Interplay between Quantum Metric and Hybridized Collective Mode in Flat-Band Superfluids
Yi Liu, Mingyan Wang, Penghui Hu +1
We investigate collective excitations in flat-band superfluids by incorporating the coupled dynamics of pairing (phase and amplitude) and density fluctuations. We demonstrate that…

Superconductivity Mediated Long Range Magnetic Coupling
Ming Yan Wang, Yi Liu, Yao Lu
We investigate a Rashba superconductor thin film coupled to overlaying ferromagnetic insulators (FIs). We show that the ferromagnetic insulators generate circular super-currents, e…
