One specificity of physics in the Balkans is the existence of a tradition, more than 30 years long, of organizing triennial Balkan congresses (International General Physics Conferences) within the Balkan Union of Physicists (BPU) as a platform for the presentation of the research results of hundreds of participants and their collaborators with the Balkans, from Europe and the world.

The aim of this Focus point of EPJ Plus is to contribute to an overview of the state of the art of research in physics in the Balkans. Eleven of the seventeen plenary and invited lecturers at the BPU11 Congress contributed to this issue. The Focus Point provides valuable insights and highlights results in already established areas, as well as some interesting new research avenues to pursue. This issue contains mainly original scientific papers with review elements in the fields of Solid State Physics, Physics of Materials, Econophysics, Quantum Optics and Laser Physics, Open Quantum Systems, Cosmic Rays and Hubble Tension in Cosmology, Nuclear and Collider Physics.

All articles are freely accessible until 31 May 2024. For further information, read the Editorial.
