Fermion Pair Production From an Electric Field Varying in Two Dimensions
نویسنده
چکیده
The Hamiltonian describing fermion pair production from an arbitrarily time-varying electric field in two dimensions is studied using a group-theoretic approach. We show that this Hamiltonian can be encompassed by two, commuting SU(2) algebras, and that the twodimensional problem can therefore be reduced to two one-dimensional problems. We compare the group structure for the two-dimensional problem with that previously derived for the one-dimensional problem, and verify that the Schwinger result is obtained under the appropriate conditions.

Schwinger Pair Production via Instantons in a Strong Electric Field
In the space-dependent gauge, each mode of the Klein-Gordon equation in a strong electric field takes the form of a time-independent Schrödinger equation with a potential barrier. We propose that the singleand multi-instantons of quantum tunneling may be related with the singleand multi-pair production of bosons and the relative probability for the no-pair production is determined by the total ...
متن کاملPair production of light pseudoscalar particles in strong inhomogeneous fields by the Schwinger mechanism
The Schwinger mechanism is a non-perturbative process by which an infinite number of zero frequency photons can produce an electron-positron pair. For example a constant electric field larger than O(1011V/cm) will decay into electron-positron pairs, according to the Schwinger pair production probability formula [1]. In this paper we consider the pseudoscalar-two-photon coupling. We find that th...
متن کاملImproved Approximations for Fermion Pair Production in Inhomogeneous Electric Fields
Reformulating the instantons in a complex plane for tunneling or transmitting states, we calculate the pair-production rate of charged fermions in a spatially localized electric field, illustrated by the Sauter electric field E0 sech (z/L), and in a temporally localized electric field such as E0 sech (t/T ). The integration of the quadratic part of WKB instanton actions over the frequency and t...
متن کاملStrange and charm quark-pair production in strong non-Abelian field
We have investigated strange and charm quark-pair production in the early stage of heavy ion collisions. Our kinetic model is based on a Wigner function method for fermion-pair production in strong non-Abelian fields. To describe the overlap of two colliding heavy ions we have applied the time-dependent color field with a pulselike shape. The calculations have been performed in an SU(2)-color m...
متن کاملExact Pair Production Rate for a Smooth Potential Step
We derive the exact rate of pair production of oppositely charged scalar particles by a smooth potential step φ(x) ∝ tanh kz in three dimensions. As a check we recover from this the known results for an infinitely sharp step as well as for a uniform electric field.
