We use exceptional field theory to compute Kaluza-Klein mass spectra around ${\rm AdS_{3}}$ vacua that sit in half-maximal gauged supergravity in three dimensions. The formalism applies to any vacuum that arises from a consistent truncation of higher-dimensional supergravity, no matter what symmetries are preserved. We illustrate its efficiency by computing the spectra of ${\cal N}=(2,0)$ and ${\cal N}=(1,1)$ six-dimensional supergravities on ${\rm AdS_{3}}\times S^{3}$ and of type II supergravity on ${\rm AdS_{3}}\times S^{3}\times S^{3}\times S^{1}$.

${\rm AdS_{3}}$ vacua 的 Kaluza-Klein 光谱法

我们使用例外场论来计算 ${\rm AdS_{3}}$ 真空周围的 Kaluza-Klein 质谱,该真空位于三维空间的半最大测量超重力中。形式主义适用于任何由高维超引力的一致截断引起的真空,无论保留什么对称性。我们通过在 ${\rm AdS_{3}} 上计算 ${\cal N}=(2,0)$ 和 ${\cal N}=(1,1)$ 六维超引力的光谱来说明其效率\times S^{3}$ 和 ${\rm AdS_{3}}\times S^{3}\times S^{3}\times S^{1}$ 上的 II 型超引力。
