EPJ ST Highlight – Observing Flows at a Liquid-Liquid-Solid Intersection
- Details
- Published on 21 June 2024
Experiments reveal how a liquid-liquid interface interacts with a moving contact line.
Most of us are familiar with the classic example of a liquid-gas moving contact line on a solid surface: a raindrop, sheared by the wind, creeps along a glass windscreen. The contact line’s movements depend on the interplay between viscous and surface tension forces - a relationship that has been thoroughly investigated in experimental fluid mechanics. In a study published in EPJ Special Topics (EPJ ST), Harish Dixit, of the Indian Institute of Technology Hyderabad, and his colleagues now examine the movements of a contact line formed at the interface between two immiscible liquids and a solid. The experiments fill a gap in fluid dynamics and suggest a mechanism for an imposed boundary condition that eludes mathematical description.

EPJ ST Highlight - CompactLight: Designing a Cost-Effective XFEL Facility
- Details
- Published on 10 April 2024
An international group of experts has produced a design for a free electron X-ray laser facility that is significantly smaller and cheaper than those that are currently in use.
Very many advances in structural science since the 1970s were made by probing materials with synchrotron radiation: that is, high energy X-rays generated through accelerating high-energy electrons. The latest generation of such sources, X-ray free electron lasers (XFEL) are far more powerful than their predecessors, but are only accessible to international consortia and a few rich countries because of their high cost. Now, an international group of experts have prepared a design for a more compact and cost-effective XFEL system, accessible to small countries and, perhaps, some individual laboratories. The design is published in EPJ Special Topics (EPJ ST).
EPJ ST Highlight - An exciting era for ultrafast science in France
- Details
- Published on 15 December 2023
Progress across five scientific topics currently being investigated by the French scientific network on ultrafast phenomena highlight both a rapid pace of discovery and emerging new directions of research.
From biochemistry to quantum mechanics, ultrafast phenomena can be found across a broad array of scientific fields. Now the subject of a rapidly expanding area of research, they describe how matter behaves over timescales ranging from picoseconds (thousandths of a nanosecond), down to attoseconds (billionths of a nanosecond).
Today, ultrafast processes are studied by a global community of scientists, who are dedicated to understanding the inner workings of matter, and exploring how they can be controlled and exploited for novel applications. In 2023, three researchers were awarded the Nobel Prize in Physics for their contribution to attosecond laser technology: clearly emphasising the growing relevance of the field.
EPJ ST Highlight - Capturing the evolution of complex quantum systems
- Details
- Published on 09 August 2023
Through a new survey, researchers show how mathematical representations named ‘tensor trains’ can help to capture and simulate the dynamics of evolving quantum systems across a range of different scenarios.
Many quantum systems are heavily influenced by their surrounding environments, making them incredibly challenging to describe theoretically. To capture the dynamics and evolution of these systems, researchers often use mathematical representations named ‘tensor trains’. Through new research published in EPJ ST, a team of researchers from four different institutions in France show how tensor trains can be implemented to describe and simulate quantum systems.
EPJ ST Highlight - Many-body interactions feel the heat: Introducing thermal field theory
- Details
- Published on 01 August 2023
Thermal field theory seeks to explain many-body dynamics at non-zero temperatures not considered in conventional quantum field theory.
Quantum field theory is a framework used by physicists to describe a wide range of phenomena in particle physics and is an effective tool to deal with complicated many-body problems or interacting systems.
Conventional quantum field theory describes systems and interactions at zero temperature and zero chemical potential, and interactions in the real world certainly do occur at non-zero temperatures. That means scientists are keen to discover what effects may arise as a result of non-zero temperature and what new phenomena could arise due to a thermal background. In order to understand this, physicists turn to a recipe for quantum field theory in a thermal background — thermal field theory.
In a new paper in EPJ ST, Munshi G. Mustafa, Senior Professor at the Saha Institute of Nuclear Physics, Kolkata, India, introduces a thermal field theory in a simple way weaving together the details of its mathematical framework and its application.
