Several models that explained the origin of astrophysical jets have been created over time with varying degrees of success! Surprisingly, none of them have used Landau states to explain the origin of the astrophysical jets, which are always formed in the vicinity of a bizarre object, such as a black hole or a neutron star. Among the exotic properties shared by these, one in particular is that they often have an extremely strong magnetic field, which is precisely the environment where the Landau states are present. The purpose of this work is then to examine the role that Landau States could play in explaining the origin of astrophysical jets. After having determined how Landau states behave in uniform varying magnetic fields, two models will be proposed: 1) a Quasi-Realistic Astrophysical Jet Model that will try to explain how an astrophysical jet could be formed in the atmosphere of a neutron star, and 2) a Quasi-Realistic Jet Propulsion Mechanism that will try to explain how photons could be emitted when the density in the Landau states changes in the vicinity of a neutron stars surface and propelled via the astrophysical jets formed in the atmosphere of the neutron star.

I especially want to thank my advisor, Prof. Peter J. Watson, for his guidance during my research and study at Carleton University. He taught me my first course when I initi ated this crazy adventure. Once successfully completed, he was so generous in sharing me his thoughts about the potential role that Landau States could play in explaining the origin of astrophysical jets. In this regard, he showed me all roads that allowed me to complete this project. His perpetual energy and enthusiasm in research had always motivated me. In addition, he was always accessible and willing to help his students with their research. The generous support from my employer CANARIE Inc. is greatly appreciated. In retrospect, I am amazed by the confidence of managers and colleagues. Without their great patience and support, my ambition to study at part-time would hardly be realized. My deepest gratitude goes to my wonderful spouse, my two adorable sons, as well as my family, for their unflagging love and support throughout my life; this dissertation would have been simply impossible without them.
