Smallest Swiss cross—made of 20 single atoms

20 bromine atoms positioned on a sodium chloride surface using the tip of an atomic force microscope at room temperature, creating a Swiss cross with the size of 5.6nm. The structure is stable at room temperature and was achieved by exchanging chlorine with bromine atoms. (Credit: Department of Physics, University of Basel)

A Critical Test of Quantum Criticality

a) An example of the classical phase transition in a ferromagnet. Thermal fluctuations causing the random reorientation of the constituent spins grow with temperature. They compete with the tendency of the local magnetic fields to align the spins. As a result, the net magnetization in the ordered state continuously decreases with temperature (orange line) and drops to zero at a critical temperature Tc, surrounded by a narrow critical region (dashed rectangle). (b) A generic example of the quantum phase transition. Quantum fluctuations controlled by the nonthermal parameter g lead to a similar phase transition at a critical value gc, the so called quantum critical point, already at zero temperature, T=0. Their interplay with thermal fluctuations opens up a progressively broader, V-shaped quantum critical region extending much above the zero temperature (dashed lines).

NASA 3D prints a model of light-year-long Eta Carinae nebula

A new shape model of the Homunculus Nebula reveals protrusions, trenches, holes and irregularities in its molecular hydrogen emission. The protrusions appear near a dust skirt seen at the nebula's center in visible light (inset) but not found in this study, so they constitute different structures.
