David L. Sidebottom is Associate Professor in the Physics Department at Creighton University. He is an experienced teacher and has taught a wide variety of courses at both undergraduate and graduate level in subject areas including introductory physics, thermodynamics, electrodynamics, laser physics and solid state physics. He has taught a course on solid state physics since 2003, adapting and revising its content to reflect the broader themes of condensed matter physics beyond those of the conventional solid state. This textbook stems from that course.
