Indian research team uses supercomputer to track microscopic mechanisms of turbulence in dusty plasmas
Researchers at the Indian Institute of Technology Jammu (IIT Jammu), in collaboration with the Indian Institute of Technology Kanpur (IIT Kanpur), used supercomputer simulations to study the origin of chaos in dusty plasmas. By tracking the motion of millions of individual particles, the study revealed how turbulent energy is transferred from large-scale vortices to microscopic thermal motion of particles, providing a new computational perspective for nuclear fusion plasma research and astrophysical process analysis. Plasma is often referred to as the fourth state of matter. Unlike solids, liquids, and gases, atoms in plasma are ionized, forming a system composed of positively charged ions and negatively charged electrons. When tiny solid dust particles enter the plasma, these particles absorb electrons and become negatively charged, subsequently undergoing complex interactions with surrounding particles to form dusty plasma.

Two IPP studies reveal edge turbulence mechanisms in fusion plasmas from first principles
On August 10, 2026, two research teams at the Max Planck Institute for Plasma Physics (IPP) independently published findings that, for the first time, explain key phenomena in the extremely thin edge layer of fusion plasmas starting from fundamental physics equations. Both papers were published in Physical Review Letters, with one highlighted as an editor's suggestion. For stable operation of a fusion power plant, two requirements must be met simultaneously: on the one hand, the plasma at temperatures of around 100 million degrees Celsius must be effectively confined to achieve fusion ignition conditions; on the other hand, the generated heat must be distributed over a sufficiently large area to prevent damage to the device walls from excessive local heat loads. Whether this conflict can be resolved depends largely on a region only a few centimeters thick at the plasma edge.
