论文摘要
我们详细介绍了IIB弦理论的Orbifolds在$ ads_5 \ times s^5 $上的处理，并使用可集成性技术的双计理论。通过扭曲的自旋链，具有化学势的热力学伯特贝氏方程以及具有修改渐近性的$ y $ - $ y $ - $ y $ - $ y $ - $ t $系统的实施Orbifolds的实施，面临着字符串Sigma-Model的扭曲边界条件。这使我们能够始终如一地扭动量子光谱曲线，据信这曲线桥接了广告/CFT二元性的两侧。我们讨论$ PSU（2,2 | 4）$的Abelian Orbifolds，并处理$ \ Mathcal {n} = 2 $ supersymmetric $ \ mathbb {z} _2 $ -orbifolds和type 0b tybe 0b sy tyb ads_5 \ timess_5 \ times s^5 $的特殊情况。这为探测二元性的有效性并研究了非苏联对称ADS/CFT的长期稳定问题的途径。我们评论当前对此问题的理解，并指出此挑战的下一步。
We elaborate on the treatment of orbifolds of type IIB string theory on $AdS_5\times S^5$ and their dual gauge theories with integrability techniques. The implementation of orbifolds via twisted spin-chains, thermodynamic Bethe Ansatz equations with chemical potentials and $Y$- and $T$-systems with modified asymptotics is confronted with twisted boundary conditions of the string sigma-model. This allows us to consistently twist the quantum spectral curve, which is believed to bridge the two sides of the AdS/CFT duality. We discuss Abelian orbifolds of $PSU(2,2|4)$ and treat the special cases of $\mathcal{N}=2$ supersymmetric $\mathbb{Z}_2$-orbifolds and type 0B string theory on $AdS_5\times S^5$ as primary examples. This opens a pathway to probe the validity of the duality and to study the long-standing question of tachyon stabilisation in non-supersymmetric AdS/CFT. We comment on the current understanding of this issue and point out the next steps in this challenge.
