Looking for Design in Materials Design
M. E. Eberhart, D. P. Clougherty
Despite great advances in computation, materials design is still science fiction. The construction of structure-property relations on the quantum scale will turn computational empi…
Vector Polarons in a Degenerate Electron System
Dennis P. Clougherty, Charles A. Foell
We consider a one dimensional model of an electron in a doubly (or nearly) degenerate band that interacts with elastic distortions. We show that the electron equations of motion re…
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=\…
Endohedral Impurities in Carbon Nanotubes
Dennis P. Clougherty
A generalization of the Anderson model that includes pseudo-Jahn-Teller impurity coupling is proposed to describe distortions of an endohedral impurity in a carbon nanotube. Treati…
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…
