Description

This Advanced Research Workshop is of multidisciplinary character and aims bringing together various ideas and expertizes from the area of contemporary physics which is called complex system physics. In recent years application physics (especially such its areas as nonlinear dynamics and statistical physics) gained multidisciplinary character and is applied for the study of various problems of non-physical nature. In particular, research tools and ideas of physics have been applied to such areas as seismology, catastrophe theory, epidemiology, medicine, environmental sciences, economy and finances. Specially, in this context application of the theoretical research tools of physics to economics and finance has gained rapid development by penetrating almost all areas of the contemporary economic and financial sciences. Another important phenomenon of nonlinear dynamics which has become multidisciplinary field and found application in ecology, medicine, biology, seismology and finance is so-called theory of self-organized criticality. Currently it is being applied to prediction of earthquakes, financial crushes, spreading of epidemics etc. Also, study of complex systems is being important in so-called mesoscopic scale including nanoscale systems and quantum information. Importance of these systems is mainly caused by their direct relation to emerging area of modern technologies, so-called nanotechnologies. Mesoscopic systems have been the subject of intense interest in physics for well over a decade. The activity has been driven in large part by tremendous advances in the science of engineered materials as well as innovative probes to study their physics. This has resulted in wide-ranging applications in device physics which, in turn, make these systems attractive not only to explore fundamental questions but from intriguing practical issues such as nanomechanics and quantum computing. Briefly, mesoscopic refers to behavior in systems which are larger than atomic scales but are small enough that quantum effects are still important. This definition carries over to a variety of experimentally realized systems such as quantum dots, quantum wires, atoms in cavities, on surfaces and in optical lattices, ultra-cold atomic gases and nano-structures. They can be directly or indirectly used for generation quantum functional materials and nanoscale devices. Studying of such systems requires taking into account their complex and, in many cases, disordered nature. Finally, last topic, which is also important subject of the complex system physics quantum information, which unites several subfields as quantum computation, quantum cryptography, quantum teleportation etc. At present quantum cryptography is being considered as one of the powerful tools to be used in information security. Thus all the above issues of the nonlinear dynamics and complex system physics will be discussed from the viewpoint of their application in environmental studies, social sciences, economy and security. In keeping with this general motivation, the main purpose of the workshop is to focus on a variety of the less explored and newly appeared aspects of the complex system physics and nonlinear dynamics with special attention on disordered systems, self organized criticality, econophysics, nonlinear environmental dynamics, mesoscopic dynamics, particle and information transport in nanostructures, quantum functional materials and quantum information. Many of the key speakers have worked on other aspects, such as application of tools of the nonlinear physics to modeling of biological processes, earthquakes, spreading of epidemics, financial crashes and other processes in complex systems explicitly represented in the list of talks. These additional perspectives will be brought out in discussion panels which will intersperse groups of talks. These forums will be focused around questions arising from the talks. The format has proved particularly useful in relating the topics, in a broader sense, to the interests of participants from partner countries. This is fully in keeping with the additional mission of the workshop of encouraging young scientists from these partner countries to participate and collaborate on these and related topics.
