Minijet Initial Conditions For Non-Equilibrium Parton Evolution at RHIC and LHC
Fred Cooper, Emil Mottola, Gouranga C. Nayak
An important ingredient for the non-equilibrium evolution of partons at RHIC and LHC is to have some physically reasonable initial conditions for the single particle phase space di…
Quantum dynamics of phase transitions in broken symmetry field theory
Fred Cooper, John F. Dawson, Bogdan Mihaila
We perform a detailed numerical investigation of the dynamics of broken symmetry field theory in 1+1 dimensions using a Schwinger-Dyson equation truncation scheme based on i…
Dynamics of the chiral phase transition in the 2+1 dimensional Gross-Neveu model
Fred Cooper, Van M. Savage
The phase diagram of the Gross-Neveu (G-N) model in 2+1 dimensions as a function of chemical potential and temperature has a simple curve separating the broken symmetry and unbroke…
Non-Zero Magnetic Screening Mass in QED and QCD at One Loop Level in Non-Equilibrium
Fred Cooper, Chung-Wen Kao, Gouranga C. Nayak
Using the Schwinger-Keldysh closed time path integral formalism we show that the magnetic screening mass in QED and QCD at one loop level is non-zero as long as the single particle…
Dynamics of broken symmetry lambda phi^4 field theory
Fred Cooper, John F. Dawson, Bogdan Mihaila
We study the domain of validity of a Schwinger-Dyson (SD) approach to non-equilibrium dynamics when there is broken symmetry. We perform exact numerical simulations of the one- and…
Infrared Behaviour of The Gluon Propagator in Non-Equilibrium Situations
Fred Cooper, Chung-Wen Kao, Gouranga C. Nayak
The infrared behaviour of the medium modified gluon propagator in non-equilibrium situations is studied in the covariant gauge using the Schwinger-Keldysh closed-time path formalis…
Periodic Solutions of Nonlinear Equations Obtained by Linear Superposition
Fred Cooper, Avinash Khare, Uday Sukhatme
We show that a type of linear superposition principle works for several nonlinear differential equations. Using this approach, we find periodic solutions of the Kadomtsev-Petviashv…
