Finite-momentum superconductivity from chiral bands in twisted MoTe
Yinqi Chen, Cheng Xu, Yang Zhang +1
A recent experiment has reported unconventional superconductivity in twisted bilayer MoTe, emerging from a normal state that exhibits a finite anomalous Hall effect -- a signat…

Intrinsic superconducting diode effect and nonreciprocal superconductivity in rhombohedral graphene multilayers
Yinqi Chen, Mathias S. Scheurer, Constantin Schrade
Recent experiments have revealed that superconductivity in rhombohedral tetralayer graphene can emerge from a valley-polarized and, hence, chiral normal state. The interplay of pai…

Verifying the analogy between transversely coupled spin-1/2 systems and inductively-coupled fluxoniums
Wei-Ju Lin, Hyunheung Cho, Yinqi Chen +3
We report a detailed characterization of two inductively coupled superconducting fluxonium qubits for implementing high-fidelity cross-resonance gates. Our circuit stands out becau…
