WebFor small doping close to the Mott insulator such as p = 0.01, the resis-tivity ﬁrst grows rapidly as T decreases and behaves like an insulator, but then falls and exhibits a broad peak at low temperatures. For larger doping, the resistivity turns metallic in the whole temperature window. WebJun 14, 2024 · The low value of the entropy near half-filling in the doped Mott insulator regime U > U M I T suggests that in this underdoped regime, singlets are more strongly bound by J = 4 t 2 / U than at larger doping. Third, the maximum in the entropy as a function of doping in the underlying normal state is completely obliterated by superconductivity.
