摘要:

此前在ABJM理论中识别出的可积边界态均为非手性。本文首次在SU(4)交替自旋链中提出手性可积边界态,来源于平面两环拉廷算符在标量领域的两环拉廷算符。利用非扭曲可积条件的充分条件,我们识别出特定两站点和四站点基态边界态为手性可积态。数值证据表明,其他基态不太可能是手性可积的。此外,我们计算了这些手性可积基态与物理上本征态的重叠。

英文摘要:

Previously identified integrable boundary states in ABJM theory are exclusively achiral. This paper presents the first chiral integrable boundary states in the $SU(4)$ alternating spin chain from the planar two-loop dilatation operator in the scalar sector. Utilizing a sufficient condition for the untwisted integrable condition, we identify specific two-site and four-site basis boundary states as chiral integrable states. Numerical evidence indicates that other basis states are unlikely to be chiral integrable. Furthermore, we compute the overlaps between these chiral integrable basis states and on-shell Bethe eigenstates.
