Topological Superconductors in Doubly-Coupled Nanowires with Altermagnetism
Hongfa Pan, Haoyang Wang, Wenguang Zhu +1
We theoretically investigate the possibility of engineering topological superconductivity in doubly coupled nanowires integrating proximity-induced superconductivity and altermagne…
Nonlinear Magnetoelectric Edelstein Effect
Jinxiong Jia, Longjun Xiang, Zhenhua Qiao +1
The linear Edelstein effect is a cornerstone phenomenon in spintronics that describes the generation of spin magnetization in response to an applied electric field. Recent theoreti…
Intrinsic gyrotropic magnetic current from Zeeman quantum geometry
Longjun Xiang, Jinxiong Jia, Fuming Xu +2
Quantum geometric tensor (QGT), which is usually obtained by evaluating the quantum distance between Bloch states parametrized by momentum, plays a key role in exploring the exotic…
Equivalence of semiclassical and response theories for second-order nonlinear ac Hall effects
Jinxiong Jia, Longjun Xiang, Zhenhua Qiao +1
It has been known that the semiclassical theory and the response theory can equivalently give the Drude and the intrinsic anomalous Hall conductivities in the linear order of elect…
Fusion Rules of Majorana-Kramer-Pairs in Time-Reversal-Invariant Topological Superconductors
Hongfa Pan, Jinxiong Jia, Zhenhua Qiao
We theoretically investigate the fusion rules of Majorana Kramers pairs in time-reversal-invariant topological superconductors. We find that the fusion of Majorana Kramers pairs is…
Braiding Induced by Finite-Size Effect in One-Dimensional Topological Superconductors
Hongfa Pan, Zhengtian Li, Jinxiong Jia +1
We investigate the transport properties of Majorana zero mode (MZM) and Majorana Kramers pair (MKP) in one-dimensional topological superconductors, respectively. An effective model…
