Title: Spin chain from marginally deformed AdS{sub 3}xS{sup 3}

Abstract

We derive a spin chain Hamiltonian from a fast spinning string in the marginally deformed AdS{sub 3}xS{sup 3}. This corresponds to a closed trajectory swept out by the SU(2) or SL(2) spin vector on the surface of one-parameter deformed two-sphere or hyperboloid in the background of an anisotropic magnetic field interaction. In the limit of small deformation, a class of general Landau-Lifshitz equation with a nontrivial anisotropic matrix can be derived.

  • We apply the transformation of the mixing azimuthal and internal coordinate or the mixing time and internal coordinate to the 11D M theory with a stack of M2-branes perpendicular M2-branes, then through the mechanism of Kaluza-Klein reduction and a series of the T duality we obtain the corresponding background of a stack of D1-branes perpendicular D5-branes which, in the near-horizon limit, becomes the magnetic or electric Melvin field deformed AdS{sub 3}xS{sup 3}xT{sup 4}. We find the giant graviton solution in the deformed spacetime and see that the configuration whose angular momentum is within a finite region could have a fixedmore » size and become more stable than the pointlike graviton, in contrast to the undeformed giant graviton which only exists when its angular momentum is a specific value and could have arbitrary size. We discuss in detail the properties of how the electric/magnetic Melvin field will affect the size of the giant gravitons. We also adopt an ansatz to find the classical string solutions which are rotating in the deformed S{sup 3} with an angular momentum in the rotation plane. The spinning string and giant graviton solutions we obtained show that the external magnetic/electric flux will increase the solution energy. Therefore, from the anti-de Sitter (AdS)/conformal field theory (CFT) point of view, the corrections of the anomalous dimensions of operators in the dual field theory will be positive. Finally, we also see that the spinning string and giant graviton in the near-horizon spacetime of Melvin field deformed D5-branes background have similar properties to those in the deformed AdS{sub 3}xS{sup 3}xT{sup 4}.« less
  • We construct a one-parameter family of flat currents in AdS{sub 5}xS{sup 1} and AdS{sub 3}xS{sup 3} Green-Schwarz superstrings, which would naturally lead to a hierarchy of classical conserved nonlocal charges. In the former case we rewrite the AdS{sub 5}xS{sup 1} string using a new Z{sub 4}-graded base of the superalgebra su(2,2 vertical bar 2). In both cases the existence of the Z{sub 4} grading in the superalgebras plays a key role in the construction. As a result, we find that the flat currents, when formally written in terms of the G{sub 0}-gauge invariant lowercase 1-forms, take the same form asmore » the one in the AdS{sub 5}xS{sup 5} case.« less
  • We first apply the transformation of mixing azimuthal and internal coordinate or mixing time and internal coordinate to the 11D M-theory with a stack N M2-branes to find the spacetime of a stack of N D2-branes with magnetic or electric flux in 10 D IIA string theory, after the Kaluza-Klein reduction. We then perform the T-duality to the spacetime to find the background of a stack of N D3-branes with magnetic or electric flux. In the near-horizon limit the background becomes the magnetic or electric field deformed AdS{sub 5}xS{sup 5}. We adopt an ansatz to find the classical string solutionmore » which is rotating in the deformed S{sup 5} with three angular momenta in the three rotation planes. The relations between the classical string energy and its angular momenta are found and results show that the external magnetic and electric fluxes will increase the string energy. Therefore, from the AdS/CFT point of view, the corrections of the anomalous dimensions of operators in the dual SYM theory will be positive. We also investigate the small fluctuations in these solutions and discuss the effects of magnetic and electric fields on the stability of these classical rotating string solutions. Finally, we find the possible solutions of string pulsating on the deformed spacetimes and show that the corrections to the anomalous dimensions of operators in the dual SYM theory are non-negative.« less
  • We study a class of classical solutions for closed strings moving in AdS{sub 3}xS{sup 1} subset of AdS{sub 5}xS{sup 5} with energy E and spin S in AdS{sub 3} and angular momentum J and winding m in S{sup 1}. They have rigid shape with n spikes in AdS{sub 3}. We find that when J or m are nonzero, the spikes do not end in cusps. We consider in detail a special large n limit in which S{approx}n{sup 2}, J{approx}n, i.e. S>>J>>1, with (E+S/n{sup 2}), (E-S/n), (J/n), (m/n) staying finite. In that limit the spiky spinning string approaches the boundary ofmore » AdS{sub 5}. We show that the corresponding solution can be interpreted as describing a periodic-spike string moving in AdS{sub 3}-pp-wavexS{sup 1} background. The resulting expression for the string energy should represent a strong-coupling prediction for anomalous dimension of a class of dual gauge theory states in a particular thermodynamic limit of the SL(2,R) spin chain.« less
  • We study in more detail the dynamics of chiral primaries of the D1/D5 system. From the CFT given by the S{sub N} orbifold a study of correlators resulted in an interacting (collective) theory of chiral operators. In AdS{sub 3}xS{sup 3} SUGRA we concentrate on general 1/2 BPS configurations described in terms of a fundamental string. We first establish a correspondence with the linearized field fluctuations and then present the nonlinear analysis. We evaluate in detail the symplectic form of the general degrees of freedom in SUGRA and confirm the appearance of chiral bosons. We then discuss the appearance of interactionsmore » and the cubic vertex, in correspondence with the S{sub N} collective field theory representation.« less
