The study of simple metal clusters has burgeoned in the last decade, motivated by the
growing interest in the evolution of physical properties from the atom to the bulk solid, a …

Abstract In the Born-Oppenheimer approximation for molecular dynamics as generalized by
Born and Huang, nuclei move on multiple potential-energy surfaces corresponding to …

It is widely recognized nowadays that conical intersections of molecular potential-energy
surfaces play a key mechanistic role in the spectroscopy of polyatomic molecules …

Aimed at graduate physics and chemistry students, this is the first comprehensive
monograph covering the concept of the geometric phase in quantum physics from its …

The first half of the title of this book may delude the uninitiated reader. The term'" Jahn-Teller
effect," taken literally, refers to a special effect inherent in particular molecular systems …

During the last few years, considerable interest has been focused on the phase that waves
accumulate when the equations governing the waves vary slowly. The recent flurry of activity …

The pseudo-Jahn− Teller effect is the only source of instability and distortions of high-
symmetry configurations of polyatomic systems in nondegenerate states, and it contributes …

The fundamental theory of the geometric phase is summarized in a way suitable for use in
molecular systems treated by the Born-Oppenheimer approach. Both Abelian and non …

According to standard quantum mechanics, the motion of a charged particle can sometimes
be influenced by electromagnetic fields in regions from which the particle is rigorously …

It is shown that in crystals the semiclassical quantization condition for energy levels of
electrons in the magnetic field depends on Berry's phase. When the electron orbit links to the …
