Monte Carlo simulations identify cI16 as mechanically metastable for classical hard spheres
Monte Carlo results confirm the body-centered cubic structure as an unstable phase for hard spheres and identify a mechanically stable amorphous crystalline structure.
Advances in vibrational spectroscopy provide new ways for characterizing semiconductor impurities
Improvements in computing push the boundaries of vibrational spectroscopy, allowing for observation of new electronic properties of semiconductors with light-mass element impurities.
Whiskered foam surface traps secondary electrons in simulations
Analysis of simulations describe how fuzz-covered foam surfaces can reduce secondary electron emission that can be problematic in some systems, such as particle accelerators and spacecraft propulsion.
A new interpretation brings better plasma spectroscopy measurements
Applying a Lagrangian model to laser-induced fluorescence gives quicker and more accurate interpretation of plasma measurements, including ion temperature.
Phononic frequency comb demonstrated by nonlinear trimodal coupling
A driven micromachined device exhibits three-mode four-wave mixing and points to realizable multimode phononic frequency combs.
Developing a quantum theory of multiscale coarse-graining
Theoretical chemists have come up with a theory of coarse-graining for the quantum mechanical regime to simplify complex molecular simulations.
