In this Focus point issue we look at the frontiers of beam dynamics in particle accelerators. These machines are unique scientific tools that provide focused high-density beams of sub-atomic particles such as electrons, protons or ions, at energies unparalleled in any other areas of laboratory-based science. They have been applied to vast range of problems in the last century or so, with circular colliders playing a special role in discovering new particles and new physics, with energy and particle collision rates of several orders of magnitude higher than those of pioneer colliders in the early 1960s. This Focus Point issue covers the field of particle beam physics, with a loose classification into the categories of advances in the field, challenges, and broader applications. This includes exciting topics such as non-linear beam dynamics, the Large Hadron Collider, the SuperKEKB, and the Future Circular Collider, the physics that occurs when two beams collide and some papers on the future advances of the field. We hope this issue is both exciting and inspiring for our community, and of interest beyond our community as well.
