This special issue examines the extensive landscape of research into tipping within complex systems, and provides guidance as to where the field will likely be headed in the future.
Complex systems can be found in a diverse array of real-world scenarios, but are unified by their ability to suddenly transition between drastically different patterns of behaviour. Known as ‘tipping,’ this type of transformation is generally triggered by small changes in the parameters of individual systems – whose effects can rapidly cascade to alter entire networks of interacting subsystems. This special issue of EPJ Special Topics explores the nature of tipping in complex systems through 21 new articles. Together, the studies reveal recent trends and directions of research within the field, and highlight the pressing challenges it will face in the future.

Water, regarded as the matrix of life, is an ubiquitous and peculiar liquid that exhibits a plethora of anomalous properties, both in its stable and metastable bulk states, which fostered a lot of experimental and theoretical studies. Less explored is the field of water and aqueous systems confined in nanoporous materials that, in addition to its fundamental interest, are present in a number of practical situations, including biological and separation processes and energy generation and storage, among others. These facts have triggered a vast amount of research that, so far, has not been conveniently reviewed.

A new collection of papers focuses on the theories and methodology of dynamical networks with a focus on neuroscience and Earth sciences, and climate systems.
A special issue of EPJ Special Topics, edited by Jürgen Kurths (Potsdam Institute for Climate Impact Research), Elbert E. N. Macau (Federal University of São Paulo), Antonio C. Roque (University of São Paulo) and Serhiy Yanchuk (Humboldt University Berlin) brings together a collection of papers focusing improving our understanding of the collective dynamics of complex systems. The special issue pays particular attention to the applications of this understanding in the diverse fields of neuroscience, climate modelling, and Earth science.

Today, Gaussian Processes data reconstruction is viewed as a vital tool in cosmology. Yet through new analysis of tensions in the value of Hubble’s constant, two researchers suggest that the approach may not be as valid as currently thought.
The technique of Gaussian Processes (GP) is widely used to reconstruct cosmological parameters, most notably the expansion rate of the universe, using observational data. For many cosmologists, the crowning achievement of this approach is its ‘model independence’ – meaning it can be applied universally across all models. Through new analysis published in EPJ C, Eoin Ó Colgáin at Sogang University, Seoul, and Mohammad Mehdi Sheikh-Jabbari at IPM, Tehran, use the Hubble constant (H0) to show that this may not be the case – and that it may be time to question the validity of model independence itself.
EPJ A Highlight - Celebrating the impacts of Jacques Raynal’s work in the development of nuclear reaction formalism, codes and analysis
- Published on 08 November 2021
This topical article edition of EPJ A is dedicated to the memory of French nuclear physicist Jacques Raynal, who passed away on April 10th, 2020.
It illustrates, through a series of peer-reviewed articles, the various facets of what Raynal and his colleagues accomplished, as well as the profound influence of his results in several domains of nuclear reactions, both for theory formalism and for the analysis and understanding of experimental observables. The articles also demonstrate how his work paved the way for the future development of concepts and numerical codes for nuclear reaction calculations.
EPJ C Highlight - The first black hole image: A gravitomagnetic monopole as an alternative explanation
- Published on 04 November 2021
The Event Horizon Telescope made science history when it captured the first image of the supermassive black hole in the galaxy M87. New research suggests alternative explanations for the massive compact object at the centre of this galaxy questioning if this could contain gravitomagnetic monopole.
The Event Horizon Telescope (EHT) has recently mapped the central compact object of the galaxy M87 with an unprecedented angular resolution. Though the remarkable breakthrough has been interpreted based on theory that M87 contains a rotating or “Kerr” black hole. New research published in EPJ C by Chandrachur Chakraborty and Qingjuan Yu at the Kavli Institute for Astronomy and Astrophysics, Peking University (KIAA-PKU), Masoumeh Ghasemi-Nodehi and Youjun Lu, at the National Astronomical Observatories of China, looks at possible alternative explanations for the image.
