This manuscript is a textbook for a graduate course in quantum mechanics.I have taught this course 15-20 times and gradually developed these notes. Orginally，I used as a text Quantum Mechanics by A.S.Davydov.When that fine book went out of print，I wrote these notes following a similar syllabus.It contains much new material not found in older texts. The beginning chapters follow a traditional syllabus.Topics include solving Schrodingers equation in one，two，and three dimensions.Approximate techniques are introduced such as（1）variational，（2）WKBJ，and（3）perturbation theory.Many examples are taken from the quantum mechanics of atoms and small molecules.Solid-state ex-amples include exchange energy，Landau levels，and the quantum Hall effect.later chapters discuss scattering theory and relativistic quantum mechanics.The chapter on optical properties includes both linear and nonlinear optical phenomena. Each chapter concludes with numerous homework problems.Preliminary versions of these lectures have been handed to several generations of graduate students.Their feedback has been invaluable in honing the material.
