This Topical Issue of EPJ B brings together a collection of articles on the recent progress of the theoretical aspects and application in statistical physics of complex systems.

A strong framework for comprehending the behavior of complex systems is provided by statistical physics. Complex systems have emergent properties, or global behaviors that result from local interactions but are difficult to reduce to their component parts. Numerous academic fields, including physics, biology, economics, and sociology, deal with complex systems. The brain's neural networks, ecosystems, social networks, financial markets, and even climate systems are a few examples. In this context, the main objective of statistical physics is to explain how microscopic interactions result in macroscopic properties like temperature, magnetization, or network connectivity. It accomplishes this by handling the numerous degrees of freedom present in complex systems using probabilistic techniques.

The articles selected in this volume provide a comprehensive survey of the recent and most relevant developments in statistical physics and its applications in the physical sciences and beyond. This collection balances traditional and novel topics, giving a voice to both well-established and emerging research thematics. We hope that the collection of papers selected in this Topical Issue could give a valuable snapshot of the present status in this rapidly expanding interdisciplinary research field. We expect that the theoretical physicists reading this collection should be able to determine which questions are still challenging and on the other hand, we expect that the experimental physicists may receive new suggestions and ideas for their measures.

All articles are available here and are freely accessible until 25 February 2025. For further information read the Editorial.
