Topological defect lines in symmetric-product orbifolds and tensionless holography
We investigate certain maximally-symmetric realizations of topological defect lines in the symmetric-product orbifold CFTs. In the particular case when the seed CFT is taken to be the theory of four free fermions and bosons on a 4-torus, we identify the $mathrm{AdS}_3$ string worldsheet duals of various defect configurations in the 2d spacetime CFT.
