Viscosity of the Scalar Fields from the Classical Theory
We show how the resummation for time dependent quantities at high temperature can be performed with an effective classical theory. As an application we demonstrate that the leading term in the shear viscosity, which is related to the ρΦ2Φ2 spectral function can be calculated classically, either using classical linear response theory or from the classical Φ2 correlation function. The classical r...
متن کاملThe traversable wormhole with classical scalar fields
We study the Lorentzian static traversable wormholes coupled to quadratic scalar fields. We also obtain the solutions of the scalar fields and matters in the wormhole background and find that the minimal size of the wormhole should be quantized under the appropriate boundary conditions for the positive nonminimal massive scalar field.
متن کاملEnergy conditions and classical scalar fields
Attention has been recently called upon the fact that the weak and null energy conditions and the second law of thermodynamics are violated in wormhole solutions of Einstein’s theory with classical, nonminimally coupled, scalar fields as material source. It is shown that the discussion is only meaningful when ambiguities in the definitions of stress-energy tensor and energy density of a nonmini...
متن کاملClassical Model Theory of Fields
We begin with some thoughts on how model theory relates to other parts of mathematics, and on the indirect role of Gödel’s incompleteness theorem in this connection. With this in mind we consider in Section 2 the fields of real and p-adic numbers and show how these algebraic objects are understood model-theoretically: theorems of Tarski, Kochen, and Macintyre. This leads naturally to a discussi...
متن کاملSpectral functions for composite fields and viscosity in hot scalar field theory
We derive a spectral representation for the two-point Green function for arbitrary composite field operators in Thermo Field Dynamics (TFD). A simple way for calculating the spectral density within TFD is pointed out and compared with known results from the imaginary time formalism. The method is applied to hot φ4 theory. We give a compact derivation of the one-loop contribution to the shear vi...
