Lett. 117, 015502 (2016)], have been highlighted by the editors as two separate Editors’ Suggestions.
Publication of a Letter is already a considerable achievement, as Physical Review Letters accepts fewer than 1/4 of submissions, and is ranked first among physics and mathematics journals by the Google Scholar five-year h-index. A “highlighted Letter” has additional significance, because only about one Letter in six is highlighted as a Suggestion due to its particular importance, innovation, and broad appeal. Suggestions are downloaded twice as often as the average Letter, and are covered in the press substantially more often. If Suggestions were a separate publication, they would have an Impact Factor of 13.

2014: Our paper (Imaging the dynamics of free-electron Landau states, P. Schattschneider, Th. Schachinger, M. Stoger-Pollach, S. Loffler, A. Steiger-Thirsfeld, K. Y. Bliokh, F. Nori, Nature Communications 5, 4586 (2014)) [PDF, Link] has been featured in the news by: 2Physics [PDF, Link], Daily News [PDF, Link], Phys.org [PDF, Link], EurekAlert! [PDF, Link], Nanowerk [PDF, Link], Science Newsline [PDF, Link], Science Daily [PDF, Link], and Innovations Report [PDF, Link] .
2014: Our work on Imaging the dynamics of free-electron Landau states [PDF, Link] has been featured as the first "Headline News" of the August 15, 2014, issue of "Physics World" [PDF, Link]. In our publication in Nature Communication, we report the real-space observation of Landau states and the internal rotational dynamics of free electrons. States with different quantum numbers are produced using nanometre-sized electron vortex beams, with a radius chosen to match the waist of the Landau states, in a quasi-uniform magnetic field. We observe that Landau modes with different azimuthal quantum numbers belong to three classes, which are characterized by rotations with zero, Larmor, and cyclotron frequencies, respectively. This is in sharp contrast to the uniform cyclotron rotation of classical electrons, and in perfect agreement with recent theoretical predictions.
2014: A recent prepint from a German group [Link] writes in the introduction that our 2007 PRL started the field of electron vortex beams. The quote from their introduction is this: "While plane-wave electrons were used in most previous studies, new types of electron vortex beams, called twisted electrons, can now be generated. These twisted electrons are characterized by the projection of orbital angular momentum m onto the beam's propagation axis, which is the topological charge of the vortex. Electron vortex beams were first predicted theoretically in 2007 [our PRL] in analogy to optical vortex beams and have been realized experimentally later on with m ~ 100 hbar and kinetic energies of several hundred keV. Twisted electrons have been used to reveal information on the chiral and magnetic structure of materials [16, 17], even down to the atomic scale [18, 19]. Moreover, they feature spin-orbit-coupling [20, 21] and a large orbital angular momentum induced contribution to the electron magnetic moment  that, e.g., modifies polarization radiation [22, 23]. In addition, the propagation of twisted electron beams in external electric or magnetic fields allows to study the vacuum Faraday effect , Larmor and Guoy rotation , and fundamental properties of quantized electron states in magnetic fields ."
2014: An article in Nature [PDF],[Link] lists our work as the starting point of the field of electron vortex beams. Many other articles also do this. Their text starts like this: "Electron vortex beams, also known as electron twisters, are quantum waves of electrons that have a rotational motion akin to that of the notional electron clouds orbiting atomic nuclei - except that there is no central Coulomb force to hold the electrons, so the quantum wave can travel along its axis of propagation as it rotates. These beams remained a theoretical novelty  until their experimental demonstration four years ago [2-4]. They have many interesting physical properties, including potentially high magnetic moments and their interaction with matter and electromagnetic fields ." Here,  refers to our work K.Y. Bliokh, Y.P. Bliokh, S. Savel'ev, F. Nori, Semiclassical dynamics of electron wave packet states with phase vortices, Phys. Rev. Lett. 99, 190404 (2007). [PDF][Link][arXiv]
2014: Another article in Applied Physics Letters http://scitation.aip.org/content/aip/journal/apl/104/4/10.1063/1.4863564 writes this: "Electron vortex beams were introduced a few years ago theoretically by Bliokh et al.  and subsequently observed experimentally by Uchida and Tonomura,  Verbeeck et al.,  and McMorran et al.  Vortex beams are characterized by a staircase-like wavefront and therefore by a phase singularity that is stable upon free propagation. 
These beams are creating a very large interest for both fundamental studies, since they are a discrete state and eigenstates of the orbital angular momentum (OAM),  and for application as promising tools for transmission electron microscopy (TEM),  among which the most remarkable is magnetic dichroism.  On the other hand, these beams have also been used to convey angular momentum to nanoparticles [9,10] and are predicted to be an essential element for the design of an electron spin polarizer.  " Here Ref  refers to the same PRL of ours, listed above.

During the decade 2003-2013, 18 of our papers are listed by ISI (Essential Science Indicators) as top 1% cited papers in all areas of Physics (i.e., including high-energy physics, astrophysics, condensed matter, AMO, biophysics, etc). Thirteen (13) of these top 1% cited papers were published during the period 2008-2013. Eight of these top 1% cited papers were published during the period 2011-2013.
The 5-year h-index of the PI is 28, over refereed papers from 2008-2013 (versus 50 on Google Scholar). These numbers are high, for a single PI, as can be seen by direct comparison with the total 2008-2013 journal article output of the major international physics collaborations: Belle (~400 authors) h=19; Ligo (~800 authors) h=22; and Atlas (~3,000 authors) h=28.
The PI was ranked third in the world (out of a total of 12,269 authors) in the Thomson Reuters Science-Watch census of authors in terms of contributions to quantum computing over the decade 1999-2009.
Science Watch (ScienceWatch.com, which is part of Thomson Reuters) performed an analysis [Link] of quantum computing research using superconducting qubits over the decade 1998-2008. This analysis indicates that our 2005 Physics Today article on superconducting qubits has made a significant contribution to this field. Moreover, according to ISI, our 2005 Physics Today (PT) article is among the most cited PT papers in the 14 years from 2000 to 2013.
Furthermore, according to the ISI "Essential Science indicators" [Link] our 2005 Physics Today article is also in the top 0.1% cited papers among all papers published in all areas of physics. Physics Today has a circulation of 100,000 readers. Our 2005 Physics Today article has been translated into Japanese (the journal Parity) and also into other languages.
That same analysis [Link] of quantum computing research using superconducting qubits over the decade 1998-2008, indicates that another one of our papers has had a significant impact in this field. This is the paper "Controllable coupling between superconducting qubits", published in Physical Review Letters in 2006.
ScienceWatch.com devoted a "Special Topics" on "Quantum Computers" [Link]. Science Watch selected the top 20 papers from a pool of 243 papers over a two-years period 2008-2009. One of these top 20 cited papers was our work on "Controllable coherent population transfers in superconducting qubits for quantum computing", published in 2008 in Physical Review Letters.

2013: Our preprint on "Vindicating Heisenberg" (arXiv:1308.4853) was featured in the Nov. 1, 2013, issue of Physics World. [Link] 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."

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.
