We explored electrically tunable exciton-mediated superconductivity in bilayer semiconductors. Gating conditions were identified to achieve exciton density wave order, leading to superconductivity via Goldstone modes.
Area of Science:
- Condensed matter physics
- Materials science
Background:
- Synthetic platforms offer advanced control over strongly correlated phases.
- Bilayer semiconductors are promising for novel quantum phenomena.
Purpose of the Study:
- Investigate electrically tunable exciton-mediated superconductivity.
- Identify conditions for exciton density wave order in charge-imbalanced bilayer semiconductors.
Main Methods:
- Self-consistent Hartree-Fock approximation.
- Analysis of exciton-fermion coupling.
- Investigated Goldstone mode mediation of interactions.
Main Results:
- Identified gating conditions for exciton density wave order.
- Demonstrated Goldstone modes mediate attractive interactions, inducing superconductivity.
- Showcased potential for interlayer pair-density wave superconductors near density wave order.
Conclusions:
- Exciton-mediated superconductivity is achievable and electrically tunable in bilayer semiconductors.
- Excitonic fluctuations play a crucial role in mediating superconductivity.
- The study proposes experimental signatures for observed phenomena.
