Abstract
Superconductivity has recently been observed in moiré transition-metal dichalcogenide bilayers. Here, we investigate the superconducting state in twisted WSe2 using two complementary theoretical approaches. The first is based on the negative U-Hubbard model and represents a relatively conventional pairing scenario, in which strong electron–electron repulsion does not directly affect the paired state and an isotropic s-wave gap emerges. The second approach employs the t–J–U model, allowing for unconventional gap symmetries and incorporating strong correlation effects via substantial renormalization induced by the Coulomb repulsion. We compare the key properties of the superconducting states obtained within these two frameworks and discuss their implications in light of available experimental observations.
