the quantum-mechanical hydrogen atom is stable. If the hydrogen atom obeyed the laws of classical mechanics, by contrast, the electron would spiral into the proton in a tiny fraction of a second ...

The new work involves a more intricate kind of measurement performed on a single atom to demonstrate clearly ... that a nuclear spin is actually a quantum mechanical object by simply watching ...

Did these researchers truly just crack our fundamental concepts of (quantum) physics wide open ... in the photonic energy getting absorbed by an atom, boosting the energy state of its electron ...

Instead, neutrons are held together inside an atom's nucleus solely by something ... Li calls it "a pretty crazy solution to a quantum mechanical problem." The team calls the newly discovered ...

Now, engineers have discovered that quantum materials just a single atom thick can do the job - using only light. (Nanowerk News) For decades, scientists have relied on electrodes and dyes to track ...
