![]() Free Download Elements Of Green Function And Density Functional Theory English | 2025 | ISBN: 9819805791 | 663 Pages | PDF (True) | 16 MB If there were no Coulomb interaction among electrons, it would be relatively straightforward to solve the many-electron Schrödinger equation. It is, however, precisely this interaction that is at the heart of numerous fascinating phenomena in condensed matter physics such as superconductivity, Kondo physics, magnetism, etc. Due to the large number of electrons in a material being of the order of Avogadro's number, it is at present ― and perhaps in the foreseeable future ― not feasible or even desirable to solve the Schrödinger equation to obtain the many-electron wavefunction. Fortunately, a large number of important physical properties can be calculated without explicit knowledge of the wavefunction.Two of the most important formalisms for dealing with the many-electron problem which avoid a direct use of the many-electron wavefunction are the Green function and the density functional theory. Within the Kohn-Sham scheme the latter is used to calculate ground-state properties whereas the former for excitation spectra. The book presents the fundamentals of these two theories in detail with essential many-body tools, such as the occupation number representation and Grassmann algebra developed from scratch. Prior knowledge of many-body theory is not a prerequisite so that it is readable for final-year undergraduates and graduate students in physics and chemistry as well as researchers in the field of electronic structure and many-body theory. The book includes in the last chapter an exposition of a density-functional path for determining the Green function, a new formalism recently proposed by the author. The book should be a valuable companion for those embarking in the field of many-electron physics. ![]() Free Download Anurag Rathore, Andras Guttman, "Electrokinetic Phenomena: Principles and Applications in Analytical Chemistry and Microchip Technology" English | 2003 | pages: 491 | ISBN: 0824743067 | PDF | 4,9 mb Electrokinetic Phenomena emphasizes the impact of methods such as capillary zone electrophoresis, capillary electrochromatography, and capillary gel electrophoresis on the analysis of biomolecules.

English | 2008 | pages: 320 | ISBN: 0521873193, 0521694809 | PDF | 2,1 mb Proposals for power-sharing constitutions remain controversial, as highlighted by current debates in Iraq, Afghanistan, Nepal, and Sudan. This book updates and refines the theory of consociationalism, taking account of the flood of contemporary innovations in power-sharing institutions that have occurred worldwide. The book classifies and compares four types of political institutions: the electoral system, parliamentary or presidential executives, unitary or federal states, and the structure and independence of the mass media. The study tests the potential advantages and disadvantages of each of these institutions for democratic governance. Cross-national time-series data concerning trends in democracy are analyzed for all countries worldwide since the early 1970s. Chapters are enriched by comparing detailed case studies. The mixed-method research design illuminates the underlying causal mechanisms by examining historical developments and processes of institutional change within particular nations and regions. The conclusion draws together the results and the practical lessons for policymakers. ![]() Free Download Drink Your Garden: Recipes, Stories and Tips from the Simple Goodness Cocktail Farm by Belinda Kelly, Venise Cunningham English | March 25th, 2025 | ISBN: 1682688798 | 256 pages | True EPUB | 187.02 MB Zen and Tonic meets cottagecore with 100+ botanical cocktail recipes from farmer-bartender sisters whose style and originality is on display in this joyful book. ![]() Free Download Dream Weaver: Finding Strength & Purpose in Life's Twists and Turns by Jenny Jing Zhu English | March 25, 2025 | ISBN: 1964686024, 9781964686042 | True EPUB | 126 pages | 3.9 MB Jenny Jing Zhu is a first-generation Chinese immigrant and proud Asian American. At an early age it became clear she was cut from a different cloth, defying her parents' wishes and cultural expectations. From finding her first job at age six in the small rural village of Caolou to learning about the realities of entrepreneurship, life, and love in Bejing as an older teen, Jenny relied on her instincts to follow her dreams. After building a string of small businesses, she landed in San Francisco as a newly married twenty-six-year-old to embark on the most challenge-filled yet rewarding adventure of her life. |
