Abstract

Quantum field theory is a framework for interacting particles and provides a frame to understand our Nature in the fundamental level. Standard Model written in quantum field theory is the theory of all elementary particles and interactions besides the gravity. String/M theory has been studied as a consistent theory of quantum gravity. The progress in string theory led us to the realm of consistent quantum field theories in 5 and 6 dimensional space-time. In addition, a class of consistent 6-dimensional string theory without gravity, so-called little string theories, has emerged. These 6-dim theories have very rich structures with many implications in physics, geometry, black hole physics, and geometric Langlands program. In this seminar, I review some new ideas and discoveries and some further challenges.

Speaker Intro

I am a theoretical physicist working on quantum field theory and string theory. I have been educated in South Korea and United States. I worked as postdoctoral fellow and faculty member in US and also in South Korea. Recently I joined BIMSA in quantum field theory and string theory group. My research interests are also on cosmology, black holes, particle phenomenology, geometry, representation theory, vertex operator algebras, categorical symmetries, and number theory.

Member Seminar Intro

The BIMSA member seminar is a weekly event during which researchers engage in discussions about their extensive research interests, addressing a diverse audience that includes fellow researchers and all postdoctoral scholars within the institute. This forum provides a unique privilege and an invaluable opportunity for each research faculty member, serving as a speaker, to introduce their research field, promote the subject within the institute, and ignite the potential for future collaborations with other research groups within the institute.

The lecture format consists of a 30-minute colloquium-style presentation, thoughtfully tailored to be accessible to postdoctoral scholars and researchers from diverse disciplines within the institute. Following the presentation, a 15-minute discussion session is anticipated, involving active participation from postdocs representing various fields.

It is mandatory for all postdocs at the institute to actively participate in this event. The enthusiastic involvement of faculty members is greatly valued and will prove mutually beneficial for both the speaker and the junior audience.
