Charge density wave and pressure-induced reentrant superconductivity in ZrTe$_{3}$

We have investigated the pressure effects near the phase boundary between the CDW and the pressure-induced reentrant-superconductivity (r-SC) in ZrTe$_{3}$, where, simultaneously with the collapse of the CDW state, appears again the SC. Fluctuations of the CDW and the SC have become stronger as both transitions approach to the phase boundary. We discuss the possible exsitence of a novel state between the CDW and the r-SC phases
