Researchers present the first definitive experimental fingerprint of a viscous electron fluid in 3D. Thanks to frequent electron-electron collisions, bulk cadmium’s conductivity scales with the square of both temperature and size in a specific window.

The Fermi surface of hexagonal close-packed cadmium consists of a central electron pocket, shown as a blue oval, surrounded by two types of hole pockets, which look like green fins and red triangles.

$Three hexagonal density plots show the electron density (r) of a fractional Chern insulator ground state within a moiré unit cell, The top plot shows a central circular high-density region surrounded by a uniform blue ring inside a hexagon. The bottom left plot has distinct dark-blue density spots arranged in a hexagonal lattice. The bottom right plot shows more concentrated density spots, indicating stronger spatial modulation.$

Researchers observed the mysterious phenomenon of ultraquantum turbulence in a quantum gas far from equilibrium, capturing insights to inform studies of ultracold quantum gases and condensation phenomena.

Scientific figure. Panel (a) shows a simple model of the vortex-tangle decay over time, proceeding from left to right as a series of four cylindrical containers. The containers represent the geometry of the paper’s optical box trap, with purple dots and lines visualizing the quantum turbulence, which gradually dissipates over time. Panel (b) displays a schematic of the paper’s experimental setup. On the left, a small cylinder represents the optical box trap from panel (a). The next step magnifies the cylinder, and shows the taking of a “slice” visualized by an orange rectangle running through the middle. This slice produces the experimental observations, shown on the right as 2D images of the quantum turbulence as well as a numerical simulation. The images are labelled with a color scale bar, ranging from dark blue for the lowest values to white for the highest values.
