Reviews of Modern Physics Reviews of Modern Physics Reviews of Modern Physics is a quarterly peer-reviewed scientific journal published by the American Physical Society. It was established in 1929 and the current editor-in-chief is Michael Thoennessen. The journal publishes review articles, usually by established researchers, on all aspects of physics and related fields. The reviews are usually accessible to non-specialists and serve as introductory material to graduate students, which survey recent work, discuss key problems to be solved and provide perspectives toward the end. RMP is arguably one of the most, if not the most, prestigious, authoritative and highly impacting journals in the field
