Local Raman Spectroscopy of Chiral Majorana Edge Modes in Kitaev Spin Liquids and Topological Superconductors
James Jun He, Naoto Nagaosa
The Raman scattering with local optical excitation from the Majorana edge modes of Kitaev spin liquids and topological superconductors is studied theoretically. Although the effect…
Optical Responses of Chiral Majorana Edge States in Two-Dimensional Topological Superconductors
James Jun He, Yukio Tanaka, Naoto Nagaosa
Majorana fermions exist on the boundaries of two-dimensional topological superconductors (TSCs) as charge-neutral quasi-particles. The neutrality makes the detection of such states…
Superconductivity beyond Pauli's limit in bulk NbS2: Evidence for the Fulde-Ferrell-Larkin-Ovchinnikov state
Chang-woo Cho, Jian Lyu, Cheuk Yin Ng +4
We present magnetic torque, specific heat and thermal expansion measurements combined with a piezo rotary positioner of the bulk transition metal dichalcogenide (TMD) superconducto…
Non-Hermitian topological Mott insulators in one-dimensional fermionic superlattices
Tao Liu, James Jun He, Tsuneya Yoshida +2
We study interaction-induced Mott insulators, and their topological properties in a 1D non-Hermitian strongly-correlated spinful fermionic superlattice system with either nonrecipr…
Spin supercurrent in two-dimensional superconductors with Rashba spin-orbit interaction
James Jun He, Kanta Hiroki, Keita Hamamoto +1
Spin current is a central theme in spintronics, and its generation is a keen issue. The spin-polarized current injection from the ferromagnet, spin battery, and spin Hall effect ha…
Emergent Josephson current of chiral topological superconductor in quantum anomalous Hall insulator/superconductor heterostructures
Chui-Zhen Chen, James Jun He, Dong-Hui Xu +1
Recently, a quantum anomalous Hall insulator (QAHI)/superconductor heterostructure has been realized and shows half-quantized conductance plateaus in two-terminal conductance measu…
