Submissions are invited for a Topical Collection of EPJ B on Localized Waves in Complex Nonlinear Physical Systems.
Localized waves (such as solitons, breathers and rogue waves) are fundamental excitation modes in nonlinear physical systems and are widely found in various systems, including Bose–Einstein condensates, nonlinear optics, fluid dynamics, plasma physics, biophysics, and financial physics. With the continuous advancement of experimental techniques and deep learning methods, researchers are not only able to obtain exact solutions for localized waves in ideal integrable systems but also to realize or predict novel localized wave states in various real-world complex nonlinear physical systems (such as non-Hermitian systems, high-dimensional systems, and multi-component systems), thereby revealing their intrinsic properties.
In anticipation of the 8th Hubei Soliton Symposium, this special issue has been established to compile the latest theoretical findings and applied advancements regarding localized waves in complex nonlinear physical systems. We encourage research that reveals the formation mechanisms, stability, interactions, and control techniques of localized waves from an interdisciplinary perspective, thereby promoting the convergence of nonlinear physics and related disciplines. Topics of interest include, but are not limited to:

Submissions are invited for a Topical Issue of EPJ B on CompLex: Complexity Science for Legal Applications.
In recent years, the intersection of law, governance, and complexity science has emerged as a fascinating and important area of study (See CompLex: legal systems through the lens of complexity science for a recent review). Modern societies are regulated by intricate legal and governance systems that share many characteristics with complex adaptive systems traditionally studied in physics and mathematics. These include nonlinear effects, feedback loops, and emergent behaviors. As our world becomes increasingly interconnected and complex, there is a growing need to apply rigorous quantitative methods to analyze and improve our legal and governance frameworks. The study of social institutions and governance has historically been confined to philosophy and social sciences. However, interdisciplinary applications of physics and other hard sciences have had a profound impact on our understanding of complex systems in biology, economics, and other fields. It is now time to extend this approach to law and governance. For over a decade, complexity scientists have been turning their attention to societal issues, but it is only recently that important legal and political questions have been formulated in a language that science can comprehend and meaningfully address. While some barriers still exist, the time is ripe for a full-fledged cross-fertilization between law/governance, physics, and computer science.
