A textbook on the fundamentals of quantum mechanics, emphasizing the effects from electron angular momentum including spin. Sufficient historical context is provided to better explain the origins of several well-known concepts in quantum mechanics. For the serious student and researcher, full derivations of results are included, as well as a first time derivation and application of spin-dependent energy dissipation introduced and applied in several important technological areas including spin transfer torque, spin diffusion, and micromagnetics. For superconductors, a novel and thorough treatment is provided under the premise that the potential function originally introduced by Cooper is also spin dependent as evidenced more clearly today by experimental data. This enables more precise properties of the potential to be exploited, its connection to holes, and it is shown to lead directly to discontinuities in both heat capacity and electrical conductivity at critical temperature. Relativistic quantum mechanics is also fully derived from application of the special theory of relativity along with several consequences. For superconductors, the text introduces a relevant higher order correction from the Dirac equation to the theory of superconductors to demonstrate its impact. These topics and their unique presentations are found exclusively in this text on quantum mechanics.
About the AuthorEason, Kwaku: - The author, Kwaku Eason, earned a PhD in engineering from the Georgia Institute of Technology in Atlanta, GA, USA in the area of computational and theoretical electromagnetics and magnetism, applied to the development of magnetometers with significant small length scale features. His thesis fully combined micromagnetics with the Maxwell dynamical equations through the use of advanced numerical schemes. Additionally, he earned a Master's and bachelor of science (BS) from the Georgia Institute of Technology, as well as a BS in mathematics from Morehouse College, also in Atlanta, GA, USA. After obtaining his PhD, he moved overseas from the US to Singapore taking a position as a Research Fellow at the Data Storage Institute (DSI), located at the National University of Singapore. There, he developed novel modeling techniques for data storage channel models that could be exploited in developing and designing disk drive components as well as error correction coding strategies for a host of future data storage technologies. At DSI, he later went on to lead the Spintronics and Magnetism team within the Advanced Concepts and Nanotechnology group where his team initiated and began development of technologies (along with disk drive technologies) utilizing spin-transfer torque of both conventional spin polarizers and spin-orbit. He later went to San Jose, Ca, USA to join the Advanced Technology Organization of Western Digital Technology. There, he lead a team of computational modelers in areas spanning quantum mechanics, electromagnetics, micromagnetics, heat transfer, thermodynamics, and mechanics for the development of future disk drive storage technologies. During his time with WD, he was also invited to join the MINT Research Center at the University of Minnesota, co-leading an industry-academia joint project, as well as doing some teaching on topics in spintronics and magnetism within the ECE department. He is an expert in areas of solid state, quantum, electromagnetic, and spin-physics, and creating accurate grounded computational models describing systems based on this physics. He is also the founder of Symphonious Technologies, which focuses on data storage and data processing technology development, exploiting these areas of physics, while also moonlighting as a technical writer.
