This textbook presents problems with detailed solutions showing how to apply quantum theory to modern physics. The text is divided in three parts, the first dealing with elementary particles, nuclei and atoms, the second presents quantum entanglement and measurement. Finally complex systems are examinated in depth. The aim of the text is to guide the student towards applying quantum mechanics to research problems. Advanced undergraduates and graduate students will find a rich and challenging source for improving their skills.This new edition has been extended with sections on neutrino oscillations, quantized vortices in Bose-Einstein condensates, quantum correlations in multi-particle systems, Bloch oscillations in periodic lattices and non-destructive quantum measurements.

The Quantum Mechanics Solver provides a unique illustration of the application of quantum mechanical concepts to various fields of modern physics. It encourages the reader to apply quantum mechanics to research problems in fields such as molecular physics, condensed matter physics or laser physics. Advanced undergraduates and graduate students will find this book a rich and challenging source of material for further exploration.
