[Seminar] Vacua of Large-N QCD3 (Prof. Adi Armoni, Swansea University) , University of Sheffield, UK)

Title: "Vacua of Large-N QCD3"

Abstract: 3d QCD in the 't Hooft large-N limit admits a rich structure. In this talk I will review the dynamics of this theory and its vacuum structure.  I will also mention the gravity dual of the theory.

SYK Seminar, Part VI: JT Gravity 2/2 (Rotation Project)

As part of my rotation project I will give a series of introductory lectures on the SYK model. In Part VI, I continue my talk about black holes, 2d dilaton theory, JT gravity and Schwarzian theory. We will finally close the ark started in Part I by making contact with the IR limit of the SYK model.

SYK Seminar, Part V: JT Gravity 1/2 (Rotation Project)

As part of my rotation project I will give a series of introductory lectures on the SYK model. In Part V, I begin an interlude about black holes, 2d dilaton theory and JT gravity.

SYK Seminar, Part IV: Emergent IR Symmetry (Rotation Project)

As part of my rotation project I will give a series of introductory lectures on the SYK model. In Part IV, I discuss how conformal symmetry emerges in the infrared limit.

[Seminar] Resurgent Properties of Minimal Strings and Painlevé Equations (Mr. Roberto Vega, Instituto Superior Tecnico, University of Lisboa)

Title: "Resurgent Properties of Minimal Strings and Painlevé Equations"

Abstract: In this this talk we will introduce the concept of resurgence and how can it be applied to construct global, nonperturbative solutions. As complete examples, we will mention the cases of the Painlevé I and II, while we will end up by focusing on the current state of the Inhomogeneous PII and a q-deformed PII. All these equations (with the exception of the Inhomogeneous PII) appear in the context of Minimal Strings and represent interesting low-dimensional toy models of Quantum Gravity.

Seminar: Topological recursion for tensor models (Prof. Valentin Bonzom (LIPN - Combinatorics, Algorithms and Interactions - Paris University 13)

Title: Topological recursion for tensor models

SYK Seminar, Part III: Effective Action (Rotation Project)

As part of my rotation project I will give a series of introductory lectures on the SYK model. In Part III, I show how to derive the effective action for the master fields G and Σ directly from the partition function.

Seminar: Unitary matrix models (Mr. Neetu, IISER, Bhopal, India)

Title: Unitary matrix models

SYK Seminar, Part II: Melons (Rotation Project)

As part of my rotation project I will give a series of introductory lectures on the SYK model. In Part II, I will discuss the 2-point correlation function and how the large N diagrammatics reduce to iterated melon diagrams.
