Marginal-Fermi-Liquid-like Behavior without Pseudogap in Infinite-Layer Nickelates

Yu Fan, Zhitong An, Xiang Ding +10

Pseudogap formation, strange-metal behavior and unconventional superconductivity are closely intertwined in hole-doped cuprates, yet their relationship remains unresolved. Infinite…

A Disconnected Superconducting Regime at the Parent Limit of Infinite-Layer Nickelates

Chihao Li, Yutong Chen, Yaolong Bian +11

Infinite-layer nickelates have been widely viewed as cuprate analogs in which superconductivity emerges and forms a superconducting dome centered around 10-20% cation substitution.…

Thermoelectricity evidence for quantum criticality in clean infinite-layer nickelate films

Xu Zhang, Chihao Li, Mingwei Yang +8

We investigate the Seebeck coefficient ( $S$ ) in infinite-layer nickelate films with different disorder levels. The disordered NdNiO $_{2}$ film exhibits a flat $S / T$ curve, whereas…

Observation of Electride-like $s$ States Coexisting with Correlated $d$ Electrons in NdNiO $_{2}$

Chihao Li, Yutong Chen, Xiang Ding +13

Despite exhibiting a similar $d_{x^{2} - y^{2}}$ band character to cuprates, infinite-layer nickelates host additional electron pockets that distinguish them from single-band cuprates. T…

High Temperature Superconductivity Dominated by Inner Underdoped CuO $_{2}$ Planes in Quadruple-Layer Cuprate (Cu,C)Ba $_{2}$ Ca $_{3}$ Cu $_{4}$ O $_{11 + δ}$

Xingtian Sun, Suppanut Sangphet, Nan Guo +9

The superconducting transition temperature ( $T_{c}$ ) of trilayer or quadruple-layer cuprates typically surpasses that of single-layer or bilayer systems. This observation…
