A diagram of the electron energy levels of Rubidium. Two of the energy level gaps match the frequencies of optical photons and microwave photons, respectively. Lasers are used to force the electron to ...

Researchers have discovered a way to "translate" quantum information between different kinds of quantum technologies, with significant implications for quantum computing, communication, and networking ...

Energy transfer is systematically reviewed as a guiding principle for current materials and optimization strategies in perovskite solar cells. Characteristic mechanisms are identified to classify ...

Scientists use European XFEL's fast X-ray pulses for doubly resonant ionisation of krypton. (Nanowerk News) Speed matters. When an X-ray photon excites an atom or ion, making a core electron jump onto ...

Scientists at TU Wien found that electrons need specific “doorway states” to escape solids, not just energy. The insight explains long-standing anomalies in experiments and unlocks new ways to ...
