Temperature dependence of the electronic structure of Ca3Cu2O4Cl2 Mott insulator
Li Haiwei, Ye Shusen, Zhao Jianfa +2
We use scanning tunneling microscopy to study the temperature evolution of electronic structure in Ca3Cu2O4Cl2 parent Mott insulator of cuprates. We find that the upper Hubbard ban…
Long-Time Magnetic Relaxation in Antiferromagnetic Topological Material EuCdAs
Yang Wang, Cong Li, Yong Li +12
Magnetic topological materials have attracted much attention due to the correlation between topology and magnetism. Recent studies suggest that EuCdAs is an antiferromagnet…
Superconductivity above 200 K Observed in Superhydrides of Calcium
Z. Li, X. He, C. L. Zhang +20
Searching for superconductivity with Tc near room temperature is of great interest both for fundamental science & many potential applications. Here we report the experimental disco…
Momentum-Resolved Visualization of Electronic Evolution in Doping a Mott Insulator
Cheng Hu, Jianfa Zhao, Qiang Gao +13
High temperature superconductivity in cuprates arises from doping a parent Mott insulator by electrons or holes. A central issue is how the Mott gap evolves and the low-energy stat…
Imaging the atomic-scale electronic states induced by a pair of hole dopants in Ca2CuO2Cl2 Mott insulator
Haiwei Li, Shusen Ye, Jianfa Zhao +2
We use scanning tunneling microscopy to visualize the atomic-scale electronic states induced by a pair of hole dopants in Ca2CuO2Cl2 parent Mott insulator of cuprates. We find that…
Crystal structure and properties of iron-based spin-chain compound Ba9Fe3Se15
Jun Zhang, Alexander C. Komarek, Meiling Jin +18
We report the synthesis of a new quasi one-dimensional (1D) iron selenide. Ba9Fe3Se15 was synthesized at high temperature and high pressure of 5.5 GPa and systematically studied vi…
