Contributed abstracts for oral and poster presentations

Three types of contributed presentations

Abstracts may be submitted either for oral presentations or poster presentations:

• An oral presentation is delivered within a 13-minute timeframe: 10 minutes for presentation, two minutes for the presenter Q&A, and one minute to transition to the next speaker.
• During a poster presentation, the presenter will stand with a poster displaying their research in a designated space and engage attendees one-on-one.
• Interact sessions combine an exciting two-minute presentation with follow-up poster engagement alongside other topic-affiliated posters in a compact session.

Eligibility

To submit an abstract, you must be an APS member or a member of a reciprocal society. At the APS DFD Meeting, you may only present one talk per presenter: oral, poster, or DFD-Interact presentation. APS members may submit a contributed oral or poster abstract that lists a non-member as the presenter.

You must be logged into your APS web account to submit an abstract. If you do not have an account, you may create one.

The presenter must attend the meeting and give the presentation. The APS Program Committee, at its discretion, will accommodate author preferences regarding presentation type and schedule whenever possible.

Submitting multiple abstracts

APS can only accept one technical abstract per presenting author for the scientific program, whether it is a contributed oral, a poster, or an Interact presentation. You may present one additional abstract of a non-technical nature, on topics such as education and/or policy, at a session of broad concern to the physics community.

The APS Program Committee, at its discretion, may accept additional technical abstracts as poster presentations if space is available.

Editing abstracts

Please proofread your abstract carefully before submitting it. You will be able to edit your abstract in the submission system up until the submission deadline.

Character limits

Contributed oral and poster abstracts are limited to approximately 2,000 characters.

Formatting

Please do not attempt to override the system defaults by introducing your own formatting in your abstract. APS will only correct misspellings in the authors' names or affiliations. APS will not add additional authors or re-order the author list after the abstract submission deadline has passed.

Withdrawing a contributed abstract

You may withdraw your contributed abstract online before the abstract submission deadline. After the deadline, please contact the APS Abstract Help team to have your abstract withdrawn.

Accepted abstracts

All abstracts following the APS submission guidelines will be accepted into the program. You will receive an email in early September 2025 from APS notifying you that your abstract has been placed in the program. You are then responsible for confirming the session date, time, and requesting any necessary changes. You may contact the APS Abstract Help team.

All presenters are required to register to attend the APS DFD Meeting 2025.

Invited speaker abstract submissions

APS members may be invited to present one scientific abstract at the APS DFD Meeting 2025. Individual speakers will not be invited to speak at two consecutive APS DFD Meetings, e.g., an invited speaker who presented at DFD Meeting 2024 will not be invited to speak at the APS DFD Meeting 2025.

Exceptions are made for speakers who will receive APS Prizes and Awards at the meeting.

In addition to their invited talk, invited speakers may submit one contributed oral abstract or poster for the regular scientific program. APS will send out invited speaker letters with information about submitting abstracts and/or posters, as well as about registration.

Invited speakers must still register for the APS DFD Meeting 2025. All invited speakers will receive the Early Bird Registration rate, no matter when they register.

Invited abstract guidelines

Eligibility

An invited abstract may only have the invitee as the author. APS suggests that the invitee credit collaborating researchers in a footnote within the paper. The invitee must deliver the paper, unless a replacement speaker is agreed upon beforehand, to APS Abstract Help.

Character limit

The limit for invited abstract text is approximately 2,000 characters.

Submitting multiple invited abstracts

If you are submitting an invited abstract, you may also submit one contributed oral abstract or poster for the regular scientific program.

Withdrawing an invited abstract

If you accept an invitation to present but are later unable to do so, please contact APS Abstract Help.

Presentation time

At the APS DFD Meeting 2025, an invited paper is expected to have 25 minutes for presentation time, plus 10 minutes for questions.
