Improved 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 کاملEffects of nanosecond pulse electric fields on cellular elasticity.
We investigated the effects of a single 60 nanosecond pulsed electric field (nsPEF) of low (15 kV/cm) and high (60 kV/cm) field strengths on cellular morphology and membrane elasticity in Jurkat cells using fluorescent microscopy and atomic force microscopy (AFM). We performed force displacement measurements on cells using AFM and calculated the Young's modulus for membrane elasticity. Differen...
متن کاملASYMMETRIC ELECTRON PAIR PRODUCTION ON CARBON"t
The cross section for the reaction 7 + C -+e+ + e+ C has been measured for a series of kinematic points giving nuclear momentum transfers in the region 0.2 0.7 F -2 , with incident -photon energies in the region for photoproduction of the first two pi-nucleon resonances. Measurements were made, using asymmetric detection geome-try, of e3.ectron and positron cross sections for each point. The ch...
متن کاملPair production in inhomogeneous fields
We employ the recently developed worldline numerics, which combines string-inspired field theory methods with Monte Carlo techniques, to develop an algorithm for the computation of pair-production rates in scalar QED for inhomogeneous background fields. We test the algorithm with the classic Sauter potential, for which we compute the local production rate for the first time. Furthermore, we stu...
متن کاملFermion 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...
