In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

The Einstein–de Haas effect, which links the spin of electrons to macroscopic rotation, has now been demonstrated in a ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

Quantum mechanics is very impressive. But an inner voice tells me that it is not yet the real thing. The theory produces a good deal but hardly brings us closer to the secret of the Old One. I am at ...

We know that Einstein’s general relativity is, strictly speaking, wrong. That’s because it doesn’t account for quantum effects despite the fact that those e ...

The study of quantum gases and Bose-Einstein condensates (BECs) continues to redefine our understanding of matter at ultracold temperatures. When cooled to nanokelvin regimes, quantum gases exhibit ...

The Einstein-de Haas effect has been observed in a quantum fluid, showing that changes in magnetization transfer angular ...

A hundred times more than relativity theory -- "An act of desperation" -- The impudent Swabian -- The gypsy life -- Two pillars of wisdom -- The perfect instruments of the creator -- More heat than ...

On 9 July 1925, Heisenberg sent a paper titled ‘Quantum-theoretical re-interpretation of kinematic and mechanical relations’ to Max Born, whom he was assisting at that time, and Born sent the paper to ...

A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it's the backbone of technologies that shape our lives, from lasers and microchips to quantum ...
