An Arizona-based company has launched its next generation of low-noise Chip-Scale Atomic Clock (CSAC). Microchip's model SA65-LN is designed to operate in a wider temperature range, enabling low-phase ...

Inside a laboratory nestled in the foothills of the Rocky Mountains, amid a labyrinth of lenses, mirrors, and other optical machinery bolted to a vibration-resistant table, an apparatus resembling a ...

Researchers demonstrated a new optical atomic clock that uses a single laser and doesn't require cryogenic temperatures. By greatly reducing the size and complexity of atomic clocks without ...

Scientists are building a nuclear clock so precise it could detect dark matter and test the laws of physics. The secret? A rare, low-energy transition in thorium-229. Here, we explain the science of ...
