A note on instanton effects in ABJM theory
We consider the quantum spectral problem appearing the Fermi gas formulation of the ABJM (Aharony-Bergman-Jafferis-Maldacena) matrix model. This is known to related to the refined topological string on local P1×P1 Calabi-Yau geometry. In the ABJM setting the problem is formulated by an integral equation, and is somewhat different from the one formulated directly in terms of the Calabi-Yau geome...
متن کاملHow to put the Bagger-Lambert theory on an orbifold : A derivation of the ABJM model
We consider taking an orbifold of the multiple M2-brane theory recently proposed by Bagger and Lambert. Starting from the large-n limit of the 3-algebra structure realized as volume-preserving diffeomorphims, we suggest a prescription to impose an orbifold condition on various fields. As a relatively simple but non-trivial example we study an abelian orbifold C/Zk, and illustrate how one can de...
متن کاملLarge D-instanton effects in string theory
By reduction along the time direction, black holes in 4 dimensions yield instantons in 3 dimensions. Each of these instantons contributes individually at order exp(−|Q|/gs) to certain protected couplings in the three-dimensional effective action, but the number of distinct instantons is expected to be equal (or comparable) to the number of black hole micro-states, i.e. of order exp(Q). The same...
متن کاملNew Instanton Effects in String Theory
An important non-perturbative feature of string theory or M -theory compactifications which preserve only N = 1 supersymmetry in four dimensions is that fundamental string worldsheet or brane instantons can sometimes generate an effective superpotential for the light chiral superfields that describe the classical moduli of the background. Such a superpotential drastically alters the low-energy ...
متن کاملLinking loops in ABJM and refined theory
We consider the link average of the half-BPS Wilson loop operators in N = 6 superconformal Chern-Simons-matter theory, which is called ABJM theory. We show that this loop average is reduced to a (super)matrix integral by the localization method, in a similar way to the bosonic U(N) Chern-Simons theory. Using this matrix integral, we compute the twoand three-link averages with an operator formal...
