It was a bold thought experiment: that only one electron makes up the entire universe. The most famous conversation about it took place between Richard Feynman, PhD, and John Wheeler, PhD, both ...

A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions. The movement of electrons in a lattice ...
