no more than two electrons may exist in a given atomic orbital; therefore an electron may only leap to another orbital if there is a vacancy there. Knowledge of the electron configuration of ...

Ionization in strong infrared fields is often viewed as electron tunnelling through a potential barrier, created by the combination of the atomic potential that binds the electron and the electric ...

Correcting this "spherical aberration" is costly and complex, meaning that only a select few scientists and companies possess electron microscopes with atomic resolution. Researchers from Tohoku ...

However, even the world's highest performance atomic resolution electron microscope is still 20 times worse than the theoretical performance, and the technology is still growing year by year. On the ...

In the first of the two Science papers, Bernevig, Song and Elcoro provide a theoretical explanation for a new bulk-boundary correspondence to explain fragile topology. The collaborators show that the ...
