Super Long-Lived Neutral Excitations of the 1/3 Laughlin Liquid
摘要
The long-term relaxation dynamics of neutral excitations with spin 1 in the Laughlin liquid at an electron filling factor of 1/3 has been studied. It has been found that there are two types of excitations with the same energies, the relaxation times of which to the ground state differ by at least two orders of magnitude. Assumptions are made about the nature of these excitations.
