A tutorial treatment of the main concepts of the physics of crystal surfaces. Emphasis is placed on simplified calculations and the corresponding detailed analytical derivations, that are able to throw light on the most important physical mechanisms. More rigorous techniques, which often require a large amount of computer time, are also explained. Wherever possible, the theory is compared to practice, with the experimental methods being described from a theoretical rather than a technical viewpoint. The topics treated include thermodynamic and statistical properties of clean and adsorbate-covered surfaces, atomic structure, vibrational properties, electronic structure, and the theory of physisorption and chemisorption. The whole is rounded off with new excercises.

The book is intended for graduate students and researchers who wish to master the main properties of magnetic materials in the bulk state and at the nanometric scale such as for thin films and multilayers. This textbook provides the theories and methods of simulation to study and to understand these properties in an explicit manner.In the first part of the book, the quantum theory of magnetism is presented while the second part of the book is devoted to the application of the theory of magnetism to surface physics. Numerous examples covering typical cases in ferromagnets, antiferromagnets, ferrimagnets, helimagnets, and frustrated spin systems are all illustrated. Fundamental surface effects are shown and discussed. Lastly, the spin transport is described — in which the basic formulation of the Boltzmann's equation is recalled — and the recent methods of Monte Carlo simulation to deal with the spin resistivity are explained.This book contains a large number of detailed solutions for the problems given in each chapter to help readers discover new related phenomena and applications, as well as an appendix on elements of statistical physics included at the end to make the book self-contained.

‘Basic Physics: Principles and Concepts’ is a book meant for students of physics from the late school to college levels, covering both general and advanced course materials. It is a great text on basic concepts in physics over a wide range of topics with a truly broad coverage, which makes it a source-book of unique value to students of physics – one that will be of use for teachers of the subject too. Students and teachers in related subjects like chemistry, biology, and the various engineering disciplines will also benefit greatly from it. The book is completely modern in approach, and is exhaustive and authentic. The presentation is exceptionally lucid, and captures the essential charm of physics. All the concepts are developed from elementary considerations, and are built up to quite advanced levels without loss of coherence, simplicity, or elegance. The mathematics is essentially at the high school level, and relatively advanced mathematical ideas have all been built up in a self-contained manner. What is the principle of similitude? What are polar and axial vectors? What is a wrench? How are sliding and rolling friction explained? What is an anharmonic oscillator? What is tidal force? How are the principal components of strain and stress defined? How does the time period of angular oscillations of a floating body depend on the metacentric height? What is boundary layer separation? What is the entropy principle? How does the Döppler formula look in the case of accelerated motion of the source and the observer? What is the relevance of diffraction in image formation? What is electrostatic shielding? What is the pathway of energy flow in an electrical circuit? What is ferromagnetism? What is back-EMF in a DC motor? What are metamaterials? What are the basic features of Rayleigh scattering? What is population inversion in laser operation? How are harmonic oscillators relevant in the explanation of the black body spectrum? What is relativistic aberration? What is spin-orbit coupling? What are the features of an op-amp? What is a SR flip-flop? For answers to all these and to a host of other relevant questions, you have to turn to the pages of this book. It has nineteen meticulously written chapters, systematically divided into sections and subsections, and a moderate number of well chosen problems with hints for their solution.
