Sensitive dependence of Poor Man's Majorana modes on the length of the superconductor
Zhi-Lei Zhang, Xin Yue, Guo-Jian Qiao +1
In a hybrid system where two quantum dots (QDs) are coupled to a conventional -wave superconductor, Poor Man's Majorana modes (PMMs) have been proposed. Existing theories often…
Size optimization for observeing Majorana fermions
Guo-Jian Qiao, Zhi-Lei Zhang, Xin Yue +1
Majorana fermions (zero modes) are predicted to emerge in nanowire-superconductor heterostructures. This theoretical prediction typically relies on an oversimplified model, where b…
Poor Man's Majoranon in Two Quantum Dots Dressed by Superconducting Quasi-Excitations
Zhi-Lei Zhang, Guo-Jian Qiao, C. P. Sun
In a hybrid system consisting of two quantum dots (QDs) coupled to a superconductor (SC), zero-bias peaks in the differential conductance spectrum have been reported as potential s…
Finite Thickness Effects on Metallization Vs. Chiral Majorana Fermions
Xin Yue, Guo-Jian Qiao, C. P. Sun
The search for chiral Majorana fermions in quantum anomalous Hall insulator/\textit{s}-wave superconductor heterostructures has attracted intense interest, yet remains controversia…
