and anti- phase transitions in a trimerized Su--Schrieffer--Heeger chain with nonreciprocal Rashba spin-orbit coupling
Milad Jangjan, Linhu Li, Longwen Zhou +1
We theoretically investigate a one-dimensional trimerized Su--Schrieffer--Heeger chain with three sublattices per unit cell subjected to a nonreciprocal Rashba spin-orbit coupling.…
Electronic correlations in magnetized helical edge states coupled to s-wave superconductors
Zeinab Bakhshipour, Mir Vahid Hosseini
We theoretically study the role of electron-electron interactions in one-dimensional magnetized helical states coupled to an s-wave superconductor. We consider a partially mixed he…
Spin responses of a disordered helical superconducting edge under Zeeman field
Zeinab Bakhshipour, Mir Vahid Hosseini
We investigate analytically and numerically the effects of disorder on the helical edge of the 2D topological insulator in the presence of the Zeeman field and superconductivity. E…
Promoted current-induced spin polarization in inversion symmetry broken topological insulator thin films
Maryam Heydari, Hanieh Moghaddasi, Mir Vahid Hosseini +1
We theoretically investigate current-induced spin polarization in disordered topological insulator thin films with broken inversion symmetry under an applied in-plane electric fiel…
Quantum Hall Effect and Chern Phases in the 1/5-Depleted Square Lattice
Sara Aghtouman, Godfrey Gumbs, Mir Vahid Hosseini
We investigate the fractional energy spectrum and quantum Hall response of a two-dimensional 1/5-depleted square lattice subjected to a perpendicular magnetic field. Using a tight-…
