This textbook represents a new approach in the teaching of quantum physics. The first seven chapters present nonrelativistic quantum mechanics and its interpretation as well as perturbations and scattering theory. They include Dirac's and Feynman's formalisms. The chapter on symmetry treats gauge transformations, too. The quantum theory of angular momentum includes the isospin of leptons and quarks. It uses as a new tool the graphical spin algebra. The second part of the book is devoted to quantum fields: Boson fields including Higgs fields, Dirac's theory of Fermion fields, quantum electrodynamic and quantum chromodynamics. A brief review is appended to raise the students' interests in quantum cosmology. The readers will also find many detailed worked examples and many problems to test their own understanding.

Structure-Preserving Algorithms for Oscillatory Differential Equations describes a large number of highly effective and efficient structure-preserving algorithms for second-order oscillatory differential equations by using theoretical analysis and numerical validation. Structure-preserving algorithms for differential equations, especially for oscillatory differential equations, play an important role in the accurate simulation of oscillatory problems in applied sciences and engineering. The book discusses novel advances in the ARKN, ERKN, two-step ERKN, Falkner-type and energy-preserving methods, etc. for oscillatory differential equations.The work is intended for scientists, engineers, teachers and students who are interested in structure-preserving algorithms for differential equations. Xinyuan Wu is a professor at Nanjing University; Xiong You is an associate professor at Nanjing Agricultural University; Bin Wang is a joint Ph.D student of Nanjing University and University of Cambridge.
