A Connectivity-Order Law and Conditional Minimal-Mechanism Identification in Many-Body Geometric Phases
Kuo Hai, Junhao Huang, Qiong Chen +1
The value of a multiqubit geometric phase at a single operating point does not reveal whether it was generated directly or through a connected sequence of lower-body interactions.…

Stability of spin dynamics for a spin-orbit coupled boson in a driven non-Hermitian double well
Zhida Luo, Yurui Yang, Jiaxi Cui +5
We study the stability of spin dynamics for a spin-orbit (SO) coupled boson held in a driven non-Hermitian double-well potential. Under high-frequency approximation, we analyticall…

Coherently controlling robust spin-orbit qubits of electrons in nanowire quantum dots
Kuo Hai, Xuefang Deng, Qiong Chen +1
We consider an electron confined in a gated nanowire quantum dot (NQD) with arbitrarily strong spin-orbit coupling (SOC) and weak static magnetic field, and treat the latter as a p…
