Engineering nonlinear Hall effect in bilayer graphene/black phosphorus heterostructures
Xing-Guo Ye, Zhen-Tao Zhang, Peng-Fei Zhu +3
Two-dimensional van der Waals materials offer a highly tunable platform for generating emergent quantum phenomena through symmetry breaking. Stacking-induced symmetry breaking at i…
Nonlinear spin and orbital Edelstein effect in WTe2
Xing-Guo Ye, Peng-Fei Zhu, Wen-Zheng Xu +2
In materials with spin-momentum locked spin textures, such as Rashba states and topological surface states, the current-induced shift of the Fermi contour in the k space leads to s…
Facilitating field-free perpendicular magnetization switching with a Berry curvature dipole in a Weyl semimetal
Dong Li, Xing-Yu Liu, Xing-Guo Ye +7
We report the synergy between orbital and spin-orbit torques in WTe2/Fe3GeTe2 heterostructures characterized by a Berry curvature dipole. By applying a current along the a axis in…
Control over Berry Curvature Dipole with Electric Field in WTe2
Xing-Guo Ye, Huiying Liu, Peng-Fei Zhu +5
Berry curvature dipole plays an important role in various nonlinear quantum phenomena. However, the maximum symmetry allowed for nonzero Berry curvature dipole in the transport pla…
Orbital polarization and third-order anomalous Hall effect in WTe2
Xing-Guo Ye, Peng-Fei Zhu, Wen-Zheng Xu +3
The anomalous Hall effect (AHE) has been extended into the nonlinear regime, where the Hall voltage shows higher-order response to the applied current. Nevertheless, the microscopi…
Proximity-induced superconducting gap in the intrinsic magnetic topological insulator MnBi2Te4
Wen-Zheng Xu, Chun-Guang Chu, Zhen-Cun Pan +7
We report magnetotransport measurements in the NbN/ magnetic topological insulator MnBi2Te4 (MBT)/ NbN junction at low temperature. At 10 mK, the nonlinear current-voltage characte…
Strain-dependent resistance and giant gauge factor in monolayer WSe2
Mao-Sen Qin, Xing-Guo Ye, Peng-Fei Zhu +4
We report the strong dependence of resistance on uniaxial strain in monolayer WSe2 at various temperatures, where the gauge factor can reach as large as 2400. The observation of st…
Design of an experiment to study the motion of nano-liquid helium droplets
Pu Huang, Penghao Zhu
One of the most important task in physics today is to merge quantum mechanics and general relativity into one framework. And the main barrier in this task is that we lack quantum g…
