18. The low-frequency optical conductivity may be approximated by the expression (Formula presented) and (Formula presented) We attribute the small value of (Formula presented) to the overdamping in the system, with (Formula presented) rather than to a large effective mass (Formula presented) as reported in Ref. 13.
