Experimental signatures of interstitial electron density in transparent dense sodium
Upon compression, the known phase transitions in Na were observed in good agreement with previous investigations15,24,27. The Na samples annealed into quasi-single crystals at the oP8 → tI19 phase transition at 133 GPa, and these crystals…

Sub pico-second pulses in mono-mode optical fibers with Triki-Biswas model
The model proposed by TB is presented as follows
$$\begin{aligned} Q_t+i\textit{a} Q_{\textrm{xx}}+b\left( |Q|^{2 n} Q\right) _x=0. \end{aligned}$$
In order to obtain exact solution to Eq (1), we apply the traveling wave transformation (3), and…

Machine learning climbs the Jacob’s Ladder of optoelectronic properties
We have calculated RPA spectra for all materials in the IPA database24 that have at most 8 atoms in the unit cell, i.e., a total of about 6000 spectra. The structures were originally taken from the Alexandria database of theoretically stable…
