Extended Hubbard model on fractals: d-Wave superconductivity and competing pairing channels
Robert Canyellas, Mikhail I. Katsnelson, Andrey Bagrov
Fractal structures such as the SierpiÅski gasket have been predicted to enhance the critical temperature of s-wave superconductivity compared to regular crystals while maintaining…

Strong enhancement of superconductivity on finitely ramified fractal lattices
Askar A. Iliasov, Robert Canyellas, Mikhail I. Katsnelson +1
Using the Sierpinski gasket (triangle) and carpet (square) lattices as examples, we theoretically study the properties of fractal superconductors. For that, we focus on the phenome…
