AIP Style

References should be set as a double-spaced list at the end of the text. The names, including initials, of all authors in each reference should be given (in the text, the use of “et al.” is permissible).

All references to books and journal articles, listed at the end of the paper, are to appear in only one of these three formats:

  1. By number, in order of first appearance, presenting the names of the authors, the journal name, volume, first page number only, and year. This paper will be listed as the 19th in the list of references and cited as 19 or Ref. 19:

    19L. M. Pecora, T. L. Carroll, G. A. Johnson, D.J. Mar, and J. F. Heagy, Chaos 7, 520 (1997).
     
  2. In alphabetical order according to the first author’s last name, including, in addition to the name, the title of the paper cited, journal name, volume, first and last page, and year. This paper will be cited as “Pecora et al. (1997).” 

    Pecora, L. M., Carroll, T. L., Johnson, G. A., Mar, D. J., and Heagy, J. F., “Fundamentals of synchronization in chaotic systems, concepts, and applications,” Chaos 7, 520–543 (1997).
     
  3. Alphabetically listed references (with full titles and page ranges) may be numbered according to their alphabetical order and cited by their number.

In-text Citation - General Rules

  • Cite references in numerical order
  • Numerals are to be placed after punctuation
  • Refer to authors in text by Surname / Family only
  • Use all authors names for a maximum of three authors. Where there are four or more authors use the first authors name and the expression "et al." ('et al'  is a Latin phrase meaning 'and others' ) eg. Smith et al.
  • Place citation numbers where they will not be confused for a different meaning:

                     A recent measurement2 of rv

                           not

                     A recent measurement of rv 2
