One particle on two paths: Quantum physics is right

 Quantum Physics News
 11 May 2022
The double-slit experiment is the most famous and probably the most important experiment in quantum physics: individual particles are shot at a wall with two openings, behind which a detector measures where the particles arrive. This shows that the particles do not move along a very specific path,...

Discovering new properties of magnetism that could change our computers

 Quantum Physics News
 11 May 2022
Modern computers use electrons to process information, but this design is starting to reach theoretical limits. However, it could be possible to use magnetism instead and thereby keep up the development of both cheaper and more powerful computers, thanks to work by scientists from the Niels Bohr...

A zero-cost way to improve neutron scattering resolution by 500%

 Quantum Physics News
 09 May 2022
Scientists pushing the limits of the world's most advanced neutron scattering instruments know that a small amount of distortion in their measurements is inevitable. For some experiments, this distortion is easily accounted for, but in other types of research it can cause inaccurate findings....

A new window into the world of attosecond phenomena

 Quantum Physics News
 09 May 2022
They are everywhere, around us and within us. Phenomena lasting trillionths of a second form the core of chemistry and biology. It is only recently that we have begun to try to accurately record their actual course, with moderate success. However, physicists from Cracow have proven that the new...

The standard model of particle physics may be broken, expert says

 Quantum Physics News
 09 May 2022
As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is "When are you going to find something?" Resisting the temptation to sarcastically reply "Aside from the Higgs boson, which won the Nobel Prize, and a whole slew of new composite...

Collisions with electrons cool molecular ions

 Quantum Physics News
 09 May 2022
A lone molecule free in cold space will cool by slowing down its rotation—it will spontaneously lose its rotational energy in quantum transitions, typically only once in many seconds. This process can be accelerated, slowed down, or even inverted by collisions with surrounding particles....
