National Tsing Hua University Spots Quantum Critical Point

National Tsing Hua University researchers, including Dean Chung-Yu Mou, have provided the first definitive evidence of a quantum critical point (QCP) in high-temperature cuprate superconductors, addressing a 40 year old mystery. The team clarified how the material’s quantum states change on either side of this critical point, offering a clearer picture of the complicated phase diagram of these superconductors.
