Description for Introduction To Quantum Spin Systems
Paperback. The topic of lattice quantum spin systems is a fascinating and by now well established branch of theoretical physics. Based on a set of lectures, this book has a level of detail missing from others, and guides the reader through the fundamentals of the field. Series: Lecture Notes in Physics. Num Pages: 165 pages, 22 black & white illustrations, biography. BIC Classification: PHFB; PHFC; PHQ. Category: (G) General (US: Trade). Dimension: 234 x 158 x 10. Weight in Grams: 258.
