Supersymmetric hydrodynamics from the AdS/CFT correspondence
نویسنده
چکیده
We compute holographically the dispersion relation for a hydrodynamic mode of fluctuation (the phonino) of the density of supersymmetry current in N = 4 SYM at strong coupling. The mode appears as a pole at low frequency and momentum in the correlator of supercurrents. It has a wave-like propagation, and we find its speed and coefficient of attenuation. 1Unité Mixte du CRNS et de l’Ecole Normale Supérieure associée à l’université Pierre et Marie Curie 6, UMR 8549.

Non - supersymmetric Deformation of the AdS / CFT Correspondence
We deform the AdS/CFT Correspondence by the inclusion of a non-supersymmetric scalar mass operator. We discuss the behaviour of the dual 5 dimensional supergravity field then lift the full solution to 10 dimensions. Brane probing the resulting background reveals a potential consistent with the operator we wished to insert. e-mail: [email protected], [email protected], n.evans@hep....
متن کاملSupersymmetric Defect Expansion in CFT from AdS Supertubes
The AdS/dCFT correspondence is used to show that a planar q-dimensional supersymmetric CFT defect expands, under the addition of electric charge and angular momentum, to a supersymmetric higher-dimensional defect of geometry Rq × C, where C is an arbitrary curve. The dual string theory process is the expansion of D-branes and fundamental strings into a supertube in an AdS background.

متن کاملLattice Gauge Theories and the Ads/cft Correspondence
This is the write-up of a set of lectures on the comparison between Lattice Gauge Theories and AdS/CFT results for the non-perturbative behaviour of non-supersymmetric Yang Mills theories. These notes are intended for students which are assumed not to be experts in L.G.T. For this reason the first part is devoted to a pedagogical introduction to the Lattice regularization of QCD. In the second ...
متن کاملFrom AdS/CFT correspondence to hydrodynamics. II. Sound waves
As a non-trivial check of the non-supersymmetric gauge/gravity duality, we use a near-extremal black brane background to compute the retarded Green’s functions of the stress-energy tensor in N = 4 super-Yang-Mills (SYM) theory at finite temperature. For the long-distance, low-frequency modes of the diagonal components of the stress-energy tensor, hydrodynamics predicts the existence of a pole i...
متن کاملA Very Introductory AdS/CFT
The AdS/CFT correspondence, conjectured by Maldecena in late 1997, has been playing an essential role in modern string theory. The original version of this gravity/gauge AdS/CFT correspondence states an equivalence between Type 2B string theory on AdS5 × S and N = 4 super Yang-Mills theory in 4D, under certain parameter region. Namely, for these two theories, the operator variables, physical st...
