Description
We present a closed-form expression for the contribution of surface defects to the supersymmetric Rényi entropy in six-dimensional (2,0) theories. Our results show that this defect contribution is a linear function of 1/n and is directly proportional to 2b-d_2, where b and d_2 are the surface defect Weyl anomaly coefficients. We also derive a closed-form expression for the defect contribution to the supersymmetric Casimir energy, which simplifies to -d_2 (up to a proportionality constant) in the chiral algebra limit. This talk is based on arXiv:2501.09498 with Zixiao Huang and Ma-Ke Yuan.
