Ab initiomany-body Green's function calculations of optical properties of LiF at high pressures

“…We see that our calculated n increases almost linearly with ρ, but with a slight downward curvature. This trend is in excellent agreement with the results of the available experimental data 5,[8][9][10][11] , and par-ticularly so for the recent results obtained by Rigg et al 11 , reproduced here as the green and magenta points in fig. 5a.…”

“…5 shows the calculated real part of the index of refraction, n. We consider both n(ω = 0) and n(λ = 532nm) ( ω = 2.33 eV), as in recent experiments 8,11 where n was additionally determined in the infrared (λ = 1550 nm). We see that our calculated n increases almost linearly with ρ, but with a slight downward curvature.…”

“…In particular, Jensen et al showed that n for two different laser wavelengths (532 nm and 1550 nm) is linearly increasing with density 8 . This was later modified by Rigg et al 11 , who performed more measurements along the shock Hugoniot and determined quadratic corrections to this linear behavior.…”

“…Several of these have focused specifically on its high-pressure optical properties, and have collectively determined the real part of the index of refraction, n, for densities up to just over 4 g/cm 3 (∼ 60% increase in density above ambient) 5,[8][9][10][11] .…”

“…Because of these applications (in addition to its fundamental interest as a prototypical wide-gap material) LiF itself has been the subject of a number of dynamic high-pressure experimental investigations [5][6][7][8][9][10][11] . Several of these have focused specifically on its high-pressure optical properties, and have collectively determined the real part of the index of refraction, n, for densities up to just over 4 g/cm 3 (∼ 60% increase in density above ambient) 5,[8][9][10][11] .…”
