RESUMO:
This presentation delves into a significant phase transition from regularity to mixed behavior observed in a nonlinear dynamical system. I tackle this complex phenomenon by addressing a set of four fundamental questions – (1) Identification of an Order Parameter: I explore the identification of a key order parameter that delineates the transition from regular to mixed behavior within the system; (2) Discussion on Elementary Excitations: I delve into a detailed discussion on the elementary excitations within the system, shedding light on their role in the observed phase transition; (3) Characterization of Symmetry Breaking: I examine the process of symmetry breaking that occurs as the system undergoes the transition, offering insights into the mechanisms driving this transformative phenomenon; (4) Localization of Topological Defects: I analyze the localization of topological defects within the system, elucidating their significance in understanding the nature of the phase transition. This investigation focuses on a two-dimensional nonlinear mapping that preserves the area of the phase space. However, the methodologies and insights garnered from this study hold the potential for extension to a wide array of other dynamical systems.
