报告简介:

I will discuss the phase transition on the interface between the 2D Ising CFT and the tricritical Ising CFT, extending Cardy’s classic result on the boundary phase transition of 2D CFTs. I will show that there exists a critical point separating the ordered phase and disordered phase, which can be described by a novel conformal interface between 2D Ising CFT and tricritical Ising CFT. By studying the annulus partition function (thermal CFT on a line interval), it allows us to bootstrap the boundary state up to a few signs. The work is inspired by recent advances in the experimental realization of the 2D Ising and tricritical Ising models using Rydberg atom arrays. I will introduce a potential experimental realization of the above setup if time permits.
