In principle, quantum-based devices such as computers and sensors could vastly outperform conventional digital technologies for carrying out many complex tasks. But developing such devices in practice...
确定水的含量和同位素组成对理解行星体的形成和演化具有重要意义。锆石是一种普遍存在于各类岩石中具有稳定的物理化学性质的副矿物,耐高温(1000℃)、耐机械磨蚀和化学腐蚀,且具有较低的扩散系数,因此被广泛应用于U–Pb定年、Li–O–Hf同位素体系以及Ti温度计等多种地球化学研究。此前,本研究课题组成功开发出利用二次离子质谱仪(Secondary ion mass spectroscopy, SIMS...
Researchers have used advanced electron microscopy (EM) technology to see how human viruses move in high resolution in a near-native environment. The visualization technique could lead to improved und...

By ricocheting neutrons off the atoms of yttrium manganite (YMnO3) heated to 3,000 degrees Fahrenheit, researchers have discovered the atomic mechanisms that give the unusual material its rare electro...
JILA physicists have created an entirely new design for an atomic clock, in which strontium atoms are packed into a tiny three-dimensional (3-D) cube at 1,000 times the density of previous one-dimensi...
The 49th Conference of the European Group on Atomic Systems (EGAS) will be held at Durham University in the United Kingdom from 17th to 21st July, 2017. EGAS is a division of the European Physical Soc...
Common sense might dictate that for an object to move from one point to another, it must go through all the points on the path.“Imagine someone driving from Kansas City to Topeka on I-70 — it’s safe t...
The Gordon Research Seminar on Atomic Physics is a unique forum for graduate students, post-docs, and other scientists with a similar level of experience and education to present, exchange, and discus...

The Atomic Physics Gordon Conference has a long history of bringing together top researchers and future leaders in the fields of atomic, molecular, and optical physics, and of reporting exciting recen...
JILA physicists have demonstrated a novel laser design based on synchronized emissions of light from the same type of atoms used in advanced atomic clocks. The laser could be stable enough to improve ...
Using cryo-electron microscopy, an international group of scientists has solved the atomic structure of the human aichi virus (AiV), a rather unusual but poorly characterized picornavirus that is very...
The adsorption of phosphatidylcholine (PC) vesicles (30, 50, and 100 nm nominal diameters) and of dye-labeled PC vesicles (labeled with 6% Texas Red fluorophore (TR) and encapsulated carboxy fluoresce...
