Acta Physica Polonica was established by the Polish Physical Society in 1920. In 1970 it was split into Acta Physica Polonica A (published by the Institute of Physics of the Polish Academy of Sciences), whose scope includes general physics, atomic and molecular physics, condensed matter physics, optics and quantum optics, biophysics, quantum information, and applied physics, and Acta Physica Polonica B (published by the Jagiellonian University), which covers mathematical physics, particle and nuclear physics, relativity, astrophysics, and statistical physics. The editors-in-chief are Jan Mostowski and Michał Praszałowicz. In 2008, Acta Physica Polonica B Proceedings Supplement was established.
