Ferroelectric Phase Transitions in a Lattice Pseudo-Jahn-Teller Model

Dennis P. Clougherty

A lattice generalization of the $(b_{1 u} \oplus b_{2 g}) \otimes b_{3 u}$ 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 $s \sim k$ with $k \to 0$ where $k=\…

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 $E$ colliding with a target which is a 1D harmonic ``solid slab'' with $N$ atoms in its ground state; the…
