Unveiling Rare Physics: Charge Waves in Superconductors
Researchers have observed unusual waves of charge within a crystal of uranium ditelluride (UTe2), a superconductor. Using advanced imaging tools, they discovered the presence of charge density waves that are intertwined with the material's superconductivity. The waves are believed to be spawned by a wave made up of Cooper pairs, providing insights into the types of order that occur in UTe2. This is the first time evidence of interwoven parent-daughter waves has been seen in a superconductor with triplet pairing, suggesting the existence of a fundamentally new phase due to strong electron interactions.
