Two common threads run through this body of work: they involve various aspects of quantum and classical field theory; and the extensive use of mma. But it otherwise spans a broad range of subjects. We first show that, contrary to claims in the literature, fermions can definitely form bound states on kink-antikinks. Next we borrow techniques from perturbative quantum field theory to calculate the effective dynamics of the <i>n</i>-body problem in classical General Relativity, up to 퓞 [(<i>v</i>/<i>c</i>)<sup>4</sup>] beyond Newtonian gravity, where <i>v</i> is the typical speed of the <i>n</i> compact objects. Following that, we exploit the bosonized version of quantum electrodynamics in two dimensional Minkowski spacetime to solve the backreaction problem of fermion-antifermion pair production for two “capacitor” setups, i.e. with a initial electric field localized in space. Finally, we examine the rates of fermion-antifermions pair production due to the time dependent <i>U</i>[1] gauge vector potential around an oscillating solenoid and that of cosmic string loops. 2010 English text Case Western Reserve University School of Graduate Studies / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=case1275928471 http://rave.ohiolink.edu/etdc/view?acc_num=case1275928471 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
