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.
