International Conference on Photonic, Electronic and Atomic Collisions is a biennial scientific conference that brings together researchers in atomic physics, molecular physics, optics, and surface science to discuss advances in collisions involving photons, electrons, ions, and atoms. The meeting functions as a nexus connecting work from laboratories and universities such as Max Planck Society, Lawrence Berkeley National Laboratory, Massachusetts Institute of Technology, Harvard University, and University of Cambridge. Attendees often include members from institutions like National Institute of Standards and Technology, CERN, Imperial College London, and École Polytechnique.
The series began in 1958 following initiatives by researchers associated with Royal Society, American Physical Society, and the International Union of Pure and Applied Physics to coordinate post‑war research in collision phenomena. Early meetings featured contributions from scientists linked to Enrico Fermi, Niels Bohr, I. I. Rabi, Lise Meitner, and laboratories including Rutherford Appleton Laboratory and Brookhaven National Laboratory. Over decades the conference adapted to developments driven by milestones such as the invention of the laser, the establishment of synchrotron radiation facilities, and the construction of the Large Hadron Collider. The Cold War era exchanges involved delegates from Los Alamos National Laboratory, Kurchatov Institute, Joint Institute for Nuclear Research, and Institute of Atomic Energy (Dubna), while later meetings emphasized international collaboration with participation from National Institutes of Health and European Molecular Biology Laboratory researchers.
The scope spans experimental and theoretical studies of collisions involving participants associated with photon science facilities like SLAC National Accelerator Laboratory and DESY, as well as electron and ion beam work at Oak Ridge National Laboratory and TRIUMF. Typical topics include investigations connected to laser spectroscopy, quantum electrodynamics, electron scattering, ion-atom collisions, and photoionization. Sessions often reference methods developed at Stanford University, California Institute of Technology, Tokyo University, and University of Oxford and applications in fields represented by NASA, European Space Agency, Siemens, and IBM Research. Intersections with research directions of François Englert, Steven Chu, Claude Cohen-Tannoudji, and groups at University of California, Berkeley are common.
An international advisory committee oversees selection, modeled on governance practices of bodies like International Council for Science and European Physical Society. Local organizing committees have been hosted by universities including University of Tokyo, University of Melbourne, University of Toronto, University of Colorado Boulder, and University of Munich. The conference routinely solicits input from societies such as Optical Society of America, American Chemical Society, Royal Society of Chemistry, and Institute of Physics. Sponsorship and funding channels have involved organizations like National Science Foundation, European Research Council, Japan Society for the Promotion of Science, and Deutsche Forschungsgemeinschaft.
Meetings travel globally with past sites in cities tied to major research centers: Paris, London, Berlin, Prague, Moscow, Warsaw, Tokyo, Sydney, Melbourne, Vancouver, Toronto, Berkeley, California, Stockholm, Rome, Lisbon, Istanbul, Athens, and Seoul. Notable editions were held near facilities at European XFEL, ISIS Neutron and Muon Source, Advanced Photon Source, and SPring-8. Special satellite symposia have been organized in conjunction with events like International Congress of Quantum Chemistry and Gordon Research Conferences.
Proceedings have been published in series affiliated with publishers and organizations such as Springer Science+Business Media, Elsevier, Institute of Physics, and journals including Physical Review A, Journal of Physics B, Nature Communications, and Chemical Physics Letters. Selected papers are often presented at workshops linked to Royal Astronomical Society and archived in repositories associated with arXiv and institutional libraries at Princeton University, Columbia University, and Yale University.
The conference has hosted Nobel Laureates and eminent researchers connected to Nobel Prize in Physics, including individuals affiliated with Stanford Linear Accelerator Center, Bell Labs, Fermilab, and Max Planck Institute for Quantum Optics. Contributions have advanced topics pioneered by figures such as Paul Dirac, Wolfgang Pauli, Erwin Schrödinger, Richard Feynman, Julian Schwinger, and later innovators like William D. Phillips, John L. Hall, Theodor W. Hänsch, and Arthur Ashkin. Breakthroughs discussed include developments in ultrafast spectroscopy, cold atom physics, Bose–Einstein condensation, and techniques used at LIGO and in quantum information experiments at MIT Lincoln Laboratory.
The conference has associated honors modeled on awards like the Frank Isakson Prize, Maxwell Medal, and Wolf Prize, with sessions acknowledging lifetime achievements and early-career contributions comparable to fellowships from Royal Society, National Academy of Sciences, American Academy of Arts and Sciences, and awards by European Physical Society. Recipients often hold positions at institutions such as University of Chicago, Cornell University, Yale University, ETH Zurich, and Peking University.
