Fermion pair production in time-dependent fields
Particle production in classical bosonic fields is a topic of continuing interest in QED and QCD. In strong fields processes with multiple couplings to the classical field are not parametrically suppressed by powers of the coupling constant g. In the absence of an additional scale, they have to be taken into account to all orders. In the following let us consider fermion production based on the...
متن کاملFermion production in time-dependent fields
Institut für Theoretische Physik, J.W. Goethe-Universität, 60054 Frankfurt am Main, Germany and Institut de Recherches Subatomiques, 23 rue du Loess BP 28, 67037 Strasbourg Cedex, France (Dated: October 27, 2003) Abstract The exact fermion propagator in a classical time-dependent gauge field is derived by solving the equation of motion for the Dirac Green’s functions. From the retarded propagat...
متن کاملFermion Determinant Calculus
The path-integral of the fermionic oscillator with a time-dependent frequency is analyzed. We give the exact relation between the boundary condition to define the domain in which the path-integral is performed and the transition amplitude that the path-integral calculates. According to this relation, the amplitude suppressed by a zero mode does not indicate any special dynamics, unlike the anal...
متن کاملFermion determinant with dynamical chiral symmetry breaking
One -loop fermion determinant is discussed for the case in which dynamical chiral symmetry breaking caused by momentum dependent fermion self energy Σ(p2) take place. The obtained series generalizes the heat kernel expansion for hard fermion mass. PACS number(s): 03.65.Db, 11.10Ef, 11.30.Rd, 12.39.Fe In quantum field theory, 1-loop quantum correction of fermions is from fermion determinant. It ...
متن کاملSelf-consistent solution of phase separation with competing interactions.
We present a solution of a modified time-dependent Ginzburg-Landau equation in the limit of in6nite order-parameter dimension N. The scalar (N = 1) model is believed to describe phase separation in chemically reactive binary mixtures, block copolymers, and other systems where competing short-range and long-range interactions give rise to steady-state, spatially periodic structures. We present e...
