Quantum effects can play an important role in chemical reactions. Physicists have now observed a quantum mechanical tunneling reaction in experiments. The observation can also be described exactly in ...

A team of researchers led by the University of Innsbruck have observed a quantum tunneling effect in experiments that build off 15 years of research into such reactions and marks the slowest charged ...

“Through this study, we were able to find clues about how electrons behave when they pass through the atomic wall,” stated Professor Dong Eon Kim. Physicists have been mystified for more than a ...

The electronic chip and the Van der Waals complex with an internuclear distance 0.39 nm. In combination with the improved Coulomb-corrected strong-field approximation (ICCSFA) method developed by the ...

Porphyrins are organic molecules that appear in the central region of macromolecules such as chlorophyll and hemoglobin, and have a metal atom at their center that determines their specific function.

Quantum effects are the surprising and often counterintuitive phenomena that occur at the nanoscale, where the laws of classical physics break down and the principles of quantum mechanics dominate.

Tunneling reactions in chemistry are very difficult to predict. The quantum mechanically exact description of chemical reactions with more than three particles is difficult, with more than four ...

(Nanowerk News) Tunnelling is one of most fundamental processes in quantum mechanics, where the wave packet could traverse a classically insurmountable energy barrier with a certain probability.
