"Exploring the Complex Relationship Between Charge Density Waves and Superconductivity in Pressurized CuTe"

Researchers have discovered a second charge density wave (CDW) order in the quasi-one-dimensional CDW material CuTe under high pressure. They found that superconductivity can be induced and has complex relationships with the native and emergent CDW orders. The transition from the original CDW order (CDW1) to the new CDW order (CDW2) was accompanied by the appearance of a pressure-induced dome-like superconducting phase diagram. This study highlights CuTe as an ideal platform to study the interplay between superconductivity and multiple CDWs.

Atomic distortions reveal potential superconductor's charge density wave.

Scientists at Brookhaven National Laboratory have used a spectroscopic imaging scanning tunneling microscope to study the relationship between the lattice structure and electronic structure of a copper-oxide superconductor. They found that the disappearance of vibrational energy from the atoms that make up the material's crystal lattice was linked to the emergence of a "charge density wave" - a modular distribution of charge density in the material. The appearance of this pattern distorts the normal vibrations of the atoms and shifts their positions along the direction of the "rungs."
