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 ...

Cycloaddition reactions represent a cornerstone of synthetic organic chemistry, facilitating the formation of cyclic structures through concerted pericyclic processes. Traditionally explained via ...

A new analysis reveals what happens when very short or narrow electron beams encounter a particle. The research is published in the New Journal of Physics. Scientists should be able to achieve a new ...

A University of Michigan study suggests that shortening laser pulses to subcycle durations can increase quantum efficiency in photoemission by up to 10 orders of magnitude without raising power or ...
