VSEPR theory provides a practical way to predict the 3D shapes of molecules by focusing on how electron pairs repel each other. This model explains why atoms arrange in specific geometries, from ...

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 ...

For years, one tiny mismatch in particle physics carried outsized hopes. The muon, a heavier and short-lived cousin of the ...

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 ...

Plasma forms in gaps ten times smaller than classical theory predicts possible, driven by electron cascades on the substrate ...

A newly measured value of an electron’s magnetic moment 1 — a property of its spin and charge — is twice as precise as the one physicists have used for the past 14 years. The electron magnetic moment ...

Résumé of the many-electron problem -- The occupation number representation (second quantization) -- The Hartree-Fock method and the free-electron gas -- Plasma oscillations in a free-electron gas -- ...
