hawai'i, aimed a laser at a reflector positioned on Haleakala peak on Maui, and beamed rapid pulses of laser light through 150 kilometers of turbulent air. While the pulses ...
