A type of atomic vibration
never before seen in ordinary solid materials has been observed in uranium.
The team used Raman spectroscopy to measure the atomic vibrations
throughout a microscopic fossil of a protist, at a sub-micron resolution, and then analyzed the resulting spectra using their new analytic technique.
Objective: Phonons (collective atomic vibrations
in solids) are more effective in transporting heat than photons.
The author explores crystal structure and crystal diffraction, crystal binding and elastic constants, atomic vibrations
and lattice specific heat, free electrons theory and simple metals, and many other related subjects.
When you touch an object and it feels 'hot' you are literally sensing the 'buzzing' of the atomic vibrations
But when it does, it's less likely to set another electron free than it is to create atomic vibrations
that squander the electron's excess energy on heat.
The laser, working together with an external light source, makes use of the natural I atomic vibrations
in silicon to amplify the pump-light as it passes through the chip.
Conventional optical lattice clocks cannot eliminate influences of electromagnetic waves released from grid walls surrounding the atoms, which disrupts the cycles of the atomic vibrations
For instance, "the comparison of protein structures at ultra-cold versus room temperature allows the details of atomic vibrations
to be separated from structural disorders," says Helliwell.
Others believed, as did physicist Rudolf Peierls, that atomic vibrations
and distortions trumped all.
