Instructions to Authors
Communications in Theoretical Physics (CTP) is published
monthly by the Institute of Theoretical Physics of the
Chinese Academy of Sciences and the Chinese Physical Society,
and online by IOP Publishing Ltd. Articles in this journal
are abstracted/indexed in Science Citation Index (SCI), Science
Citation Index Expanded (also known as SciSearch), ISI
Alerting Services, and Current Contents/Physical, Chemical
and Earth Sciences; Science Abstracts (SA), Chemical Abstracts
(CA), Mathematical Review (MR), and Russian Abstract
Journal (P), etc. Contributions from all over the
world are welcome.
The aim of Communications in Theoretical Physics is
to present important new developments in the area of theoretical
physics. Papers published in this journal are mostly
devoted to the fields of (1) Mathematical Physics and Quantum
Information, (2) Particle Physics and Quantum Field Theory,
(3) Nuclear Physics, (4) Gravitation Theory, Astrophysics
and Cosmology, (5) Atomic, Molecular, Optical (AMO) and
Plasma Physics, (6) Statistical Physics, Soft Matter and Biophysics,
(7) Condensed Matter Physics, as well as (8) Other
Areas in theoretical physics. In addition to original regular articles,
letters, research notes and rapid communications, CTP
also publishes occasionally review articles and conference proceedings.
A submission to Communications in Theoretical Physics
must be the original work of the author(s) and must not be
published elsewhere or under consideration for another publication
in a similar form. Submissions should be made through The text of the
article can be prepared using any common variant of TeX,
including Plain TeX, LaTeX, REVTeX, AMSTeX, etc. Figures
should be submitted as separate files, preferably in PS
(PostScript) or EPS (Encapsulated PostScript) formats. Data
files for drawing figures are also accepted. The text and figure
files can be packaged together into one achieve and compressed
using a common utility such as PKZip, WinRAR, WinZip,
ARJ, etc. If a submitted paper relies heavily on unpublished
material, it would be helpful to provide a copy of that material
for the use by the referee(s). If necessary, the author(s) may be
suggested to revise the manuscript. When the Editorial Office
informs/confirms the corresponding author that the article has
been accepted for publication, the author(s) will be notified to
provide an electronic version of the accepted article (including
PS or EPS files of figures if it contains), which must exactly
match the final version accepted.
Manuscript preparation
All manuscripts should be written in good English. The text
should be prepared with double line spacing and wide margins,
on numbered sheet. The structure of a manuscript should have
the following order of presentation: Article title, Author(s),
Affiliation(s), Abstract, and keywords, Main text, Acknowledgments,
Appendices (if necessary), References followed by
captions of eventual figures and tables.
Corresponding author: The name, complete postal address,
telephone and fax numbers and e-mail address of at least the
corresponding author should be given on the first page of the
Keywords: The author(s) should provide less than five keywords
that can classify and describe the content of the article.
References should be numbered with Arabic numerals consecutively
within square brackets in the text and listed at the
end of the article in the order of citation. A journal reference
should comprise author name(s), APS (American Physical
Society) abbreviated name of journal, volume number (in
boldface), year of publication, and first page, e.g.,
[1] J. Ellis, K. Enqvist, D. V. Nanopoulos, et al., Nucl. Phys.
B 276 (1986) 14.
[2] Z. T. Fu, S. K. Liu, and S. D. Liu, Phys. Lett. A 299
(2002) 507; A. Peres, Phys. Rev. Lett. 77 (1996) 1413.
A book reference should comprise author name(s), full title of
book, editor(s), publisher, place of publication, year of publication,
inclusive page number(s), e.g.,
[3] K. G. Wilson, Recent Developments in Gauge Theories, ed.
G. ’t Hooft et al., Plenum Press, New York (1980), p. 28.
Figures and Tables could be collected on separate sheets at
the end of the manuscript, if relevant, a detailed caption should
be provided for each of the figures and tables. Number figures
and tables with Arabic numerals in order of appearance in the
text. When preparing figures, the authors should pay particular
attention to the widths of lines and curves, and sizes of
some other symbols appeared in the figures, as some of them
(for example, dotted lines, dashed lines, thin lines, etc.) may
disappear after reduction if improper widths and sizes are used
when drawing the figures. Figures with width less than 7.5 cm
(half the width of the printed page) are most preferable, if not
necessary, large figures should be avoided.
The corresponding author will receive a copy of page proofs for
final reading. The corrected proofs are requested to return to
the publisher without delay. In those cases where proofs are
not returned within a reasonable period of time (more than 14
days), the publisher will read the proofs and publish the article
without author’s comments.
