Type II Solutions on AdS$_3\times S^3\times S^3$ with Large Superconformal Symmetry

Understand

New local solutions in type II supergravity that are foliations of AdS$_3\times S^3\times S^3$ over an interval and preserve at least large $\mathcal{N}=(4,0)$ supersymmetry are found.

• Some cases have compact internal space, some not and one experiences an enhancement to $\mathcal{N}=(4,4)$.
• We present two new globally compact solutions with D brane and O plane sources explicitly, one in each of IIA and IIB.
• The former is part of an infinite family of solutions with D8/O8s back reacted on AdS$_3\times S^3\times S^3\times S^1$.
