    We report the interplay between charge-density-wave (CDW) and superconductivity of 1TT-Fex_{x}Ta1−x_{1-x}S2_{2} (0≤x≤0.050\leq x \leq 0.05) single crystals. The CDW order is gradually suppressed by Fe-doping, accompanied by the disappearance of pseudogap/Mott-gap as shown by the density functional theory (DFT) calculations. The superconducting state develops at low temperatures within the CDW state for the samples with the moderate doping levels. The superconductivity strongly depends on xx within a narrow range, and the maximum superconducting transition temperature is 2.8 K as x=0.02x=0.02. We propose that the induced superconductivity and CDW phases are separated in real space. For high doping level (x>0.04x>0.04), the Anderson localization (AL) state appears, resulting in a large increase of resistivity. We present a complete electronic phase diagram of 1TT-Fex_{x}Ta1−x_{1-x}S2_{2} system that shows a dome-like Tc(x)T_{c}(x)

    We study the bosonic super Liouville system which is a statistical transmutation of super Liouville system. Lax pair for the bosonic super Liouville system is constructed using prolongation method, ensuring the Lax integrability, and the solution to the equations of motion is also considered via Leznov-Saveliev analysis.Comment: LaTeX, no figures, 11 page
