You can "hack" the address, at least, as follows. After typing the
author name, use Ctrl+Enter or Insert > Formatting > Ragged Line Break
to create a second author line. Type the address there and, if you wish,
select it and use the font formatting option to change its size. That
should keep the address with the author in two column format.
You could probably do something similar for the abstract, but by this
point you are likely better off with a different document class.
