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

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

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

Scientists pushed photons across the universe to test the speed of light—and found Einstein’s cosmic speed limit still holds ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

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 ...

The study of Quantum Boltzmann Equations and Bose–Einstein condensation forms a vital nexus in modern theoretical physics, bridging quantum statistical mechanics and kinetic theory. The Quantum ...

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 ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

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 ...
