Extended Hubbard model on fractals: d-Wave superconductivity and competing pairing channels
Robert Canyellas, Mikhail I. Katsnelson, Andrey Bagrov
Fractal structures such as the Sierpiński 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…

Topological edge and corner states in Bi fractals on InSb
R. Canyellas, Chen Liu, R. Arouca +10
Topological materials hosting metallic edges characterized by integer quantized conductivity in an insulating bulk have revolutionized our understanding of transport in matter. The…
