Physicists capture the elusive plasma instability in unprecedented detail
“Shadowgraphy” allows scientists to visualize fluctuations in plasma density and measure filament instability. Credit: Imperial College London For the first time, scientists have “photographed” the rare plasma instability in which high-energy electron beams form in spaghetti-like filaments. A new study published in the Physical Review Letter outlines how high-intensity infrared lasers were used to generate filamentation instability. This is a…

Physicists find unexpected electron crystals in new ultra-thin materials
This graphic visualizes how electrons behave as solids (left, glacier-like structure) or liquids (river-like structures) depending on the voltage applied to new material cooled to ultra-low temperatures similar to space. Credits: Michael Hurley and Sampson Wilcox/Research Laboratory of Electronics MIT physicists report the unexpected discovery of electrons forming crystal structures in a material that is a billionth of thickness. This…

Physicists introduce percolation model to explain word puzzle solving behavior
Sample realization of L = 20, pb = 0.2. Black sites are black, empty sites are white, and occupied sites have symbols and text. All site segments surrounded by black sites are words. letters a, b,. . . indicates the cluster formed by the resolved word, and the @ symbol indicates an occupied site that does not belong to the…

Physicists measure quantum geometry for the first time
Strategies for measuring quantum geometric properties in condensed matter. Credit: Nature Physics (2024). DOI: 10.1038/s41567-024-02678-8 For the first time, MIT physicists have measured the geometry, or shape, of electrons in a solid at the quantum level. Scientists have long known how to measure the energy and velocity of electrons in crystalline materials, but until now the quantum geometry of those…

Physicists show that neutron stars may be covered in axion clouds
Axion cloud around a neutron star. Although some axions escape the star’s gravity, many remain bound to the star and form clouds that surround it for long periods of time. Interaction with the neutron star’s strong magnetic field converts some axions into photons, or light that can eventually be detected by telescopes on Earth. Credit: University of Amsterdam A team…
