Recent developments in double-scaled SYK

• Kazumi Okuyama

Room: 8F Lecture theatre SYK model is an interesting toy model of holographic duality. In particular, the so-called double-scaled SYK (DSSYK), which is defined by taking a large N limit with the number p of the p-body interaction scaled as p=N^(1/2), has attracted a lot of attention recently since DSSYK is exactly solvable thanks to the underlying quantum group symmetry. In this talk, I will briefly review the recent developments in DSSYK.

Yang-Mills/QCD on R2xT2, adiabatic continuity, and eta' potential

• Yuya Tanizaki

Room: 8F Lecture theatre We show that 4d Yang-Mills/QCD can be semi-classically solved on R2xT2 with nontrivial 't Hooft flux. In this setup, 4d instanton splits into N center-vortex fractional instantons, and its dilute gas describes qualitative features of 4d confinement vacua via the adiabatic continuity. When we apply this technique to QCD with fundamental quarks, we can learn about the global structure of the eta' potential.
