The Remarkable Underlying Ground States of Cuprate Superconductors
The Remarkable Underlying Ground States of Cuprate Superconductors
Cuprates exhibit exceptionally strong superconductivity. To understand why, it is essential to elucidate the nature of the electronic interactions that cause pairing. Superconductivity occurs on the backdrop of several underlying electronic phases, including a doped Mott insulator at low doping, a strange metal at high doping, and an enigmatic pseudogap …
