Researchers have proposed a new protocol to induce superconductivity in two-dimensional moiré heterostructures, without relying on traditional attractive interactions. This method, termed driven-dissipative preparation, aims to establish superconductivity as a stationary state. The key lies in a bilayer moiré platform where the layer degree of freedom acts as a pseudospin, allowing the pseudospin structure required for pairing to be implemented through optically induced spatial operations.

The scheme requires local dissipation, which naturally arises from weakly dispersive bosonic modes present in the heterostructure. In contrast, in the opposite regime of collective dissipation, the same platform exhibits an early-time superradiant burst. This approach represents an alternative to conventional superconductivity mechanisms, which generally rely on enhancing attractive interactions between electrons.

The results of this research establish driven-dissipative moiré heterostructures as a promising platform for preparing superconductivity. Furthermore, the study reveals an unexpected connection between steady-state pairing and transient superradiance. This finding opens new avenues for exploring quantum phenomena and developing superconducting materials with properties controlled by light and dissipation.
