Exploring Potential Charge Density Waves in the One-dimensional Superconductor Ta4Pd3Te16

The coexistence of superconductivity with competing ground states continues to be a useful field for exploring novel quantum behavior. The monoclinic crystal Ta4Pd3Te16 is a one-dimensional superconductor with critical temperature 4.2 K. Previous Scanning Tunneling Microscopy (STM) measurements suggest a Charge Density Wave (CDW) existing at and below 4 K. Additionally, an anomaly in the resistivity occurs around 18 K, suggesting a thermodynamic phase transition. Further studies are required to understand the relationship between this thermodynamic transition, the charge density waves, and superconductivity. We discuss quantum oscillation and synchrotron X-ray studies of charge density waves in this novel superconductor.
