Past Activities
The 14th Kavli Asian Winter School on Strings, Particles and Cosmology
In the Thematic Program 2018 of Tohoku Forum for Creativity, String-Math 2018, the follow up event will be held from January 13–22, 2020
Information
The Kavli Asian Winter School (KAWS) on Strings, Particles and Cosmology is a pan-Asian collaborative effort of high energy theorists
from China, India, Japan and Korea to give young researchers in Asia an opportunity to come together and learn about the latest developments in high energy theory from leading experts on the subject.
This school is aimed towards advanced graduate students, postdoctoral fellows and active researchers in the field.
This is the 14th in a series of Asian Winter Schools that have been organized on a rotating basis among Japan, China, India and Korea.
We welcome students from all of these participating countries as well as students from outside.
All selected participants will be provided with accommodation (with three meals a day).
The venue of the school is Tohoku university. It is located in Sendai city which is a fascinating city to explore Japanese culture and cuisine.
In addition, the school includes an excursion (two-day trip) to Zao which is a nearby town famous for hot spring and skiing.
The 2020 School is generously supported by the Kavli foundation, with additional partial funding the Kavli Institute for the Physics and Mathematics of the Universe (IPMU), Tohoku Forum for Creativity (TFC),
Tohoku University, and Graduate Program on Physics for the Universe (GPPU), Tohoku University.
The previous Asian Winter Schools in this series have provided young researchers with opportunities for discussions with leading experts in different areas and also for
initiating collaboration with other young researchers belonging to the different participating countries. We hope the 2020 School will continue this tradition.

- Title
- Analytic and Lorentzian methods in Conformal Field Theory
- Syllabus
- I will give an introduction to recent structural developments in conformal field theory (CFT).
These developments rely on the deep analyticity properties of CFT in Lorentzian kinematics.
I will assume knowledge of basic facts of CFT in general dimension, including: the state/operator map, radial quantization, the operator product expansion, crossing symmetry and conformal blocks.
There are many excellent reviews of this background material.
I highly recommend Slava Rychkov's lectures arxiv.org/pdf/1601.05000.pdf and David Simmons-Duffin's lectures arxiv.org/pdf/1602.07982.pdf
I will also assume some familiarity with the basic AdS/CFT dictionary.
A nice introduction in the spirit of structural CFT properties is given in Joao Penedones' lectures arxiv.org/pdf/1608.04948.pdf
- Title
- Mathematical Physics
- Syllabus
- Lectures 1-3: Integrability (and Knots) from Chern-Simons Theory
I will discuss integrable models from the viewpoint of four-dimensional analogue of Chern-Simons theory, based on my recent works with Costello and Witten.
Lecture 4: Minimalistic Introduction to the Swampland
I will introduce the concept of the swampland, and discuss phenomenological/cosmological implications of some swampland conjectures.
- Reading list
- Lectures 1-3:
section 1-6 of arxiv.org/abs/1709.09993
section 2-3 of arxiv.org/abs/1908.02289
