Third Quantization for Order Parameters (II): Local Field Quantization in Superconducting Quantum Circuits
Miao-Miao Yi, Guo-Jian Qiao, Xin Yue +1
The quantization of superconducting transmission-line resonators is usually introduced phenomenologically by modeling the resonator as an effective LC circuit and imposing canonica…
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…
Third Quantization for Order Parameter (I): BCS-BEC crossover with macroscopically coherent state
Guo-Jian Qiao, Miao-Miao Yi, Xin Yue +1
We revisit the quantization of the order parameter, which we refer to as third quantization, from the perspective of the commutation relation between the phase operator of the orde…
Chirality Breaking of Majorana Edge Modes Induced by Chemical Potential Shifts
Xin Yue, Guo-Jian Qiao
Quantum anomalous Hall insulator-superconductor heterostructures are predicted to host chiral Majorana fermions as edge modes, which is essential for topological quantum computing…
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…
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…
Dressed Majorana fermion in a hybrid nanowire
Guo-Jian Qiao, Xin Yue, C. P. Sun
The low-energy theory of hybrid nanowire systems fails to define Majorana fermion (MF) in the strong tunneling and magnetic field strength. To address this limitation, we propose a…
