This study demonstrates through simulations and *ab initio* calculations that stacking two-dimensional van der Waals materials can induce a robust, high-temperature inter-layer s-wave superconductivity driven by a strong-coupling Kohn-Luttinger mechanism, where pairing attraction scales linearly with inter-layer repulsion rather than quadratically.
This paper develops a self-consistent microscopic thermodynamic framework that unifies fermionic quasiparticles, Coulomb-regularized phase fluctuations, and BKT vortices to explain how disorder and carrier density drive the separation between the superconducting gap and transition temperature in 2D systems, successfully reproducing experimental results for bilayer MoS and disordered InO films.
Using large-scale density matrix renormalization group simulations of the bosonic -- model, this study reveals six distinct quantum phases—including pair density waves and phase-separated ferromagnetic domains—arising from the competition between doped holes and antiferromagnetic order, while proposing a concrete experimental realization in Rydberg tweezer arrays to explore these intertwined orders relevant to high- superconductivity.
