Majorana Fermions in spin up and down electronic complexes in spin-orbit coupled array of semiconductor quantum dots in proximity to -type superconductor and in magnetic field
Mijanur Islam, Mahan Mohseni, Ibsal Assi +2
Semiconductor-s-type superconductor nanowires host spinful fermions and cannot be reduced to a single spinless Kitaev chain hosting single Majorana zero mode. Instead, such systems…
Conductance properties of an - Corbino disk
Mijanur Islam, Saurabh Basu
In this work, we investigate an - lattice in the form of a Corbino disk, characterized by inner and outer radii and , threaded by a tunable magnetic flux. Throu…
Holstein polaron in a pseudospin- quantum spin Hall system: first and second order topological phase transitions
Kuntal Bhattacharyya, Srijata Lahiri, Mijanur Islam +1
We theoretically propose the occurrence of a quantum spin Hall (QSH) and a second order topological phase transition (TPT) driven by electron-phonon (e-p) coupling in a pseudospin-…
Electron-phonon coupling induced topological phase transition in an - Haldane-Holstein model
Mijanur Islam, Kuntal Bhattacharyya, Saurabh Basu
We present impelling evidence of topological phase transitions induced by electron-phonon (e-ph) coupling in an - Haldane-Holstein model that presents smooth tunability be…
