Science Citation Styles
In the sciences, there are fewer standard styles. Often different publishers will have different styles and there may not be one standard for each discipline.
Some citation styles require you to use the journal abbreviation instead of the full title. Use these websites to help you find the abbreviations.

Physics does not have a current standard style. You can use the AIP Style Manual, 4th edition, but it is not current. To double check, you might want to check with an individual journal.
