Response tensor for the superconducting (Josephson) diode effect
Qiong Qin, Jie Wu, Congjun Wu
We propose a response tensor to characterize the non-reciprocal critical current response of the superconducting (Josephson) diode effect. It describes the coupli…
Emergent superconducting stripes in two-orbital superconductors
Qiong Qin, Yi-feng Yang
Motivated by recent experiments in KTaO/EuO interface, we propose an intrinsic mechanism where superconducting stripes emerge naturally without involving disorder, charge inhom…
Chiral finite-momentum superconductivity in the tetralayer graphene
Qiong Qin, Congjun Wu
Motivated by the recent experimental discovery of superconductivity in rhombohedral tetralayer graphene, we investigate the pairing mechanism arising from the density-density inter…
Frustrated superconductivity and intrinsic reduction of in trilayer nickelate
Qiong Qin, Jiangfan Wang, Yi-feng Yang
Identifying the key factors controlling the magnitude of is of critical importance in the pursuit of high-temperature superconductivity. In cuprates, reaches its maxima…
