Universal properties of Chaos and Hydrodynamics

Project description

A systematic study of the universal properties of hydrodynamics and quantum chaos

In physics and engineering, fluid dynamics is the subdiscipline of fluid mechanics that studies liquids and gases in motion. Lately, it has been used to describe the whirling dynamics of the quark–gluon plasma produced in heavy-ion collisions that take place in powerful particle accelerators. Furthermore, it can describe statistical fluctuations of physical properties near the quantum chromodynamics critical point. Fluid dynamics can also shed more light on the physics of quantum chaos. The EU-funded UniCHydro project will offer researchers the opportunity to expand their methodological skill set on fluid dynamics to analyse statistical fluctuations and chaotic quantum systems.

Objective

Fluid dynamics is an effective description that applies to a variety of physical systems such as the quark-gluon plasma produced in heavy-ion collisions at RHIC and LHC. Recently, it has become of foremost importance to develop a hydrodynamic theory that incorporates the effects of statistical thermal fluctuations of the background. With such a framework at hand, it would be possible to analytically access many physical situations where statistical fluctuations are dominant such as in turbulent flows and, for example, around the putative critical point in the phase space of Quantum Chromodynamics (QCD) at finite temperature and finite baryon density.

Another place where such considerations become relevant is in the physics of Quantum Chaos. Recent developments have shed new light into manifestations of many-body quantum chaos and have lead to the formulation of an effective theory for chaotic systems, albeit with a large number of degrees of freedom. Deviations from this limit seem to strongly indicate the necessity of including statistical fluctuations. Understanding these effects would help to classify the different universality classes of chaos to complete the survey of its manifestations.

The research proposal “UniCHydro” addresses several strategic aspects mentioned above related to universal properties of fluid dynamics and quantum chaos. The Experienced Researcher is an expert on Schwinger-Keldysh effective field theory techniques which constitute the starting point for developing this research proposal. The stimulating environments of MIT and the University of Florence will allow then the Experienced Researcher to acquire the new set of skills in analyzing statistical fluctuations and new competencies in quantum chaos which will be fundamental to enhance its career prospects and to become a mature and independent scientist.
