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…
