Schwinger-Dyson approach to non-equilibrium classical field theory
In this paper we discuss a Schwinger-Dyson [SD] approach for determining the time evolution of the unequal time correlation functions of a non-equilibrium classical field theory, where the classical system is described by an initial density matrix at time t = 0. We focus on λφ4 field theory in 1+1 space time dimensions where we can perform exact numerical simulations by sampling an ensemble of ...
متن کاملSchwinger-Dyson approach to color superconductivity in dense QCD
The problem of color superconductivity in dense QCD is reconsidered in the improved rainbow approximation to the Schwinger-Dyson equation. The effect of the unscreened magnetic modes of gluons on the value of the color condensate is studied. In particular, it is shown that, at sufficiently large values of the chemical potential, these modes lead to the enhancement of the superconducting order p...
متن کاملDyson - Schwinger Equation Studies
The dichotomy of the pion as QCD's Goldstone mode and a bound state of massive constituents is easily understood using the Dyson-Schwinger equations. That provides the foundation for an efficacious phenomenology, which correlates the pion's charge radius and electromagnetic form factor with its valence quark distribution function; and simultaneously provides a Poincaré covariant description of ...
متن کاملQuantum Hamiltonian reduction of the Schwinger model.
We reexamine a unitary-transformation method of extracting a physical Hamiltonian from a gauge eld theory after quantizing all degrees of freedom including redundant variables. We show that this quantum Hamiltonian reduction method su ers from crucial modi cations arising from regularization of composite operators. We assess the e ects of regularization in the simplest gauge eld theory, the Sch...
متن کاملSchwinger-Dyson Equlltion in Three-Dimensional Simplicial Quantum Gravity
We study the simplicial quantum gravity in three dimensions. Motivated by Boulatov's model which generates a sum over simplicial complexes weighted with the Turaev·Viro invariant, we introduce boundary operators in the simplicial gravity associated to compact orientable surfaces. An amplitude of the boundary operator is given by a sum over triangulations in the interior of the boundary surface....
