A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

Now, in a paper for Physical Review Research, researchers at the Stevens Institute of Technology report an important new breakthrough: a simple but powerful formula that describes the precise closed ...

Austrian physicist Erwin Schrödinger developed quantum theory’s wave equation, which describes quantum systems as waves that ...

Quantum mechanics can explain and recover classical results under some specific approximations. However, deriving quantum mechanical results strictly from classical assumption is generally not ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that would quietly foreshadow one of the deepest truths in physics. While ...

The original version of this story appeared in Quanta Magazine. In the fall of 2022, a Princeton University graduate student named Carolina Figueiredo stumbled onto a massive coincidence. She ...

Physicists at the UK’s Central Laser Facility have recorded the first observation of quantum radiation reaction, detecting how electrons lose energy in ways that classical physics cannot explain when ...

One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...
