Plasma effects on lifetimes and screening of Rydberg excitons
AbdAlGhaffar Amer, V. Walther, Francis Robicheaux
We simulate the effects of a neutral electron--hole plasma on Rydberg excitons in cuprous oxide (CuO), focusing on the validity of Debye screening and the role of plasma-induce…

Simulations and theory of power spectral density functions for time dependent and anharmonic Langevin oscillators
AbdAlGhaffar K. Amer, F. Robicheaux
Simulations and theory are presented for the power spectral density functions (PSDs) of particles in time dependent and anharmonic potentials including the effects of a thermal env…

Simulation of STIRAP from the 1S to the 2S states of the Hydrogen/Antihydrogen atoms
AbdAlGhaffar K. Amer, A. Capra, T. Friesen +4
Achieving a high population of antihydrogen/hydrogen atoms in the 2S level is essential for spectroscopy measurements testing similarities between matter and antimatter. We propose…
