Anomalous linear magnetoresistance in high quality crystalline lead thin films
Yi Liu, Yue Tang, Ziqiao Wang +3
Intriguing novel phenomena in lead films inspire new understanding of quantum physics, such as quantum size effect and quantum phase transitions etc. The improvement of the sample…
Type-II Ising superconductivity and anomalous metallic state in macro-size ambient-stable ultrathin crystalline films
Yi Liu, Yong Xu, Jian Sun +13
Recent emergence of two-dimensional (2D) crystalline superconductors has provided a promising platform to investigate novel quantum physics and potential applications. To reveal es…
Quantum coherence across bosonic superconductor-anomalous metal-insulator transitions
Chao Yang, Yi Liu, Yang Wang +15
After decades of explorations, suffering from low critical temperature and subtle nature, whether a metallic ground state exists in a two-dimensional system beyond Anderson localiz…
Anomalous quantum Griffiths singularity in ultrathin crystalline lead films
Yi Liu, Ziqiao Wang, Pujia Shan +9
We study the magnetic field induced superconductor-metal transition (SMT) in ultrathin crystalline Pb films. By performing ultralow temperature transport measurement, the divergent…
