Scientific Program

The scientific program of ICPEAC 2023 will consist of five plenary lectures of 60 minutes length each (including discussion), more than 60 invited progress reports (30 minutes, including discussion), a smaller number of special reports selected from the contributed abstracts (15 minutes, including discussion), and several hundred posters. Plenary talks are of general interest to all participants. Progress reports and special reports will be arranged in two parallel sessions and are intended to provide an in-depth view of the current state of research across the different topics of the ICPEAC community. In addition, the winner of the IUPAP Early Career Scientist Prize (previously Young Scientist Prize) in Atomic, Molecular and Optical Physics will be invited to present a 30-minute talk (including discussion).

An evening lecture will be delivered by Canada’s most recent Nobel Laureate in Physics, Professor Donna Strickland from the University of Waterloo, on Wednesday, July 26. The lecture is open to conference participants, accompanying persons, and the general public free of charge.

Continuing a relatively recent ICPEAC tradition that was started in 2013, a set of four tutorial lectures will take place on July 25 at the University of Ottawa (exact location to be determined).  The lectures will provide pedagogical accounts of the most recent advances in the field of photonic, electronic and atomic collisions. While targeting students and young postdocs, all registered ICPEAC delegates are welcome to attend the tutorials free of extra charge.


Final Conference Program

A detailed program and schedule will be available here in June 2023. The final program, including the abstracts of the tutorial, plenary, and progress report talks will be published in the printed ICPEAC 2023 Conference Handbook together with the synopses of the special reports and a list of accepted posters. The Handbook will be distributed to ICPEAC delegates at the registration desk. In addition, all accepted abstracts will be available online in a book of abstracts.



The following topics will be covered in the ICPEAC program:

Photon impact – weak fields (synchrotron, FEL)
Photon impact – strong fields (femto/atto physics)
Electron collisions with atoms, molecules and ions
Collisions between ions, atoms and molecules
Anti-matter & other exotic particle collisions
Field-assisted collisions
Ultracold atomic and molecular physics
Collisions with surfaces and condensed matter
Experimental techniques
…and related topics


ICPEAC Business Meeting

All ICPEAC attendees are invited to participate in the ICPEAC business meeting on Tuesday, August 1 at 12:30 pm. The meeting will include the ICPEAC treasurer’s and secretary’s reports, the announcement of new ICPEAC committee members, a presentation on ICPEAC 2025 in Sapporo, and general information on other future ICPEAC meetings.


Executive and General Committee Meeting

The ICPEAC Executive Committee will convene in the early evening of Tuesday, July 25 in Meeting Room 210 in the Shaw Centre. The ICPEAC Executive and General Committees will meet on Thursday, July 27 from 12:30 to 14:00 in the same room (lunch will be served). The current members of the Executive and General Committees are listed at the end of this announcement, and the new members will also be invited to the lunch meeting on Thursday.
