反膜理论中的双瞬子

Dual Instantons in Anti-membranes Theory

A. Imaanpur, M. Naghdi

摘要:

本文对11维欧几里德超引力场的3-型势在斜向扰动的AdS_4 × S^7背景下的两种形式的解进行了讨论,得到了两个m^2=-2的标量模.在这种背景下,通过与四次相互作用共形耦合,可以求出标量方程的精确解。这些模在SO(8)等距群的SU(4)子群下是不变的,而在边界ABJM理论中没有相应的一维或二维SU(4)单重BPS算符。我们注意到在体中的斜抽效应下8_s和8_c表示的互换,提出反膜理论应该类似地从ABJM理论通过互换这些表示而得到。特别是,这使我们能够识别的两个标量模式的对偶边界算子。我们用对偶算符变形边界理论,考察了费米子场方程,并将变形理论的解与体理论的解进行了比较。

英文摘要:

We introduce two ansatzs for the 3-form potential of Euclidean 11d supergravity on skew-whiffed AdS_4 X S^7 background which results in two scalar modes with m^2=-2 on AdS_4. Being conformally coupled with a quartic interaction it is possible to find the exact solutions of the scalar equation on this background. These modes turn out to be invariant under SU(4) subgroup of SO(8) isometry group, whereas there are no corresponding SU(4) singlet BPS operators of dimensions one or two on the boundary ABJM theory. Noticing the interchange of 8_s and 8_c representations under skew-whiffing in the bulk, we propose the theory of anti-membranes should similarly be obtained from ABJM theory by swapping these representations. In particular, this enables us to identify the dual boundary operators of the two scalar modes. We deform the boundary theory by the dual operators and examine the fermionic field equations and compare the solutions of the deformed theory with those of the bulk.
