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…

Exact bound of power-efficiency trade-off in finite-time thermodynamic cycles
R. X. Zhai, Xin Yue, C. P. Sun
Power and efficiency are fundamental criteria for evaluating the performance of thermodynamic cycles. However, it is generally impossible to maximize both simultaneously. In partic…

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…
