Outreach and research results featured in the news
The press is communicating some of our results (as well as their importance and significance) to the general public. This is a role that professional societies (e.g., the American Physical Society) are strongly urging scientists to fill.
Outreach efforts to the general public have been repeatedly described by policymakers as crucial for the support for science.
Work by our group has been featured in:
2013: Our preprint on "Vindicating Heisenberg" (arXiv:1308.4853) was featured in the Nov. 1, 2013, issue of Physics World. There, Philip Ball wrote that "...an interesting perspective on the error-disturbance relationships of Heisenberg and Ozawa, in a preprint by Justin Dressel and Franco Nori: arxiv:1308.4853. They too question whether Ozawa's definitions capture the spirit of Heisenberg's, and consider a different way of formulating the relationship that depends on the specifics of instrumentation - that is, on "information that pertains to a single detector event at a particular time." They also point out that the discussion bears on the notion of contextuality advanced in 1967 by Kochen and Specker, drawing on John Bell's work. In essence, Kochen and Specker proposed - and subsequent studies have proved - that the predictions of quantum mechanics are incompatible with any hidden-variables theory in which the values of the variables do not depend on the precise experimental context by which they are measured."

2012: A recent preprint Chirality and angular momentum in optical radiation writes about our work in their introduction: Originally termed the "Lipkin zilch" the optical chirality measures were found to be distinct from stress-energy and were initially dismissed as having no ready physical interpretation, but were later associated with conservation of polarization of the electromagnetic field [1, 2]. Recent work by Bliokh and Nori has uncovered close connections between the optical chirality density and such measures as polarization helicity and energy density .

ScienceDirect has nearly 11 million regular users which means that the Top25 lists provide an authoritative reflection of readership habits. These reports are generated quarterly, in order to truly reflect usage patterns. The Top25 is based on usage behaviour from the prior three months. So the Top25 lists published in September represent results of ScienceDirect usage during April, May and June of that year."

Nature Editor's summary: Casimir on the move.
Two mirrors held parallel to each other in a vacuum experience an attractive force, known as the Casimir effect, which combines aspects of quantum vacuum behaviour with relativity. The force arises when vacuum fluctuations - virtual particles flitting in and out of existence - reduce the radiation pressure between the plates and generate an inward force. The static effect has been well studied, but theory also predicts a dynamical Casimir effect arising from a mismatch of vacuum modes in time rather than space. This paper presents the first observation of this phenomenon in a superconducting circuit.

2010: Our prediction on the production of electron vortex beams (PRL 2007) has been implemented experimentally by three groups, published in two papers in Nature in 2010 and one in Science in 2011.
These results (our theory PRL and the subsequent two experiments in Nature) have been featured in Nature Nanotechnology: ( "Electron microscopy: A new spin on electron beams" (local PDF).
The first experiment is described here: Electrons spiral to a new future
and they wrote this in their Nature paper:
"Recently, it has been shown  that electron wave packets can carry a well-defined OAM, using the semi-classical paraxial solutions of the Schrödinger equation with phase singularities. The present experiment confirms the prediction  of quantum electron waves carrying OAM."
Ref. 13 is our 2007 PRL (the one listed above). (local PDF) .
Afterwards, a group in Antwerp did an improved experiment [Nature (2010)].
Physics World interviewed us on this topic: Holography puts electrons in a twist.
2011 experiments appeared in Science: Electron Vortex Beams with High Quanta of Orbital Angular Momentum. A Perspective on this is here: A New Twist for Electron Beams.
A 2013 PRL from the Antwerp group [PDF][LINK] writes about the history of this subject:
"However, vortex beams of matter waves were not considered in detail until 2007 , when electron-vortex beams were first theoretically described... The first experimental demonstrations of electron-vortex beams were presented in 2010 [19,20]. Uchida and Tonomura produced their vortex beams using an approximation to a stepped, spiral phase plate, while Verbeeck et al. used a holographic reconstruction method [19,20].
Subsequent research has since developed electron-vortex beams much more broadly. Electron-vortex beams have been demonstrated for both detecting magnetic states within a material [20,21] and as a tool for manipulating nanoparticles . They have been produced with very high orders of OAM [23,24], and down to atomic size [25,26]. Alternative methods of production have also been developed. The holographic reconstruction setup used by Verbeeck et al.  was adapted for application within scanning transmission electron microscopy , while the previous work was better suited to conventional transmission electron microscopy."
2011: Our PRL article Relativistic electron vortex beams: Angular momentum and spin-orbit interaction, Phys. Rev. Lett. 107, 174802 (2011) describes the exact vortex Bessel-beam states of Dirac electrons. This provides a significant extension of the vortex-beam theory, including: (i) relativistic, (ii) spin, and (iii) nonparaxial effects. Our study demonstrates, for the first time, spin-orbit interaction phenomena inside free electrons. It also provides the general theory of angular and magnetic momenta of relativistic electrons including nonparaxial Berry-phase corrections.
