Physical Review Letters (PRL) is the world’s premier physics letter journal and the American Physical Society’s flagship publication. Since 1958 it has contributed to APS’s mission to advance and diffuse the knowledge of physics by publishing seminal research by Nobel Prize–winning and other distinguished researchers in all fields of physics. PRL publishes short, high-quality reports of the most influential developments and transformative ideas in the full arc of fundamental, applied and interdisciplinary physics research. It is distinctive in the depth and breadth of its coverage of the broad subfields of physics. PRL welcomes manuscripts that report on pivotal advances that will influence the research of others. All published Letters meet at least one of its strict acceptance criteria.
