About the School


The Giambiagi Winter School is organized by the Physics Department of Exact and Natural Sciences School of the University of Buenos Aires, Argentina. The main purpose of the School is to offer graduate students and young researchers an up-to-date perspective given by world-recognized experts.

In 2016 Giambiagi Winter School will be devoted to Quantum Chaos & Control, and will take place from July 25th to July 29th.


Quantum Chaos & Control


Quantum mechanics, initially developed to explain the behavior of matter and its interactions with light on the scale of atoms and subatomic particles, turned out to be the most successful physical theory of the 20th century and the foundation of an ongoing technological revolution.

Due to the Heisenberg uncertainty principle, in quantum mechanics the notion of trajectory is lost. As a consequence, the classical concept of chaos becomes meaningless as well. The quantum manifestations of chaos and its semiclassical limit, a subject known as “quantum chaos”, have been explored for 40 years.

This research area has received increasing attention because of its relation to control, relaxation and thermalization processes in many-body systems. Chaos plays a fundamental role in the microscopic origin of irreversibility described by the second law of thermodynamics. In fact, entropy is a measure of disorder, and entropy increase is generated by a chaotic time evolution.

The control of microscopic systems in order to obtain a desired final state or a certain value of a physical observable represents a major present goal in the field of quantum technologies. This has led to the development of sophisticated techniques, known generically as “quantum control”. To assess the efficiency of any quantum-control protocol, especially in a many-body setting, the challenge posed by chaotic dynamics cannot be overlooked.

The main purpose of this School is to bring together these two fundamental aspects of quantum dynamics:

  1. I)The appearance of quantum chaos and an overview of the tools developed for its study

  2. II) The theory of quantum control, and in particular its application to quantum many-body systems.
