Abstract

LaNiO3 is a strange metal, for reasons that are not well understood. Here, Liu et al. report evidence for scattering of charge carriers by antiferromagnetic quantum fluctuations in high-purity epitaxial thin films of LaNiO3, suggesting it is close to an antiferromagnetic quantum critical point.

Abstract

We examine the DC and radio frequency (RF) response of superconducting transmission line resonators comprised of very thin NbTiN films, [Formula: see text] in thickness, in the high-temperature limit, where the photon energy is less than the thermal energy. The resonant frequencies of these superconducting resonators show a significant nonlinear response as a function of RF input power, which can approach a frequency shift of [Formula: see text] in a [Formula: see text] span in the thinnest film. The strong nonlinear response allows these very thin film resonators to serve as high kinetic inductance parametric amplifiers.

3. Two-dimensional superconductivity and anisotropic transport at KTaO

Author

Changjiang, Liu, Xi, Yan, Dafei, Jin, Yang, Ma, Haw-Wen, Hsiao, Yulin, Lin, Terence M, Bretz-Sullivan, Xianjing, Zhou, John, Pearson, Brandon, Fisher, J Samuel, Jiang, Wei, Han, Jian-Min, Zuo, Jianguo, Wen, Dillon D, Fong, Jirong, Sun, Hua, Zhou, and Anand, Bhattacharya

Abstract

The distinctive electronic structure found at interfaces between materials can allow unconventional quantum states to emerge. Here we report on the discovery of superconductivity in electron gases formed at interfaces between (111)-oriented KTaO
