Ferroelectric Phase Transitions in a Lattice Pseudo-Jahn-Teller Model
Dennis P. Clougherty
A lattice generalization of the pseudo-Jahn-Teller model is analyzed within mean-field theory. Ferroelectric or antiferroelectric ground state…
Anomalous Threshold Laws in Quantum Sticking
Dennis P. Clougherty
It has been stated that for a short-ranged surface interaction, the probability of a low-energy particle sticking to a surface always vanishes as with where $k=\…
Theory of Spontaneous Polarization of Endohedral Fullerenes
Dennis P. Clougherty, Frederick G. Anderson
A pseudo-Jahn-Teller model describing central atom distortions is proposed for endohedral fullerenes of the form A@C where A is either a rare gas or a metal atom. A critical…
Low Energy Behavior of Quantum Adsorption
D. P. Clougherty, W. Kohn
We present an exact solution of a 1D model: a particle of incident energy colliding with a target which is a 1D harmonic ``solid slab'' with atoms in its ground state; the…
