This comprehensive book delves into the fascinating world of quasiparticle properties of graphene-related materials. The authors thoroughly explore the intricate effects of intrinsic and extrinsic interactions on the material's properties, while unifying the single-particle and many-particle properties through the development of a theoretical framework. The book covers a wide range of research topics, including long-range Coulomb interactions, dynamic charge density waves, Friedel oscillations and plasmon excitations, as well as optical reflection and transmission spectra of thin films. Also it highlights the crucial roles of inelastic Coulomb scattering and optical scattering in the quasiparticle properties of layered systems, and the impact of crystal symmetry, number of layers, and stacking configuration on their uniqueness. Furthermore, the authors explore the topological properties of quasiparticles, including 2D time-reversal-symmetry protected topological insulators with quantum spin Hall effect, and rhombohedral graphite with Dirac nodal lines. Meanwhile, the book examines the gate potential application for creating topological localized states and shows topological invariants of 2D Dirac fermions, and binary Z2 topological invariants under chiral symmetry. The calculated results are consistent with the present experimental observations, establishing it as a valuable resource for individuals interested in the quasiparticle properties of novel materials.Contents: Preface Introduction (Chiun-Yan Lin, Ching-Hong Ho, Hsien-Ching Chung, Lu-Yao Wang, Chih-Wei Chiu, and Ming-Fa Lin) A Quasiparticle Framework of Science Researches (Chih-Wei Chiu, Hsien-Ching Chung, Chiun-Yan Lin, Ching-Hong Ho, Lu-Yao Wang, and Ming-Fa Lin) Coulomb Scattering of Quasiparticles (Chiun-Yan Lin, Ching-Hong Ho, Hsien-Ching Chung, Lu-Yao Wang, Chih-Wei Chiu, and Ming-Fa Lin) Multi-mode Friedel Oscillations and Static Charge Screenings in Layered Systems (Chiun-Yan Lin, Chih-Wei Chiu, Ching-Hong Ho, Hsien-Ching Chung, Lu-Yao Wang, and Ming-Fa Lin) Propagation of Low-Frequency Plasmons and e–h Excitations (Chiun-Yan Lin, Ching-Hong Ho, Lu-Yao Wang, Chih-Wei Chiu, Hsien-Ching Chung, and Ming-Fa Lin) Optical Scatterings in Layered Systems (Chih-Wei Chiu, Lu-Yao Wang, Hsien-Ching Chung, Ching-Hong Ho, Chiun-Yan Lin, and Ming-Fa Lin) Topological Origin of Gate-Induced Localized States in Graphene (Lu-Yao Wang, Ching-Hong Ho, Hsien-Ching Chung, Chiun-Yan Lin, Chih-Wei Chiu, and Ming-Fa Lin) Two-dimensional Dirac Fermions in Z2 Topological Phases (Ching-Hong Ho, Lu-Yao Wang, Hsien-Ching Chung, Chiun-Yan Lin, Chih-Wei Chiu, and Ming-Fa Lin) Zero-Mode Landau Level of 2D Massless Dirac Fermions (Ching-Hong Ho, Hsien-Ching Chung, Chiun-Yan Lin, Lu-Yao Wang, Chih-Wei Chiu, and Ming-Fa Lin) Spin-Polarized Magneto-Electronic Properties of Buckled Monolayer GaAs (Hsien-Ching Chung, Lu-Yao Wang, Chih-Wei Chiu, Ching-Hong Ho, Chiun-Yan Lin, and Ming-Fa Lin) Concluding Remarks (Chiun-Yan Lin, Lu-YaoWang, Ching-HongHo, Hsien-Ching Chung, Chih-Wei Chiu, and Ming-Fa Lin) Perspectives and Open Issues (Hsien-Ching Chung, Lu-Yao Wang, Chiun-Yan Lin, Ching-Hong Ho, Chih-Wei Chiu, and Ming-Fa Lin) Problems (Lu-Yao Wang, Hsien-Ching Chung, Ching-Hong Ho, Chiun-Yan Lin, Chih-Wei Chiu, and Ming-Fa Lin) Index Readership: Academic researchers and graduates in materials science and condensed matter.
