Atom tweezer arrays reveal how phase transitions unfold in mesoscopic systems
on June 18, 2025 at 11:00 am
As the number of particles in a physical system increases, its properties can change and different phase transitions (i.e., shifts into different phases of matter) can take place. Microscopic systems (i.e., containing only a few particles) and macroscopic ones (i.e., containing many particles) are thus typically very different, even if the types of particles they are made up of are the same.

Scientists uncover magnetic-field control of ultrafast spin dynamics in 2D ferromagnets
on June 17, 2025 at 7:05 pm
A research team led by Prof. Sheng Zhigao from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, in collaboration with Prof. A.V. Kimel from Radboud University, has demonstrated that strong magnetic fields can effectively regulate laser-induced ultrafast demagnetization in a two-dimensional (2D) van der Waals (vdW) ferromagnet.

Physicists use 3D-printed spines to sculpt water surface through surface tension
on June 17, 2025 at 6:20 pm
Physicists at the University of Liège have succeeded in sculpting the surface of water by exploiting surface tension. Using 3D printing of closely spaced spines, they have combined menisci to create programmed liquid reliefs, capable of guiding particles under the action of gravity alone. This is a promising advance for microscopic transport and sorting, as well as marine pollution control. The research is published in the journal Nature Communications.
