Molecular collisions at low temperatures have become known as a feature-rich quantum mechanical scattering problem. Theoretical calculations more than a decade ago have shown that a plethora of ...

Could techniques used in fundamental tests of physics 1 and in compact atomic clocks soon find broad application in navigation? Writing in Physical Review Letters 2, Tom Kornack and collaborators from ...

Chemical reactions taking place in outer space can now be more easily studied on Earth. Scientists discovered an efficient and versatile way of braking the rotation of molecular ions. The spinning ...

This news release is available in German. Chemical reactions taking place in outer space can now be more easily studied on Earth. An international team of researchers from the University of Aarhus in ...

Quark-gluon plasma is formed as a result of high energy collisions of heavy ions. After a collision, for a dozen or so yoctoseconds (that's 10-24 seconds!), this most perfect of all known fluids ...

Heating processes in the residual gas and by collisions with energetic electrons, as well as cooling owing to interaction with cold electrons, were observed in long-time storage experiments, using the ...

A big part of physics is understanding collisions and how they're not all the same. COLLISIONS! A big part of physics is understanding collisions and how they're not all the same. Mass, momentum, and ...

Astronomers detected a collision between two black holes in unprecedented detail early in 2025, offering the clearest view yet into the nature of these cosmic oddities and confirming long-held ...
