The basic hydrogen atom is the simplest of all atoms ... which Bohr characterized with different values of a first, ‘principal’ quantum number 2. This bold hypothesis could explain some ...

Every so often, in the vast reaches of space, a hydrogen atom's electron can flip its spin ... understand spin, dabble in quantum mechanics, and figure out this whole 21 cm radiation thing.

UCLA physicists have developed a new thin film that uses far less of the rare thorium-229 while also being significantly less ...

New atomic clocks are more accurate than those used to define the second, suggesting the definition might need to change ...

These molecular structures typically have a central metal atom surrounded ... Dutta told Quantum. The paper notes that it is critical to bring down the cost of green hydrogen — hydrogen ...

At ultracold temperatures, interatomic collisions are relatively simple, and their outcome can be controlled using a magnetic ...

For decades, scientists have relied on electrodes and dyes to track the electrical activity of living cells. Now, engineers have discovered that quantum materials just a single atom thick can do the ...

Now, engineers have discovered that quantum materials just a single atom thick can do the job with high speed and resolution -- using only light. For decades, scientists have relied on electrodes ...
