Abstract: Number of detected atoms and contrast of Ramsey fringe are critical operation parameters in an atomic fountain clock. To optimize these operation parameters, a Monte Carlo method is utilized ...
Research suggests some metals’ semicore electrons may be more active on Earth’s surface than previously thought.
You probably learned in high school chemistry class that core electrons don't participate in chemical bonding.
Abstract: This article investigates the influence of high-energy secondary electrons on a Ka-band TM03 relativistic backward-wave oscillator (RBWO) using the particle-in-cell (PIC) simulation code ...
Caltech trapped 6,100 cesium atoms as qubits, the largest neutral-atom quantum system to date. Qubits stayed coherent for 13 seconds with 99.98% operational accuracy, defying scaling trade-offs. The ...
