Hydrodynamic transport coefficients in relativistic scalar field theory

Hydrodynamic transport coefficients in relativistic scalar field theory.

Hydrodynamic transport coefficients may be evaluated from first principles in a weakly coupled scalar field theory at arbitrary temperature. In a theory with cubic and quartic interactions, the infinite class of diagrams which contribute to the leading weak coupling behavior are identified and summed. The resulting expression may be reduced to a single linear integral equation, which is shown t...

Transport coefficients of a relativistic plasma.

In this work, a self-consistent transport theory for a relativistic plasma is developed. Using the notation of Braginskii [S. I. Braginskii, in Reviews of Plasma Physics, edited by M. A. Leontovich (Consultants Bureau, New York, 1965), Vol. 1, p. 174], we provide semianalytical forms of the electrical resistivity, thermoelectric, and thermal conductivity tensors for a Lorentzian plasma in a mag...

The aim of these lectures is to provide a self-contained presentation of the general foundations of rela-tivistic transport theory with the aim to provide the theoretical tools for th...

Initial-Value Problem in Quantum Field Theory: an Application to the Relativistic Scalar Plasma

A framework to describe the real-time evolution of interacting fermion-scalar field models is set up. On the basis of the general dynamics of the fields, we derive formal equations of kinetic-type to the set of one-body dynamical variables. A time-dependent projection technique is used then to generate a nonperturbative mean-field expansion leading to a set of self-consistent equations of motio...
