Physicists bring human-scale object to near standstill, reaching a quantum state（图）
量子态 引力 原子尺度
2023/6/19
To the human eye, most stationary objects appear to be just that — still, and completely at rest. Yet if we were handed a quantum lens, allowing us to see objects at the scale of individual atoms, wha...
Coming soon to a lab tabletop near you: a method of magneto-thermal imaging that offers nanoscale and picosecond resolution previously available only in synchrotron facilities.
Zoom into an online particle physics conference, and the chances are you’ll hear the term muon anomaly. This is a longstanding tension with the Standard Model of particle physics, seen in the magnetis...
Cornell researchers have discovered a rare “pseudogap” phenomenon that helps explain how the superconducting transition temperature can be greatly boosted in a single monolayer of iron selenide, and h...
Researchers from Cornell’s School of Applied and Engineering Physics and Samsung’s Advanced Institute of Technology have created a first-of-its-kind metalens – a metamaterial lens – that can be focuse...
The LHCb collaboration has measured a difference in mass between two particles of 0.00000000000000000000000000000000000001 grams – or, in scientific notation, 10-38 g. The result, reported in a paper ...
These now-iconic detectors are critical to a new era of exploration for the ATLAS experiment. In the coming years, a major upgrade to the LHC – known as the High-Luminosity LHC – aims to crank up the ...

In 2018, Cornell researchers built a high-powered detector that, in combination with an algorithm-driven process called ptychography, set a world record by tripling the resolution of a state-of-the-ar...
An interdisciplinary team of Cornell researchers has taken its breakthrough discovery – which melded the ability of soft organic materials to spontaneously self-organize with quantum materials to crea...
Aheart surgeon doesn’t need to grasp quantum mechanics to perform successful operations. Even chemists don’t always need to know these fundamental principles to study chemical reactions. But the worki...
Cornell engineers used precisely timed laser pulses to control changeable properties in a quantum material, pioneering a method that may have wide applications across a class of materials with immense...
