| Volume 94, Issue 4 (partial) October - December 2022  | On the Cover Ultrastrong electromagnetic fields occur not only in astrophysical settings but also in dense lepton bunches, special crystals, and at the focus of high peak power lasers. For fields of sufficient magnitude including quantum electrodynamics effects becomes essential. Electron-positron pair creation and interaction of these pairs with the fields results in fascinating phenomena. In this review these particle dynamics are analyzed and shown to exhibit complex behavior including chaotic motion with strange attractors and limit cycles, as well as cascades where the vacuum "explodes" and acts back on the strong fields. An overview of planned experiments points to new discoveries which will challenge long-held theoretical expectations.

Advertisement | The APS Science Trust Project was born out of member-demand to address misinformation about science, which has been increasing due to the broad accessibility of various streams of communication. This free virtual workshop, held on 4 consecutive Tuesdays, starting on November 29, 1:00 - 3:00 p.m. ET, via Zoom, will focus on climate change misinformation, but the skills and methods are appropriate for addressing a wide range of misinformation topics. Register now » | | | | | Advertisement | Build your on-campus physics community with help from a Women in Physics Group Grant. The APS Committee on the Status of Women in Physics (CSWP) is now accepting proposals from undergraduate and graduate students who are interested in creating new WiP groups or enhancing existing ones. The deadline for proposals is November 21. Learn more » | | | | | | Not an APS member?

Phys. 94, 045002 (2022) – Published 20 October 2022  | Additive manufacturing, called 3D printing, has become ubiquitous in classrooms, laboratories, and research centers. While printing with plastics has revolutionized prototyping and modeling, it is now possible to fabricate metal parts and devices directly from computer models by fusing metal particles together with high-intensity lasers. This review focusses on the flow of heat and material in the high temperature environment, the instabilities that arise, and the tools to control them. | | | | | | | |
