Topological insulators are insulating in the bulk, but process metallic states present around its boundary owing to the topological origin of the band structure. The metallic edge or surface states are immune to weak disorder or impurities, and robust against the deformation of the system geometry. This book, the first of its kind on topological insulators, presents a unified description of topological insulators from one to three dimensions based on the modified Dirac equation. A series of solutions of the bound states near the boundary are derived, and the existing conditions of these solutions are described. Topological invariants and their applications to a variety of systems from one-dimensional polyacetalene, to two-dimensional quantum spin Hall effect and p-wave superconductors, and three-dimensional topological insulators and superconductors or superfluids are introduced, helping readers to better understand this fascinating new field.
This book is intended for researchers and graduate students working in the field of topological insulators and related areas.

This new edition presents a unified description of these insulators from one to three dimensions based on the modified Dirac equation. It derives a series of solutions of the bound states near the boundary, and describes the current status of these solutions. Readers are introduced to topological invariants and their applications to a variety of systems from one-dimensional polyacetylene, to two-dimensional quantum spin Hall effect and p-wave superconductors, three-dimensional topological insulators and superconductors or superfluids, and topological Weyl semimetals, helping them to better understand this fascinating field. To reflect research advances in topological insulators, several parts of the book have been updated for the second edition, including: Spin-Triplet Superconductors, Superconductivity in Doped Topological Insulators, Detection of Majorana Fermions and so on. In particular, the book features a new chapter on Weyl semimetals, a topic that has attracted considerable attention and has already become a new hotpot of research in the community.

Since 1978, when China embarked on a new period of economic reforms and introduced open door policies, it has experienced a great urban transformation. The role of transport has proved indispensable in this unprecedented rapid urbanisation and economic growth. As the first research-focused book dedicated to this important topic, the Handbook on Transport and Urban Transformation in China offers new insight into the various opportunities and challenges brought by fast-paced motorisation and urban development, and explores them in broad spatial-economic, environmental, social, and institutional dimensions. This collection is an informative and comprehensive reference for researchers and academics at all levels studying transport, urban planning, and geography. It will also help practitioners and consultants gain a deeper understanding of policy development and best practices, and international and domestic policy makers will find guidance in the implications and lessons proposed for future transport research, policy, and practice. Contributors include: M. Cao, X. Chen, C. Curtis, X. Fu, Y. Gao, Y. Gao, D. Gong, R. Hickman, S. Huang, Z. Kang, M.-P. Kwan, C. Liu, Y. Liu, P. Newman, Z.-R. Peng, D. Pojani, B. Quan, J. Scheurer, Y. Shen, K. Si, N. Ta, Y. Tang, A. Thomas, Y. Tian, H. Titheridge, S. Wang, Y. Wang, P. Wei, T.G. Wereta, A.R. Williams, J. Wu, D. Xu, J. Xu, R. Ye, P. Zhao, M. Zhang, X. Zhang, F. Zhen
