Atomic and Molecular Physics: a primer (2nd revised and extened edition)
No full textThis second edition course text introduces the fundamental quantum physics of atoms and molecules. With revised and extended content, this book is the first volume in a series of three aiming to present a broad coverage of atomic, molecular, solid-state and statistical physics. Divided into three parts, the first provides a historical perspective leading to the contemporary view of atomic and molecular physics, outlining the principles of non-relativistic quantum mechanics. The second covers the physical description of atoms and their interaction with radiation, whilst the third deals with molecular physics. The book's pedagogical features include conceptual layout sections that define the goals of each chapter, a simplified but rigorous mathematical apparatus, and a thorough discussion of approximations used to develop the adopted physical models

Tight-Binding Theory of Native Point Defects in Silicon
No full textVacancies and self-interstitial defects in silicon are here investigated by means of semi-empirical quantum molecular dynamics simulations performed within the tight-binding model. We extensively discuss the process of formation and migration of native point defects and investigate their interaction and clustering phenomena. The formation of larger stable structures is further studied by combining tight-binding and Monte Carlo simulations.
Tight-binding simulation results provide a global picture for defect-induced microstructure evolution in bulk silicon. These results are consistent with state-of- the-art experimental data and elucidate many relevant atomic-scale mechanisms
