Quantum Physics I

Deepening of the concepts of quantum mechanics introduced in undergraduate course by considering condensed matter physical nano-systems. The physics describing those systems designed nowadays as nanophysics is a physics which elaborate its objects and study them based on the principles of quantum mechanics which is the fundamental background underlying the development of nanotechnologies. The concepts illustrated in this course will be the pre-requisite of many second year Master courses related to quantum engineering which allow you to start a fundamental PhD in this topic after the Master. A good knowledge in this field is also more and more essential for technological researches and development of nanodevices.

The course will be illustrated by applying fundamental principle to condensed matter quantum systems (calculation of eigenstates and their evolution, symmetry properties) and by considering examples taken from recent researches and by discussing prospects for quantum information technologies.
