AdS${}_3\times$S${}^3$ magnons in the symmetric orbifold

Matthias R. Gaberdiel, Dennis Kempel, Beat Nairz

The AdS${}_3\times$S${}^3$ excitations of string theory on AdS${}_3\times$S${}^3\times {\mathbb{T}}^4$ are identified with certain collective modes in the dual symmetric orbifold. Our identi…
