Holographic Superconductor for a Lifshitz fixed point
We consider black hole duals of Lifshitz-fixed points at finite temperature, which was constructed in a recent work arXiv:0909.0263. We develop holographic techniques from equilibrium, to transport and to superconductivity. E-mail:[email protected] E-mail: [email protected] E-mail:[email protected] 1
متن کاملHolographic Correlators in a Flow to a Fixed Point
Using holographic renormalization, we study correlation functions throughout a renormalization group flow between two-dimensional superconformal field theories. The ultraviolet theory is an N = (4, 4) CFT which can be thought of as a symmetric product of U(2) super WZW models. It is perturbed by a relevant operator which preserves one-quarter supersymmetry and drives the theory to an infrared f...
متن کاملProgress on Holographic Three-Point Functions
The gauge/gravity correspondence provides an excellent tool for obtaining relevant information about supersymmetric Yang-Mills (SYM) theories from the study of their dual supergravity backgrounds, which are generated by stacks of D-branes. The most celebrated duality—known as the AdS/CFT correspondence— relates the superconformalN = 4 SYM theory in four dimensions (in the planar limit and at la...
متن کاملHolographic Quantum Critical Transport without Self-Duality
We describe general features of frequency-dependent charge transport near strongly interacting quantum critical points in 2+1 dimensions. The simplest description using the AdS/CFT correspondence leads to a self-dual Einstein-Maxwell theory on AdS4, which fixes the conductivity at a frequency-independent self-dual value. We describe the general structure of higher-derivative corrections to the ...
متن کاملcritical point
We have extended our method of grouping of Feynman diagrams (GFD theory) to study the transversal and longitudinal Greens functions G ⊥ (k) and G (k) in ϕ 4 model below the critical point (T < T c) in presence of an infinitesimal external field. Our method allows a qualitative analysis not cutting the perturbation series. We have shown that the critical behavior of the Greens functions is consi...
