There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...

While quantum mechanics is arguably our most successful theory of nature, it is perhaps best known for its strangeness. Quantum theory—and its key mathematical tool, the wave function—excels at ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Unification is an ancient goal in physics.

We explore Objective Collapse Theories in a down to earth objective way. Objective Collapse Theories offer a explanation of quantum mechanics that is at once brand new and based in classical mechanics ...

Physicists have proposed a way to extract the internal quantum states of electron wave packets by analyzing how those packets ...

Quantum theory explains the behavior of matter and energy at the smallest scales, like atoms and subatomic particles. Unlike ...

Every once in a while we come across a physics story that seems very interesting – but we just don’t know what to make of it. The latest comes in the form of a press release from Brown University in ...

Wave chaos explores the complex, often unpredictable behaviour of wave systems in environments where classical dynamics are chaotic. This interplay between deterministic ray trajectories and ...
