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…
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.…
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…
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…
Zero-energy bound states in the high-temperature superconductors at the two-dimensional limit
Chaofei Liu, Cheng Chen, Xiaoqiang Liu +6
Majorana zero modes (MZMs) that obey the non-Abelian statistics have been intensively investigated for potential applications in topological quantum computing. The prevailing signa…
Interface induced Zeeman-protected superconductivity in ultrathin crystalline lead films
Yi Liu, Ziqiao Wang, Xuefeng Zhang +12
Two dimensional (2D) superconducting systems are of great importance to exploring exotic quantum physics. Recent development of fabrication techniques stimulates the studies of hig…
Detection of bosonic mode as a signature of magnetic excitation in one unit cell FeSe on SrTiO3
Chaofei Liu, Ziqiao Wang, Shusen Ye +5
We report an in situ scanning tunneling spectroscopy study of one-unit-cell (1-UC) FeSe film on SrTiO3(001) (STO) substrate. In quasiparticle density of states, bosonic excitation…
High-temperature superconductivity in one-unit-cell FeSe films
Ziqiao Wang, Chaofei Liu, Yi Liu +1
Since the dramatic interface enhancement of superconducting transition temperature (Tc) was reported in one unit-cell FeSe film grown on SrTiO3 substrate (1-UC FeSe/STO) by molecul…
