The branch of physics which uses three basic laws namely electromagnetism, statistical mechanics and quantum mechanics, to understand the physical and behavioral properties of condensed matter is known as condensed matter physics. Condensed matter physics uses the elements of nanotechnology, chemistry, biophysics, materials science, etc. It has application in the areas of laser technology, quantum computation and semiconductor devices among many others. This book attempts to understand the multiple branches that fall under this discipline. Most of the topics introduced in it cover new techniques and the applications of the subject. This textbook attempts to assist those with a goal of delving into this complex field.
