Query: Islands and complexity of eternal black hole and radiation subsystems
  for a doubly holographic model   We study the entanglement islands and subsystem volume complexity
corresponding to the left/ right entanglement of a conformal defect in
$d$-dimensions in Randall-Sundrum (RS) braneworld model with subcritical
tension brane. The left and right modes of the defect mimic the eternal black
hole and radiation system respectively. Hence the entanglement entropy between
the two follows an eternal black hole Page curve which is unitarity compatible.
We compute the volumes corresponding to the left and right branes with
preferred Ryu-Takanayagi (RT) surfaces at different times, which provide a
probe of the subregion complexity of the black hole and the radiation states
respectively. An interesting jump in volume is found at Page time, where the
entanglement curve is saturated due to the inclusion of the island surfaces. We
explain various possibilities of this phase transition in complexity at Page
time and argue how these results match with a covariant proposal qualitatively.
