Title: 非超对称弦的AdS真空

Abstract: Few vacua are known for the three tachyon-free non-supersymmetric string theories. We find new classes of AdS backgrounds by focusing on spaces where the equations of motion reduce to purely algebraic conditions. Our first examples involve non-zero three-form fluxes supported either on direct product internal spaces or on $T_{p,q}$ geometries. For the ${\mathrm{SO}}(16)\times{\mathrm{SO}}(16)$ heterotic string, we then develop a method to engineer vacua with the addition of gauge fields. A formal Kaluza--Klein reduction yields complete solutions on a broad class of coset spaces $G/H$, automatically satisfying the three-form Bianchi identities with $H$-valued gauge fields.

Abstract: 已知三种无快子的非超对称弦理论的真空状态很少。 我们通过关注方程运动简化为纯代数条件的空间，找到了新的AdS背景类别。 我们的第一个例子涉及在直积内部空间或$T_{p,q}$几何上支持的非零三形式通量。 对于${\mathrm{SO}}(16)\times{\mathrm{SO}}(16)$杂交弦理论，我们随后开发了一种方法，通过添加规范场来构造真空。 一种形式的Kaluza--Klein约化在广义的齐次空间$G/H$上产生了完整的解，自动满足带有$H$值规范场的三形式Bianchi恒等式。
