Dynamical Coulomb Blockade as a Signature of the Sign-Reversing Cooper Pairing Potential
Chaofei Liu, Pedro Portugal, Yi Gao +8
Coulomb blockade occurs for electrons tunneling into nanoislands because of the quantization of charge. Here, using spectroscopy measurements of nonmagnetic islands grown on a high…
Determination of the Zak phase of one-dimensional photonic systems via far-field diffraction
Chao Liu, Haoran Wang, H. C. Ong
Bloch waves in 1D periodic systems carry Zak phase, which plays a key role in determining the band topology. In general, for systems that possess inversion symmetry, the Zak phase…
Orbital-Selective High-Temperature Cooper Pairing Developed in the Two-Dimensional Limit
Chaofei Liu, Andreas Kreisel, Shan Zhong +4
The orbital multiplicity in multiband superconductors yields orbital differentiation in normal-state properties, and can lead to orbital-selective spin-fluctuation Cooper pairing.…
Equally Spaced Quantum States in van der Waals Epitaxy-Grown Nanoislands
Chaofei Liu, Chunxiang Zhao, Shan Zhong +4
Pursuing the confinement of linearly dispersive relativistic fermions is of interest in both fundamental physics and potential applications. Here, we report strong STM evidence for…
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…
Heterostructural one-unit-cell FeSe/SrTiO3: from high-temperature superconductivity to topological states
Chaofei Liu, Jian Wang
High temperature superconductivity in one unit cell (1 UC) FeSe on SrTiO3 heterostructure has become a research frontier in condensed matter physics and material science. The super…
