Prof. Philip Kim (Harvard Univ.)
"This book is a very pedagogical book that can introduce various examples of topological electronic systems to the students who want to study modern condensed matter physics. In order to draw the conclusion regarding the topological order in zigzag graphene nanoribbons, the author introduces several key concepts of topological state of matter, including Berry phase, Chern number, superconductivity and quantum Hall effect, zero energy solitons. The book is suitable for a graduate-level textbook with many examples and well-designed self-study problems."
Prof. Lu J. Sham (USCD)
" I am very impressed by the topic and the range it covers. "
Prof. Jeong-Hun Han (SKKU)
"This book is written at the level accessible to advanced undergraduate students and above. It is extremely readable and covers basic concepts that have become essentials of modern condensed matter theory such as Berry phase, entanglement, and so on. I highly recommend it to those seeking a smooth entry into the modern condensed matter physics."
