Quantum Metric Induced Critical Current Anomaly in Flat Band Josephson Junctions
Zhong C. F. Li, Yuxuan Deng, Dmitri K. Efetov +1
In well-established theories of Josephson junctions, the superconducting critical current \( I_\mathrm{c} \) increases as the normal state conductance \( \mathcal{G} \) increases.…

Flat Band Josephson Junctions with Quantum Metric
Zhong C. F. Li, Yuxuan Deng, Shuai A. Chen +2
In this work, we consider superconductor/flat band material/superconductor (S/FB/S) Josephson junctions (JJs) where the flat band material possesses isolated flat bands with exactl…
