Mean-field study of the Bose-Hubbard model in Penrose lattice
Rasoul Ghadimi, Takanori Sugimoto, Takami Tohyama
We examine the Bose-Hubbard model in the Penrose lattice based on inhomogeneous mean-field theory. Since averaged coordination number in the Penrose lattice is four, mean-field pha…
Disorder and Zeeman coupling induced gap-filling states in the nodeless chiral superconducting Bi/Ni bilayer system
Rasoul Ghadimi, Mehdi Kargarian, S. Akbar Jafari
Motivated by the recently discovered time-reversal symmetry-breaking superconductivity in epitaxial Bi/Ni bilayer system with transition temperature K and the obser…
Competing superconducting phases in interacting two-dimensional electron gas with strong Rashba spin-orbit coupling
Rasoul Ghadimi, Mehdi Kargarian, S. Akbar Jafari
In this work we study interacting electrons on square lattice in the presence of strong Rashba spin-orbit interaction. The spin-orbit term forces the time-reversal electron states…
Topological phase diagram of the disordered 2XY model in presence of generalized Dzyaloshinskii-Moriya Interaction
Alireza Habibi, Rasoul Ghadimi, S. A. Jafari +1
Topological index of a system specifies gross features of the system. However, in situations such as strong disorder where by level repulsion mechanism the spectral gap is closed,…
Majorana Zero-Energy Mode and Fractal Structure in Fibonacci-Kitaev Chain
Rasoul Ghadimi, Takanori Sugimoto, Takami Tohyama
We theoretically study a Kitaev chain with a quasiperiodic potential, where the quasiperiodicity is introduced by a Fibonacci sequence. Based on an analysis of the Majorana zero-en…
