Modern Physics Letters A《现代物理快报A》(一年40期). This letters journal, launched in 1986, consists of research papers covering current research developments in Gravitation, Cosmology, Astrophysics, Nuclear Physics, Particles and Fields, Accelerator physics, and Quantum Information. A brief review section has also been initiated with the purpose of publishing short reports on the latest significant experimental findings and important new theoretical developments. Critical summaries and comments on a topic of current interest can also be considered as brief reviews, which preferably aim at non-experts. These reviews should examine the present state of the subject and attempt to provide future research in perspective.
