Book Description
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.

Book Description
Graphene-like materials have attracted considerable interest in the fields of condensed-matter physics, chemistry, and materials science due to their interesting properties as well as the promise of a broad range of applications in energy storage, electronic, optoelectronic, and photonic devices.The contents present the diverse phenomena under development in the grand quasiparticle framework through the first-principles calculations. The critical mechanisms, the orbital hybridizations and spin configurations of graphene-like materials through the chemical adsorptions, intercalations, substitutions, decorations, and heterojunctions, are taken into account. Specifically, the hydrogen-, oxygen-, transition-metal- and rare-earth-dependent compounds are thoroughly explored for the unusual spin distributions. The developed theoretical framework yields concise physical, chemical, and material pictures. The delicate evaluations are thoroughly conducted on the optimal lattices, the atom- and spin-dominated energy bands, the orbital-dependent sub-envelope functions, the spatial charge distributions, the atom- orbital- and spin-projected density of states, the spin densities, the magnetic moments, and the rich optical excitations. All consistent quantities are successfully identified by the multi-orbital hybridizations in various chemical bonds and guest- and host-induced spin configurations.The scope of the book is sufficiently broad and deep in terms of the geometric, electronic, magnetic, and optical properties of 3D, 2D, 1D, and 0D graphene-like materials with different kinds of chemical modifications. How to evaluate and analyze the first-principles results is discussed in detail. The development of the theoretical framework, which can present the diversified physical, chemical, and material phenomena, is obviously illustrated for each unusual condensed-matter system. To achieve concise physical and chemical pictures, the direct and close combinations of the numerical simulations and the phenomenological models are made frequently available via thorough discussions. It provides an obvious strategy for the theoretical framework, very useful for science and engineering communities.

Book Description
This thesis develops new techniques for simulating the low-energy behaviour of quantum spin systems in one and two dimensions. Combining these developments, it subsequently uses the formalism of tensor network states to derive an effective particle description for one- and two-dimensional spin systems that exhibit strong quantum correlations. These techniques arise from the combination of two themes in many-particle physics: (i) the concept of quasiparticles as the effective low-energy degrees of freedom in a condensed-matter system, and (ii) entanglement as the characteristic feature for describing quantum phases of matter. Whereas the former gave rise to the use of effective field theories for understanding many-particle systems, the latter led to the development of tensor network states as a description of the entanglement distribution in quantum low-energy states.

Book Description
Optical properties, particularly in the infrared range of wavelengths, continue to be of enormous interest to both material scientists and device engineers. The need for the development of standards for data of optical properties in the infrared range of wavelengths is very timely considering the on-going transition of nano-technology from fundamental R&D to manufacturing. Radiative properties play a critical role in the processing, process control and manufacturing of semiconductor materials, devices, circuits and systems. The design and implementation of real-time process control methods in manufacturing requires the knowledge of the radiative properties of materials. Sensors and imagers operate on the basis of the radiative properties of materials. This book reviews the optical properties of various semiconductors in the infrared range of wavelengths. Theoretical and experimental studies of the radiative properties of semiconductors are presented. Previous studies, potential applications and future developments are outlined. In Chapter 1, an introduction to the radiative properties is presented. Examples of instrumentation for measurements of the radiative properties is described in Chapter 2. In Chapters 3-11, case studies of the radiative properties of several semiconductors are elucidated. The modeling and applications of these properties are explained in Chapters 12 and 13, respectively. In Chapter 14, examples of the global infrastructure for these measurements are illustrated.
