Nonequilibrium Dynamics and Off-Shell Transport of Relativistic Quantum Fields
S. Juchem, W. Cassing, C. Greiner University of Giessen, 2 University of Frankfurt The dynamics of quantum many-body systems are a challenging task for far-from-equilibrium conditions as appearing in high energy heavy-ion collisions or cosmological problems. It is of fundamental importance to describe abinitio thermalization by taking into account all quantum aspects of the particles (or fields...
متن کامل46 v 1 2 1 Ja n 20 04 Nonequilibrium Quantum - Field Dynamics and Off - Shell Transport for φ 4 - theory in 2 + 1 dimensions ∗
We solve the Kadanoff-Baym equations for nonequilibrium initial configurations of the φ4-theory in 2+1 dimensions and compare to explicit solutions of generalized transport equations for the same theory. The latter transport equations are derived from the Kadanoff-Baym equation in a first order gradient expansion in phase space and explicitly retain the off-shell dynamics as inherent in the tim...
متن کاملAxiomatic, Parameterized, Off-Shell Quantum Field Theory
Axiomatic QFT attempts to provide a rigorous mathematical foundation for QFT, and it is the basis for proving some important general results, such as the well-known spin-statistics theorem. Free-field QFT meets the axioms of axiomatic QFT, showing they are consistent. Nevertheless, even after more than 50 years, there is still no known non-trivial theory of quantum fields with interactions in f...
متن کاملRelating on-shell and off-shell formalism in perturbative quantum field theory
In the on-shell formalism (mostly used in perturbative quantum field theory) the entries of the time ordered product T are on-shell fields (i.e. the basic fields satisfy the free field equations). With that, (multi)linearity of T is incompatible with the Action Ward identity. This can be circumvented by using the off-shell formalism in which the entries of T are off-shell fields. To relate onan...
