Finite-temperature three-point function in 2D CFT

Three Point Functions at Finite Temperature

We consider the calculations of three-point functions at nite temperature as they are usually performed in the literature. We show that as normally used, the Imaginary-Time and the Real Time nite temperature formalisms calculate expectation values of retarded and time ordered three point functions respectively. We also present a relation between these quantities that shows that they are not gen...

Three-Point Functions at Finite Temperature

We study 3-point functions at finite temperature in the closed time path formalism. We give a general decomposition of the eight component tensor in terms of seven vertex functions. We derive a spectral representation for these seven functions in terms of two independent real spectral functions. We derive relationships between the seven functions and obtain a representation of the vertex tensor...

Black Holes and Finite-Temperature Field Theory in AdS/CFT

Testing for Gaussianity Through the Three Point Temperature Correlation Function

One of the crucial aspects of density perturbations that are produced by the standard inflation scenario is that they are Gaussian where seeds produced by topological defects tend to be non-Gaussian. The three point correlation function of the temperature anisotropy of the cosmic microwave background radiation (CBR) provides a sensitive test of this aspect of the primordial density field. In th...

Gluon Condensation at Finite Temperature via AdS/CFT

We consider dilaton back reaction to the AdS gravity system and find an exact solution with two parameters interpolating between the recently discovered Csaki-Reece solution and the wellknown AdS black hole solution. Since solution does not admit the Hawking temperature in generic parameter values, we define the temperature using the holographic correspondence of Stephan-Boltzmann law. We descr...
