Description
Conformal interfaces are attracting growing attention across quantum field theory, holography, and integrability. While interfaces in higher-dimensional gauge theories—such as gauge-group-changing interfaces in N=4 super Yang–Mills theories—have been studied extensively, much less is known about interfaces in symmetric orbifold conformal field theories.
Symmetric product orbifolds are a remarkable class of two-dimensional CFTs, sharing many features with large-N gauge theories and playing a central role in tensionless holography. In this talk, I will present a construction of interfaces between symmetric product orbifolds with different orbifold groups and discuss the computation of some key observables. I will also describe their holographic interpretation and explore connections to integrability. The exploration of these interfaces and their role in holography is only just beginning. Some future directions will be discussed at the end.
