EPJ Data Science Highlight - Identifying inequality in the velocity of cryptocurrency
- Details
- Published on 04 April 2025
Analysis of a new framework for tracking cryptocurrency velocity reveals deep inequalities, driven not just by wealth but by economic behaviours of individuals
The ‘velocity of money’ describes the number of times a unit of currency is used to purchase goods or services within a given time period – or in other words, the number of times that money is changing hands. The quantity is a key indicator of the behaviours of economies as a whole – but today, researchers are still uncertain as to how the concept translates to the fast-growing field of cryptocurrency.
Through new analysis published in EPJ Data Science, Francesco Maria De Collibus and colleagues at the University of Zurich investigate a newly developed framework for measuring the velocity of cryptocurrencies – named ‘MicroVelocity’. Their analysis reveals that many of the same inequalities in wealth distribution found in the economy as a whole are also reflected in MicroVelocity.

EPJ E Highlight - Understanding arrangements of suspended particles in reversing flows
- Details
- Published on 13 March 2025
Experiments reveal new insights into how suspended particles rearrange themselves when the flow direction of their suspending fluid is reversed
When particles are suspended in viscous fluids of the same density, their distribution becomes uneven as the fluid is subjected to straining flows. This affects the suspension’s viscosity, especially during flow reversals. Yet although this behaviour is well understood in steady, uniform flows, less is known about how the microstructures of fluid suspensions will evolve in more complex scenarios.
Through new experiments detailed in EPJ E, a team led by Irene Ippolito at the University of Buenos Aires and Georges Gauthier at the University of Paris-Saclay have uncovered new insights into this evolving structure when a suspension’s flow direction is periodically reversed within a narrow gap.
EPJ B Highlight - Exploring the high-temperature performance of cadmium chalcogenides
- Details
- Published on 13 March 2025
Through a combination of experimental and theoretical analysis, researchers have gained new insights into the thermal stability and degradation of cadmium chalcogenides at high temperatures.
Cadmium chalcogenides are an important family of materials in which cadmium (Cd) forms a chemical compound with either tellurium (Te), selenium (Se), or sulphur (S). These materials are known for their useful electronic properties, as well as their strong thermal stability and high natural abundance. Yet despite these useful properties, researchers still have much to learn about how cadmium chalcogenides perform at the high temperatures required for many practical applications
Through new analysis published in EPJ B, researchers led by Zalak Kachhia at Sarder Patel University, India, present a detailed exploration of the thermal properties of cadmium chalcogenides, revealing new insights into how these materials degrade above certain temperature limits.

EPJ Plus Focus Point Issue: Nonlinear optical systems and applications
- Details
- Published on 19 February 2025
Guest Editors: J. Mou and Q. Zhou
Nonlinear optical systems have played a key role in modern technology. Innovations in the field of nonlinear optics have driven the development of several applications in efficient optical communications, quantum computing, and precision sensing. In this Focus Point on Nonlinear Optical Systems and Applications, cutting-edge research on nonlinear optical systems is discussed in depth, which not only focuses on the nonlinear dynamical behavior and noise effects in optical fibers but also explores the construction and application of nonlinear optical systems. These studies are crucial to further promote the performance optimization of optical networks. It is worth mentioning that the nonlinear optical system can be used as a pseudorandom number generator, and the complex pseudorandom sequences can be well applied in cryptography. In the future, research on nonlinear optics is expected to realize more stable optical communication and further increase the communication speed.

EPJ A Topical Collection: The Nuclear Many-Body Problem
- Details
- Published on 19 February 2025
Guest Editors: David Blaschke, Hisashi Horiuchi, Peter Ring, Gerd Röpke
This Topical Collection of the European Physics Journal A is devoted to recent progress in the nuclear many-body problem. In particular, it aims at a comprehensive compilation of developments related to the work of a pioneer in that field, Peter Schuck, who passed away in 2022.
The Topical Collection is considered as addendum and continuation of the seminal textbook of P. Ring and P. Schuck on “The Nuclear Many-Body Problem”, where different concepts have been elaborated further within a broad international collaboration. For instance, the quasi-particle approaches in connection with nuclear superfluidity and cluster formation in nuclear systems, in particular alpha-particle condensation and quartetting at subsaturation densities, have been brought forward. These advances obtained in the nuclear many-body problem can also be applied to other systems, for instance to solid state physics.
The articles included in the Topical Collection are available here and are freely accessible until 31 March 2025. For further information read the Editorial.
