We study " fuzzy funnel " solutions to the non-Abelian equations of motion of the D-string. Our funnel describes n 6 360 coincident D-strings ending on n 3 6 D7-branes, in terms of a fuzzy six-sphere which expands along the string. We also provide a dual description of this configuration in terms of the world volume theory of the D7-branes. Our work makes… (More)

Abstract: In this article we study a pp-wave limit of the Lunin-Maldacena background. We show that the relevant string theory background is a homogeneous ppwave. We obtain the string spectrum. The dual field theory is a deformation of N = 4 super Yang-Mills theory. We have shown that, for a class of operators, at O(g YM) and at leading order in N , all… (More)

We review the derivation of a noncommutative version of the nonlinear sigma model on CP and it’s soliton solutions for finite θ emphasizing the similarities it bears to the GMS scalar field theory. It is also shown that unlike the scalar theory, some care needs to be taken in defining the topological charge of BPS solitons of the theory due to nonvanishing… (More)

The recently constructed Lunin-Maldacena deformation of AdS5 ×S5 is known to support two inequivalent Penrose limits that lead to BPS pp-wave geometries. In this note, we construct new giant graviton solutions on these backgrounds. A detailed study of the spectra of small fluctuations about these solutions reveals a remarkably rich structure. In particular,… (More)

We extend the proposal for a detailed map between wrapped D-branes in Anti-de Sitter space and baryon-like operators in the associated dual conformal field theory provided in hep-th/0202150 to the recently formulated AdS4 × CP/ABJM correspondence. In this example, the role of the dibaryon operator of the 3dimensional CFT is played by a D4-brane wrapping a… (More)

We construct the giant graviton on AdS4 × CP out of a four-brane embedded in and moving on the complex projective space. This configuration is dual to the totally anti-symmetric Schur polynomial operator χR(A1B1) in the 2+1dimensional, N = 6 super Chern-Simons ABJM theory. We demonstrate that this BPS solution of the D4-brane action is energetically… (More)

In this article we consider gauge theories with a U(N) × U(N) gauge group. We provide, for the first time, a complete set of operators built from scalar fields that are in the bi fundamental of the two groups. Our operators diagonalize the two point function of the free field theory at all orders in 1/N . We then use this basis to investigate non-planar… (More)

We present an embedding of the three-dimensional relativistic Landau-Ginzburg model for condensed matter systems in an N = 6, U(N) × U(N) Chern-Simons-matter theory [the Aharony-Bergman-Jafferis-Maldacena model] by consistently truncating the latter to an Abelian effective field theory encoding the collective dynamics of O(N) of the O(N(2)) modes. In fact,… (More)

We show that the construction of vortex solitons of the noncommutative Abelian-Higgs model can be extended to a critically coupled gauged linear sigma model with Fayet-Illiopolous D-terms. Like its commutative counterpart, this fuzzy linear sigma model has a rich spectrum of BPS solutions. We offer an explicit construction of the degree−k static semilocal… (More)

Article history: Received 19 December 2013 Accepted 21 January 2014 Available online 31 January 2014 Editor: M. Cvetič Using Mikhailov’s map from holomorphic functions to supersymmetric D3-brane solutions, we show how to construct giant gravitons in AdS5 × S5 with toroidal topologies. In the 4 -BPS sector we show that these are always of the form K (S2 ×… (More)
