Communications in Theoretical Physics (CTP) is a major academic platform in China's theoretical physics community. Founded by Academician Peng Huanwu in 1982, it was indexed by SCI in 1985, becoming China's first domestically published comprehensive academic journal dedicated to theoretical physics. The journal has always been committed to free publication and open communication, and does not charge authors any page fees.

CTP covers all interdisciplinary areas of theoretical physics, including quantum information, high-energy physics, gravitation and cosmology, condensed matter theory, statistical physics, biophysics, atomic and molecular physics, mathematical physics, and many other frontier fields. The journal adheres to the principle of "run by scientists". Academician Sun Changpu serves as the Editor-in-Chief, supported by a high-level editorial board. CTP follows a rigorous review process that emphasizes academic quality and supports authors' professional growth.

Once published, articles are promoted through multiple channels. The journal offers special features such as Editor's Suggestion and Chinese Highlights, and regularly organizes events like Meet the Editor-in-Chief, actively helping young researchers grow and disseminate their work.

With a 2026 JCR quartile of Q1, CTP is becoming a key window for showcasing the level of theoretical physics research in China and for promoting international exchange. Recently, a special section "Theoretical Physics for AI" has been launched, and researchers worldwide are warmly invited to follow and submit to the journal.

CTP follows a rigorous and efficient peer-review process, emphasizing academic quality and a positive author experience. All manuscripts are submitted through the online system, and the entire process is free of charge — no page fees or review charges apply.
