Ultra-high temperature Soret effect in a silicate melt: SiO2 migration to cold side
Yuma Nishida, Masahiro Shimizu, Tatsuya Okuno +3
The Soret effect, temperature gradient driven diffusion, in silicate melts has been investigated intensively in the earth sciences from the 1980s. The SiO2 component is generally c…

Diamond photonics platform enabled by femtosecond laser writing
Belen Sotillo, Vibhav Bharadwaj, J. P. Hadden +14
We demonstrate the first buried optical waveguides in diamond using focused femtosecond laser pulses. The properties of nitrogen vacancy centers are preserved in the waveguides, ma…
