Since 1996 the Schools/Conferences are held exclusively at the University of Maribor, under the organization of CAMTP - Center for Applied Mathematics and Theoretical Physics, every three years. The 6th School/Conference is the largest, according to the number of invited lec- turers (46), whilst it is second largest as to the number of other participants (about 62), and also according to the richness of the scientific and cultural programme, which you can see in the following pages of this Book of Programme. The character of our Schools/Conferences is strongly international, we have invited lecturers and participants from all over the world, from all continents, and the national component of the Slovenian participants in total (invitees and others) does not exceed 10%.

Dane Quinn Sergio Felicelli Committee Member Dean of the College Graham Kelly Craig Menzemer Committee Member Dean of the Graduate School Ernian Pan Marnie Saunders Committee Member Date Patrick Wilber Committee Member Kwek Tze Tan ii ABSTRACT This work describes an analytical framework suitable for the analysis of large-scale arrays of coupled resonators, including those which feature amplitude and phase dy- namics, inherent element-level parameter variation, nonlinearity, and/or noise. In particular, this analysis allows for the consideration of coupled systems in which the number of individual resonators is large, extending as far as the continuum limit corresponding to an infinite number of resonators. Moreover, this framework per- mits analytical predictions for the amplitude and phase dynamics of such systems. The utility of this analytical methodology is explored through the analysis of a sys- tem of N non-identical resonators with global coupling, including both reactive and dissipative components, physically motivated by an electromagnetically-transduced microresonator array. In addition to the amplitude and phase dynamics, the behavior of the system as the number of resonators varies is investigated and the convergence of the discrete system to the infinite-N limit is characterized. The equilibrium obtained by the array of resonators may be unique if the behavior of many identical or slightly different resonators in the population is small, such equilibrium is also called mono-stable equilibrium.

Here, quantum theory enables accurate Monte Carlo simulations of melting of argon under pressures up to 100 GPa that can challenge such experiments (picture designed by J. Wiebke). Objectives of Research Centre: Our objective is to advance and disseminate knowledge in the area of theoretical/computational chemistry and physics, and to maintain high international standards in this research field only matched by top research institutes world-wide. All objectives are clearly met, as we are (to our knowledge) one of the most productive research centres here in New Zealand, with truly outstanding performances by each of our staff members. Our research centre has not been without a Marsden grant running since it was established, and our articles appear regularly in top journals such as Physical Review Letters or Angewandte Chemie. The many high-standing international visitors who joined our centre in 2013, and the many invitations to international conferences received by our staff are a clear indication of our success. Our research centre is unique within New Zealand and perhaps the wider Australasian area.

We support the study of nonlinear systems and dynamics in an interdisciplinary research field and very interesting applications will be presented. We intend to provide a widely selected forum to exchange ideas, methods, and techniques in the field of Nonlinear Dynamics, Chaos, Fractals and their applications in General Science and in Engineering Sciences. The principal aim of CHAOS2020 International Conference is to expand the development of the theories of the applied nonlinear field, the methods and the empirical data and computer techniques, and the best theoretical achievements of chaotic theory as well. Chaotic Modeling and Simulation Conferences continue to grow considerably from year to year thus making a well established platform to present and disseminate new scientific findings and interesting applications.
