New Journal of Physics The open-access journal for physics www.njp.org Highlights of 2011 Advancing physics research globally NJP is evolving We won’t just publish your work; we will help you share your research with others in new and innovative ways. By featuring the people WIth a NJP vIdeO abstract yOu caN: behind the science, video abstracts have •showcase your research the potential to convey •engage with your community inspiration and •raise your visibility enthusiasm, and thereby the significance •make an impact of scientific results, beyond the concise text By including a video abstract you can enhance the visibility of your of articles. article by more than five times. In 2011, NJP articles with video abstracts were downloaded (on average) more than1400 times each.

New Journal of Physics: Highlights of 2011 New Journal of Physics – extending the global reach of physics research ImPact Factor 1,500,000 At a time when more and more journals are introducing open-access options in response to increasing demand from researchers, librarians, funding bodies and the general 1,000,0003.849* * As listed in ISI®’s 2010 Science public, New Journal of Physics (NJP) is proud to have the highest Impact Factor of all Citation Index Journal citation reports 500,000 ‘gold’ open-access journals in physics. 0 Providing a showcase for just some of our article highlights of the last 12 months, the 2007 2008 2009 2010 2011 citation performance abstracts collected here have been selected by our editorial team as a reflection of the 4.5 Impact Factor 1.4 quality, and the subject and geographical diversity of NJP’s broad coverage in 2011. Immediacy Index 4.0 1.2 Immediacy Index 3.5 1.0 3.0 NJP’s priority remains to provide permanently free access to research of the highest 2.5 0.8 quality, in the latest and most cutting-edge areas of physics. In addition to optimizing the 2.0 0.6 Impact Factor 1.5 reach and dissemination of research, we also recognize the vital role that NJP should play 0.4 1.0 0.5 0.2 in raising the visibility and profile of our authors themselves. 0 0 2006 2007 2008 2009 2010 As such, in 2011 we introduced video abstracts – a unique new integrated content stream that gives all authors the opportunity to go beyond the constraints of the written article to personally present the importance of their work to the journal’s global audience. cover image: ‘Green rings’ from Several of the highlights featured in this collection feature author videos (look out for the stock library. QR codes), which to date have been watched more than 25 000 times worldwide. Already an early success, we look forward to seeing more of our authors take advantage of this new service in 2012. North America Korea China Spain Germany Rest of Europe UK Rest of Asia A second major development aimed at improving our overall user experience has been Japan Central/South America France Australasia India Middle East the introduction of a new and enhanced format for articles. Implemented as part of the Italy Africa ongoing IOPscience ‘Article Evolution’ project, we are committed to optimizing our online delivery in response to the feedback we receive from you, our authors and readers. In addition to new and improved online services, in 2012 you can also look forward to NJP continuing to publish in the very latest areas of physics through a new series of invited focus issue collections that will include ‘Quantum Spin Liquids’, ‘Graphene Optics’, ‘Optomechanics’, ‘Physics for Biology at a Mesoscopic Scale’ and ‘Quantum Tomography’ (to name just a few). NJP’s success is due entirely to the fantastic support of the physics community worldwide. On behalf of the journal I would like to thank all of our Board members, authors, referees, partners and readers for their vital contribution to the journal’s ongoing development. And finally, thank you for your support. I hope you will find this collection of interest and that you will consider NJP as the journal of choice for your next paper.
