Evidence for moving breathers in a layered crystal insulator at 300K
FM Russell and JC Eilbeck
Abstract
We report the ejection of atoms at a crystal surface caused by
energetic breathers which have travelled more than $10^7$ unit cells
in atomic chain directions. The breathers were created by
bombardment of a crystal face with heavy ions. This effect was
observed at 300K in the layered crystal muscovite, which has linear
chains of atoms for which the surrounding lattice has $C_2$
symmetry. The experimental techniques described could be used to
study breathers in other materials and configurations.
