Quantum dynamics of periodically driven quantum mesoscopic vibrational systems

Mesoscopic vibrational systems are attracting much attention. They are studied in quantum cavity and circuit electrodynamics, quantum optomechanics, nanomechanics, and cold atom physics, to mention but a few. The issue of utmost current interest is the dynamics of such systems in a strong periodic field. The black-board lectures are intended to provide an introduction to some features of this dynamics. The first part will discuss the phenomena at the heart of quantum optomechanics: the heating, cooling, and excitation of vibrational systems by a field that creates new dissipation channels. The second part will introduce Floquet states, discuss Floquet dynamics of isolated nonlinear vibrational systems, and then dissipative Floquet dynamics, including such topics as quantum heating and quantum activation phenomena, which lie behind the switching of driven quantum vibrational systems between metastable vibrational states. Time permitting, the quantum phase transition in coupled vibrational systems will be discussed.

Nano- and Microscale Vibrational Systems: from Cars to Quantum Computers

Small vibrational systems have remarkable properties, which enable a broad range of applications and pose challenging physical, mathematical, and engineering problems. Some of these problems and the ways to approach them will be outlined. Time permitting, the relation to other disciplines, such as chemistry and population dynamics, will be discussed.
