Recent advances in collective phenomena

Abstract

Complex systems are more than the sum of their parts. When an extensive number of constituents come together and interact, intriguing collective phenomena arise. The study of these phenomena impacts diverse research areas, reaching from socioeconomics to quantum technologies. It is beyond the scope of this or any issue to capture all the latest developments in this field. Rather, we dedicate this issue to Prof. Malte Henkel on the occasion of his 60th birthday and aim to capture the scientific activity surrounding him and that he has impacted in one way or another. To this end, we give a brief overview of Prof. Henkel's vita and subsequently summarize the different contributions to this special issue.
