      abstract     = {The study of non-local operators in gauge theory and
                      holography, such as line-operators or interfaces, has
                      attracted significant attention. Two-dimensional symmetric
                      product orbifolds are close cousins of higher-dimensional
                      gauge theory. In this work, we construct a novel family of
                      interfaces in symmetric product orbifolds. These may be
                      regarded as two-dimensional analogues of Wilson-line
                      operators or Karch-Randall interfaces at the same time. The
                      construction of the interfaces entails the choice of
                      boundary conditions of the seed theory. For a generic seed
                      theory, we construct the boundary states associated to the
                      interfaces via the folding trick, compute their overlaps and
                      extract the spectrum of interface changing operators through
                      modular transformation. Then, we specialise to the
                      supersymmetric four-torus $\mathbb{T}^4$ and show that the
                      corresponding interfaces of the symmetric product orbifold
                      are dual to $AdS_2$ branes in the tensionless limit of type
                      IIB superstring theory on $AdS_3 \times S^3 \times
                      \mathbb{T}^4$.},
