  • What does "fired up"

    Fired up means something like impassioned or in the case of a steam engine fired up with fossil fuel..


    the new energy minister has been out in the cold since 2013 since his party lost the election


    Chris Bowen is probably acting up a little bit in front of the cameras..now that his party is back from the wilderness

    He says there is no silver bullet.... but perhaps palladium together with silver samarium and other rare earths plus deuterium may be more eonomical than silicon solar

    Neighboring Atom Collisions in Solid-State High Harmonic Generation

    by R Zuo · 2021 · Cited by 3


    Abstract

    High harmonic generation (HHG) from solids shows great application prospects in compact short-wavelength light sources and as a tool for imaging the dynamics in crystals with subnanometer spatial and attosecond temporal resolution. However, the underlying collision dynamics behind solid HHG is still intensively debated and no direct mapping relationship between the collision dynamics with band structure has been built. Here, we show that the electron and its associated hole can be elastically scattered by neighboring atoms when their wavelength approaches the atomic size. We reveal that the elastic scattering of electron/hole from neighboring atoms can dramatically influence the electron recombination with its left-behind hole, which turns out to be the fundamental reason for the anisotropic interband HHG observed recently in bulk crystals. Our findings link the electron/hole backward scattering with Van Hove singularities and forward scattering with critical lines in the band structure and thus build a clear mapping between the band structure and the harmonic spectrum. Our work provides a unifying picture for several seemingly unrelated experimental observations and theoretical predictions, including the anisotropic harmonic emission in MgO, the atomic-like recollision mechanism of solid HHG, and the delocalization of HHG in ZnO. This strongly improved understanding will pave the way for controlling the solid-state HHG and visualizing the structure-dependent electron dynamics in solids.

  • I posted this on The Playground. A few friends said it is relevant to advanced CMNS solid state fusion development and may be worthy of its own thread 🧵


    How might this paper relate to traditional fusion energy development is the question in our minds. Not being physicists, its posted here for review and initial reactions and comments. If it is relevant to CMNS Solid State Atomic and Fusion energy development...

    A dedicated thread for in depth discussion will be started.

    Abstract

    The electromagnetic field enhancement factors by gap plasmons between two spherical metal particles are calculated for hydrogen-absorbing transition metals Pd, Ti, and Ni, and reference noble metals Au, Ag, and Cu, in air, H2, or vacuum, and H2O. The dependence of the field enhancement factors on the metal species, the field wavelength, the electric field polarization, the separation of the two metal particles, and the observing location is systematically investigated. Field enhancement is observed significantly large in the gap of two metal particles and sensitive to the particle separation, but insensitive to the position in the gap, indicating a geometric flexibility for applications. The spectral peak field enhancement factors for Pd, Ti, and Ni do not compete with those for Au, Ag, and Cu, but do in the microwave regime. For the electric field parallel to the bipartite alignment, the field enhancement factors in the gap for Pd, Ti, and Ni are observed as large as several hundred and ten thousand for the separation-to-radius ratios of 0.1 and 0.01, respectively, for a wide wavelength region spanning from the visible to the infrared.


    The large field enhancements in the nanogaps of hydrogen-absorbing transition metals observed in this study can potentially be utilized for various energy applications, such as hydrogen storage, sensing, and nuclear fusion.


    In practical metallic material systems, it is important to account for such a gap-plasmon effect because nanoscale gaps commonly exist, for instance, on rough metal surfaces and in metal particle aggregates.

    Dr. Michael Clarage of the Safire project takes us on a walk through the very edges of science to see if we can figure out what will change about the models that we hold so dear today. What is the Safire project working on, and how will it change our understanding of the stars, the galaxies, and everything else? What if we're living in a conscious universe? How would that force us to see the world differently? What's the role of light in biology? It's a wild ride, so buckle up!!
