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…
Quantum phase transition of correlated iron-based superconductivity in LiFeCoAs
Jia-Xin Yin, Songtian S. Zhang, Guangyang Dai +25
The interplay between unconventional Cooper pairing and quantum states associated with atomic scale defects is a frontier of research with many open questions. So far, only a few o…
Insulator-metal transition and quasi-flat-band of Shastry-Sutherland lattice
Huai-Xiang Huang, Jing Chen, Wei Ren +3
Insulator-metal transition is investigated self-consistently on the frustrated Shastry-Sutherland lattice in the framework of Slave-Boson mean-field theory. Due to the presence of…
Anomalous sharp peak in the London penetration depth induced by the nodeless-to-nodal superconducting transition in BaFe(AsP)
Huai-Xiang Huang, Wei Li, Yi Gao +2
The issue of whether the quantum critical point (QCP) is hidden inside unconventional superconductors is a matter of hot debate. Although a prominent experiment on London penetrati…
Spin excitations in nickelate superconductors
Tao Zhou, Yi Gao, Z. D. Wang
We study theoretically spin excitations in the newly discovered nickelate superconductors based on a single-band model and the random phase approximation. The spin excitations are…
Impurity-induced resonant states in topological nodal-line semimetals
Tao Zhou, Wei Chen, Yi Gao +1
Nodal-line semimetals are characterized by a kind of topologically nontrivial bulk-band crossing, giving rise to almost flat surface states. Yet, a direct evidence of the surface s…
