American Institute of Physics (AIP)

From 1 January 2025 to around 10 December 2025, you can publish Open Access free of charge in the two AIP journals: 'Journal of Applied Physics' and 'Physics of Plasmas'. This applies to articles included in the 2025 volume of the journals.

AIP has announced that these two journals are now Open Access as part of the Subscribe to Open (S2O) publishing pilot. Thus, content published in the 2025 volume of the journals is available as Open Access, and authors can publish Open Access in these journals for free in the 2025 volume.

The deadline for accepting articles for the current year's volume is usually around 10 December. If the article is not included till 2026, the author will not know whether an APC is charged or whether the article is published Open Access for free till 1 March 2026. In practice, AIP handles this by withholding any APC charges until it is clarified whether an APC needs to be paid or not.

Therefore, it is important that the article is accepted before 10 December 2025, if you want to publish it for free as Open Access.

• the author does not have to pay an article processing charge (APC)
• the article is published with a CC-BY license *
• the author retains copyright *
• the article (Published version) becomes immediately available as Open Access
• the article (Published version) can be archived in DTU Orbit without an embargo period

AIP’s Subscribe to Open (S2O) program

The Subscribe to Open (S2O) relies on institutional journal subscription renewals, and thereby supports the journals. Since our participation threshold from renewing subscribers was met, all articles published in the journals this year are now fully Open Access. Articles are then published under a Creative Commons license (CC-BY). If the goal is not met, access to the journal's content remains paid, and authors are charged APC to publish in the journal as usual.
