A new quasi 1D compound Ba3TiTe5 was synthesized at high pressure and high temperature, which has been evidenced to be a well-defined 1D conductor. Here, for Ba3TiTe5, in-situ high-pressure techniques were employed to study the emerging physics dependent on interchain hopping, such as the Umklapp scattering effect, SDW/CDW, superconductivity and non-Fermi Liquid behavior. The pressure induced superconductivity was observed. It is suggested that the appearance of superconductivity is associated with the fluctuation due to the suppression of Umklapp gap and the enhancement of Tc is related with the fluctuation of the SDW/CDW.
