Condensed matter physics is the field of physics that deals with the macroscopic and microscopic physical properties of matter. In particular, it is concerned with the condensed phases that appear whenever the number of constituents in a system is extremely large and the interactions between the constituents are strong. Condensed matter physics is the field of physics that deals with the macroscopic and microscopic physical properties of matter. Condensed matter physics is a branch of physics that deals with the physical properties of condensed phases of matter. Condensed matter physicists seek to understand the behavior of these phases by using physical laws. In particular, these include the laws of quantum mechanics, electromagnetism and statistical mechanics. Condensed matter physics is the subfield to physics that has the largest number of direct practical applications, and has a large overlap with chemistry, materials science, and electrical engineering. It is also an intellectually challenging field that is currently producing many advances in fundamental physics. This book is good appetizer for all students seeking orientation in this fascinating field of physics.
