This book deals with the discovery and explanation of the quantum Hall effect and its fundamental principles. It is meant for undergraduate and graduate students of physics, engineering, and applied sciences studying condensed matter physics. Doctoral students and researchers of this subject will also find it equally useful. It begins with a historical overview of this effect wherein the experiment and the physical systems are described. It progresses to cover discrete symmetries like inversion symmetry, time reversal symmetry, particle-hole symmetry, and chiral symmetry. It also examines how the Hamiltonian transforms under such symmetry operations. Two 1D models, namely the Su-Schrieffer-Heeger (SSH) model and a Kitaev chain with superconducting correlations, are discussed too. Then, the quantum Hall effect in graphene is explained. Further, the spin Hall effect is studied which may have prospects of using graphene as spintronic devices. The book ends with a brief review on fractional quantum Hall effect.

This book presents the proceedings of the 9th edition of Research and Industrial Conclave (RIC 2024) held at the Indian Institute of Technology (IIT) Guwahati, from 9 to 11 August 2024. It features a diverse collection of peer-reviewed research articles, highlighting emerging trends and application-oriented studies across a broad spectrum of science and technology domains. Broadly, this book features research in Chemistry, Physics, Biosciences and Bioengineering, and Biomedical and Health Sciences, capturing the diversity and depth of interdisciplinary exploration. It captures the essence of modern interdisciplinary research and aims to inspire further investigation and collaboration among researchers, academicians, and industry professionals. The contributions in this book is of particular interest to scholars, early-career researchers, and professionals in the fields of applied sciences, engineering, biomedical innovation, materials research, and computational healthcare technologies.

The book is mainly designed for post-graduate students to learn modern-day condensed matter physics. While emphasizing an experiment called the ‘Quantum Hall effect’, it introduces the subject of 'Topology' and how the topological invariants are related to the quantization of the Hall plateaus.
