Title: Matrix Models and Topological Recursion

Abstract: Hermitian matrix models are simplest quantum gauge field theory, namely quantum gauge theory in zero dimensions, and their correlation functions can be computed by a mathematical framework, the so-called topological recursion. In this review talk, I first present properties of Hermitian matrix models such as the 1/N-expansion, Virasoro constraints, loop equations, and the associated spectral curve. I will then give a technical overview of how we can recursively solve the loop equations of Hermitian matrix models by utilising the geometry of the spectral curve. Collecting the key geometric features, I will define the topological recursion with great generalities which makes it possible to apply the topological recursion beyond Hermitian matrix models.

Ttile: Wilson Line Networks for Flat Space Holography

Abstract: Several years ago, a technique in AdS/CFT was introduced which relates conformal correlation functions to Wilson networks in the bulk. The question arises whether this tool can be implemented in related models of holography. In my talk I will present the results of my master thesis, where I attempted to generalize the above-mentioned tool to what is so far known about flat space holography.

Title: An Invitation to Topological String Theory

Abstract: I will introduce the beauty of interplay among quantum field theory in various dimensions. More concretely, I will give an elementary review of fascinating relations among topological A-models and B-models, Chern-Simons theory, Seiberg-Witten theory, and matrix models. This talk will be designed for nonexperts so everyone in theoretical physics is welcome to join, including students. Research talks with more technical details may follow next week (and onwards) if there are interests.

Prof. Seung-Hee Lee, Associate Professor, Sensory Processing Lab, KAIST

Unraveling cortical circuits for perceptual decision making Sensory information is a key environmental cue that makes animals guide their behavior. However, it is still unclear how cortical circuits permit appropriate responses to relevant sensory stimuli while inhibiting others. Here, we unraveled cortical circuits that are important for perceptual decision-making in mice performing Go/No-go tasks. We identified parietal and frontal circuits that show unique properties in integrating sensory information and guide action decisions. I will discuss how these circuits work in concert for animals to perform proper action decisions upon the sensory evidence.
