Vladimir Bashmakov et al. receive the Select label

15 April 2019

"Living on the walls of super-QCD" by Vladimir Bashmakov, Francesco Benini, Sergio Benvenuti, Matteo Bertolini has received the Select label. Warm congratulations to the authors!

This excellently written paper concerns the 3d theory that lives on the domain walls of SQCD with less flavors than colors. It contains nice insights into the interplay between 4d bulk physics and 3d worldvolume domain walls physics. In particular, the authors propose a class of three-dimensional Chern-Simons-matter theories to describe the effective dynamics on the walls. Moreover, they present several interesting results in the topic, including successful non-trivial cross-checks of their proposal. In addition, they also provide a review section that clarifies their presentation. Overall, these results will be useful in future explorations of 3d non-supersymmetric QFTs and their connections to 4d physics.

SciPost top of the class at Crossref metadata

27 March 2019

An independent study of scientific metadata collections has recently highlighted the quality of our publishing services. We cannot do better than quote the spontaneous communication we recently received from Dr Habermann:

I am a "metadata guy" in Boulder, Colorado and have recently been working to characterize scientific metadata collections in many repositories around the world. I recently took a look at the CrossRef Participation Reports and implemented a simple quantitative measure of completeness of these collections and a simple plot that compares completeness over time. I am using this approach to try to understand evolution of CrossRef metadata through time. As part of this work I looked at completeness as a function of collections size. The original dataset was a sample from CrossRef. I recently updated the sample to include all CrossRef members.

I am happy to let you know that SciPost has the most complete metadata of all 8670 CrossRef members with current collections of journal articles.

The attached Figure shows the data and you can see that SciPost clearly stands out. […]

Great work,

Readers can find more details of this study on Dr Habermann’s blog.

We are very grateful for this very interesting and rewarding piece of information, which, besides confirming the top-quality of our services, interestingly points to many aspects of metadata systems (ours and those of others) which can still be improved.

Michael M. Cawte et al. receive the Select label

"Snell's Law for a vortex dipole in a Bose-Einstein condensate" by Michael M. Cawte, Xiaoquan Yu, Brian P. Anderson, Ashton S. Bradley has received the Select label. Warm congratulations to the authors!

This paper provides a useful guide for the behaviour of vortex dipoles as they pass through interfaces of sharply changing density, including a thorough numerical study and consequent analysis. As part of this analysis, the authors compare the values of the reflection/refraction vs. incident angles in vortex dipoles with a Snell’s law-like analytical prediction, achieving good agreement between the two before and after the interface. However, the authors found that when passing near the interface the dipole can exhibit dynamics that depart significantly from standard ray optics, involving transient capture by the interface. They conclude that despite the added complexity, an analogue Snell’s law is still applicable for the incoming and outgoing dipole paths when interacting with a sharp interface. This interesting and thorough study could guide future experiments on vortices in flattened geometries.

"A classical density functional from machine learning and a convolutional neural network" by Shang-Chun Lin and Martin Oettel has received the Select label. Warm congratulations to the authors!

This brilliant paper presents an inspiring conceptual DFT study, using machine learning methods to approximate a classical density functional, obtaining precise data for density distributions in given external potentials. In addition, they relate these simulations to their theoretical considerations, which encompass a variety of elements from classical liquid state theory to machine learning techniques. Conceptually, this goes far beyond what has been done in electronic structure DFT using machine learning. The hybrid approach of the current paper gives much insight into the formal (analytical) structure of the attractive contribution to the excess free energy functional. With the increasing use of machine learning, this study points towards the future direction on how to use it in the field of DFT.

First Volume of SciPost Physics Proceedings

22 February 2019

This month we have published the first volume of SciPost Physics Proceedings. The conference covered in this issue is the The 15th International Workshop on Tau Lepton Physics (Amsterdam, 24-28 September 2018).

This is the fifteenth workshop of TAU series on physics of the tau lepton, its neutrino, and related processes. The goal of the workshop was to get theorists and experimentalists together to discuss recent progress in the field. New results from high energy machines (e.g LHC experiments: ATLAS, CMS, LHCb), low energy machines (BES-III and other) and B-factories (including Belle-2) will be presented as well as recent results from g-2 and neutrino oscillation experiments. The program also includes related subjects such as hadron cross section measurement at e+e- colliders, lepton universality puzzles in meson decays, searches for Lepton Flavour Violation in τ and μ decays and review talks on the future experiments.

The refereeing of resulting proceedings volume has been managed by our guest fellows Dr. Marcus Matthias Morgenstern and Prof. Olga Igonkina. It contains 53 articles covering topics related to the tau lepton, neutrino and the related processes and possible experiments to detect them.

Beenakker et al. receive the Select label

11 February 2019

"Electrical detection of the Majorana fusion rule for chiral edge vortices in a topological superconductor" by C. W. J. Beenakker, A. Grabsch and Y. Herasymenko has received the Select label. Warm congratulations to the authors!

This publication presents a highly novel approach to tackle the demonstration of non-Abelian fusion rules of Majorana zero-modes, which can open a new line of research in the field of Majorana zero-modes. Building on recent research, the authors study how the injection at the edge vortices in systems with chiral Majorana edges affect the non-local fermion parity, and are able to observe this behaviour in electrical measurements.The proposed experiments can be applied to hybrid topological insulator/superconductor systems, and can be an important next step in the rapidly developing field of topological superconductors.

"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.
