Abstract:

In the third and final year of research on magneto-electric conversion of optical energy to electricity, several major project objectives were achieved in the areas of theory and experiment. This was chiefly the result of a breakthrough in understanding the reported enhancement of magneto-electric scattering and switching to computer codes based on Matlab to improve both the speed of computations and the time required to acquire data. On the theoretical front, a dressed state approach was successfully developed to analyze optical magnetization. The introduction of Matlab software resulted in significant speedup. Computational timescales for large matrix diagonalizations went from days to hours. Applied to atomistic models, these computations of induced dipole moments revealed that the family of nonlinearities of interest in this work arise from dynamic symmetry-breaking by the optical magnetic field.
