Invited Abstract Guidelines

Invited Speaker Talks

APS members may be invited to present one scientific abstract per APS March or April meeting. Individual speakers will not be invited to speak at two consecutive March or April meetings, e.g. an invited speaker who presented at March Meeting 2019 will not be invited to speak at March Meeting 2020.

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

Invited speakers may submit one contributed abstract for the regular scientific program in addition to their invited talk. APS membership is not required, but you will need to create an APS web account in order to submit an abstract.

Please note that invited speakers must still register for the meeting. Your confirmation email will specify whether you need to pay for your own meeting registration, or if you are sponsored by a unit.

Plenary Speaker Talks
APS April Meeting plenary speakers may only give a plenary talk once every three years, e.g., a 2017 plenary speaker may not give another plenary talk until 2020.

Invited Abstract Guidelines

An Invited Abstract may have only one author, the invitee. It is suggested that you credit your collaborating researchers in a footnote within your paper. Please note that the limit for invited abstract text is approximately 2,000 characters. The invitee must deliver the paper (unless a replacement speaker is agreed upon beforehand) to APS Abstract Help (

Submitting Multiple Invited Abstracts
One additional abstract of a non-technical nature may be presented at a session of broad concern to the physics community if it is sponsored by an APS Forum or Committee.

Withdrawing an Invited Abstract
If an invited speaker accepts an invitation to present but is later unable to do so, the speaker must contact APS Abstract Help (

Presentation Time
At the APS March and April meetings, an invited paper is usually given 30 minutes for presentation plus six more minutes for questions. Unit meeting presentation times vary.
