Charge coupling to anharmonic lattice excitations in a layered crystal at 800K

Abstract

A study of charged particle and quasi-particle anharmonic lattice excitations in a meta-stable crystal of layered structure at high temperature has shown that a mobile lattice excitation called a quodon can bind securely to a hole or electron. Quodons are decoupled from phonons and can propagate along atomic chains of more than $10^8$ atoms at 800K. Their relevance to high Tc superconductors is discussed.
