At this time, there are no AIP journal-specific style files. Please use one of the Physical Review style files that most closely resembles the style you are trying to achieve. Do not use any private style files, or ``ersatz'' AIP style files found at various FTP sites. AIP does not support these files.
The easiest thing to do is to use the following documentstyle line.
\documentstyle[preprint,aps,prb]{revtex}
This documenstyle line will be sufficient for most journals printed by AIP. Using this documentstyle line will give you a preprint (12 point, one column) manuscript, with superscripted reference citation numbers. (If you wish to number your equation numbers by section, use the eqsecnum style; use amssymb, amsfonts for symbols and fonts, etc.)
