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 pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

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 ...

Electron beams (cyan haze in top left) are routinely used to determine the molecular structures of biomolecules in cryo-electron microscopy ...
