Journal Club

Target Group of Theoretical Physics Journal Club is PhD students and postdocs doing research on different topics of theoretical physics. Here we can meet to learn and discuss classical or topics of theoretical physics. Talks usually take place at Oseenska rummet (Ångström, 73121).

Searching for Axions and the String Axiverse in the Cosmo
Speaker: Luca Visinelli
Paper: https://arxiv.org/abs/1809.06382 by Luca Visinelli, Sunny Vagnozzi
Date: 30 November 2018, 1.30-3.00pm
Location: Oseenska Rummet Å73121
Abstract: The low-energy limit of several string theories feature what is known as the “axiverse”, a plethora of light axions with masses spanning various orders of magnitude. I will first discuss astrophysical and cosmological constraints on axions at either end of this spectrum, using data from the cosmic microwave background anisotropies and from the gravitational microlensing. I then show how to assess the string parameters using a series of Bayesian analyses that take into account current limits on the tensor-to-scalar ratio and the primordial isocurvature fraction.

The many faces of N=1*
Speaker: Jesse van Muiden
Date: 23 November 2018, 1.30-3.00pm
Location: Oseenska Rummet Å73121
Abstract: In this talk I will give the status of our latest findings concerning the rich space of vacua in N=1*. This is especially interesting because the theory has a confining phase and the supersymmetry allows us to study this phase in a controlled way. First I will give an overview of the construction of the N=1* theory and its vacua. Then I will move on to describe the newly found 10D supergravity dual. Finally I will report on forthcoming work in which we study the space of vacua and its phases through S^4 and line operators.

Date: 9 November 2018, 1.30-3.00pm
Location: Oseenska Rummet Å73121
Abstract: Even if AdS3/CFT2 holography has been intensively studied in literature, the construction of 2d CFTs in string theory is still rather obscure. In this talk I will discuss some insights in this direction coming from a new class of exact AdS3 solutions in massive IIA supergravity. Within this class, some of these 10d backgrounds are derived by uplifting particular warped AdS3 solutions in 7d and 6d gauged supergravities featuring respectively AdS7 and AdS6 asymptotics. In these cases the corresponding dual 2d SCFTs are realized as conformal defects within the higher-dimensional SCFTs dual to the asymptotics. I will discuss about the brane intersections underlying these solutions and, in particular, on how the emergence of AdS3 in massive IIA is deeply related to D2 branes. To support this statement I will present a very simple brane solution involving only D2 branes and O8 planes with near-horizon given by a warped product of AdS3 with a squashed 7-sphere as internal space. In spite of the simplicity of this supergravity solution, the construction of the dual SCFT 2d is quite problematic, therefore I will conclude discussing these issues and the possible strategies to get rid of them.

Topological classification of nodal electronic band structures based on space group symmetries (towards the homotopy classification of vector bundles with crystalline symmetries)
Date: 26 January 2018, 1.30-3.00pm
Location: Room Å3419
Abstract: I would like to first give the motivation from electronic band theory. This is the framework for (non-interacting) topological insulators and topological semimetals. Then I would review my heuristic approach on the topological classification of band structures which combines space group representation theory with the algebraic computation of Wilson loops. The idea is to use the Wilson loops as indicators of the different topological sectors. Then I would like to conclude with some conceptual questions that naturally arise from this heuristic approach and for which I don't have answers yet.

Finiteness of correlation functions and conformal anomalies
Paper: - https://arxiv.org/abs/1611.01367, by Vladimir Prochazka and Roman Zwicky
- https://arxiv.org/abs/1703.01239, by Vladimir Prochazka and Roman Zwicky
Abstract: We look at logarithmically divergent contact terms of correlators of composite operators in a generic QFT. Utilizing RG techniques,  the UV behaviour of these contact terms is analysed and criteria for their UV finiteness are derived. As a particular case it is shown that the 2-point function of energy-momentum tensor trace is finite. Consequences thereof are explored in the context of conformal anomalies. It is shown that the finiteness of implies existence of a scheme, where the R^2 anomaly vanishes along the RG flow. As another consequence we provide a manifestly positive, scheme and flow independent expression for the difference between the UV and IR value of the ☐R anomaly.
