10361-51502019-09-30T02:55:37Z False vacuum decay exact computation of the classical bounce Hasan, M M Tarique Momen, Professor Arshad Department of Mathematics and Natural Sciences, BRAC University Computation This internship report is submitted in a partial fulfillment of the requirements for the degree of Bachelor of Science in Physics, 2016 Cataloged from PDF version of internship report. Includes bibliographical references (page 51-52). This thesis reviews the exact numerical computation of the classical bounce solution in the false vacuum decay for a quartic scalar eld potential which is o set by an external source. The decay rate in a semiclassical analysis consists of a leading exponential contribution due to the classical action evaluated on the classical bounce solution as well as a prefactor of functional determinants due to quantum uctuations about the classical bounce solution. The equation of motion of the classical bounce solution is obtained using the Euler-Lagrange equation and is numerically solved using the shooting method and the nite-di erence method. The appendix reviews a computational technique for evaluating the functional determinants of one-dimensional operators via the Gel'fand- Yaglom theorem. M M Tarique Hasan B.
