"Comments on abelian Higgs models and persistent order" by Zohar Komargodski, Adar Sharon, Ryan Thorngren and Xinan Zhou has received the Select label. Warm congratulations to the authors!
This paper deals with the question regarding deformations of trivial gapped phases within Quantum Field Theory. In fact, it gives an interesting demonstration of the fact that even simple bosonic systems can have anomalies of discrete symmetries. The existence of anomalies implies that the theory cannot be completely disordered with a trivial gapped phase without topological order. The authors specifically connect these results with possible strong coupling regions. Finally, the authors discuss the important implications regarding whether the symmetries can be disordered or not. The models they discuss also are relevant to condensed matter systems.
We are extremely pleased to announce that Austria will form the first national consortium to sponsor SciPost. Led by the FWF, this consortium includes the Universities of Graz, Innsbruck, Linz, Salzburg and Vienna, the Technical Universities of Graz and of Vienna, the Montanuniversität Leoben, the IST Austria, and the Austrian Academy of Sciences. The consortium will sponsor SciPost for a period of 5 years.
These resources will be entirely dedicated to furthering SciPost's mission to transform scientific publishing by providing a Genuine Open Access solution to researchers worldwide. Our operations naturally align with and fulfil the requirements of the ambitions formulated in Plan S from cOAlition S.
Many Austrian researchers have already adopted and contributed to the SciPost platform, and we hope that this mark of recognition from this consortium will encourage many more to join in and further fuel our expanding operations.
"Exotic criticality in the dimerized spin-1 X X Z chain with single-ion anisotropy" by Satoshi Ejima, Tomoki Yamaguchi, Fabian H. L. Essler, Florian Lange, Yukinori Ohta and Holger Fehske has received the Select label. Warm congratulations to the authors!
In this very well written paper, the authors provide a comprehensive study of the phase diagram of the dimerized spin-1 XXZ chain with single-ion anisotropy. In addition, the authors were able to validate their results by an extensive field-theory analysis as well as DMRG, which ensures a quantitatively correct phase diagram. Overall, this paper will not only be important as a theoretical contribution for theoretical quantum physics, but also for experimental studies concerning spin chain compounds.
"Mott-insulator-aided detection of ultra-narrow Feshbach resonances" by Manfred J. Mark, Florian Meinert, Katharina Lauber, Hanns-Christoph Nägerl has received the Select label. Warm congratulations to the authors!
This innovative paper shows a new way of studying bound states in atom-atom scattering, and gives an exact demonstrator on how to measure very narrow Feshbach resonances. Although the authors used cesium in their demonstrator, other atoms with complex and overlapping Feshbach spectra like dipolar lanthanides could also benefit from this study. In general, these results provide a powerful tool to identify and characterise narrow scattering resonances. Therefore, this research has the potential to improve the accuracy of coupled-channels calculations of molecular potentials, may lead to new ways for the field of spectroscopy, and can ultimately give a new impulse to the study of interacting quantum matter.
"Walking, Weak first-order transitions, and Complex CFTs II. Two-dimensional Potts model at Q>4" by Victor Gorbenko, Slava Rychkov, Bernardo Zan has received the Select label. Warm congratulations to the authors!
This theoretical high energy physics paper studies the slow Renormalization Group (RG) evolution using a 2D Potts model with Q > 4. First, the authors define new complex Conformal Field Theories (CFTs). Then, these new CFTs are used to develop a conformal perturbation approach that describe slow real coupling trajectories in the vicinity of these complex CFTs. The Potts model was used to develop these CFTs because, apart from its own significance, it serves as an ideal playground for testing this very general relation. Here, one will find a thorough discussion of all conceptual issues related to the topic, and the theories developed can be further used as a smoking gun for detecting walking in Monte Carlo simulations.
On 1st of November, the KNAW organized a meeting on Plan S for making Open Access a reality by 2020. At this meeting, Robert-Jan Smits, the driving force behind this plan, gave an enlightening presentation in which he singled out and strongly endorsed SciPost (from 2:00 on), calling it a "marvelous initiative".
Interestingly, he suggested that "Rhodium" was a more appropriate descriptor for SciPost than Platinum or Diamond. In his words, Rhodium is a "precious metal, which is rock solid, highly reflective, and can resist corrosion" and fits SciPost, "which deserves a classification of its own", better.
SciPost is very grateful for this greatly encouraging recognition, and will redouble its efforts in implementing the transition to Open Access by realizing its vision for the future: Plan SciPost.
"Monitoring continuous spectrum observables: the strong measurement limit" by Michel Bauer, Denis Bernard, Tony Jin has received the Select label.
When monitoring quantum observables with continuous spectrum, the internal system evolution can compete with the measurement process. This competition induces a peculiar stochastic dynamics of the systems states which needs to be deciphered. In this well written and didactic paper, the authors rigorously formulate this challenging problem and study strong measurement limits. The analysis developed in this paper is expected to motivate further mathematical work based on the author’s approach, and a discussion can be started in the field.
"Deep-learned Top Tagging with a Lorentz Layer" by Anja Butter, Gregor Kasieczk, Tilman Plehn and Michael Russel has received the Select label.
Deep learning techniques based on low-level detector output are a promising new way to identify patterns in proton collision data at the LHC. They will, for example, allow us to identify the elementary particles making up so-called jets. This paper introduces a novel tagger that can identify boosted decaying top quarks using a set of measured four-momenta. It first shows that such taggers will outperform established techniques in a realistic detector environment. In addition, it traces the relevant patterns to the particle masses involved, extracted through the appropriate Minkowski metric.
