Deciphering the origin of spin current in spintronic terahertz emitters and its imprint on their electromagnetic radiation via time-dependent density functional theory
Ali Kefayati, Yafei Ren, M. Benjamin Jungfleisch +3
Spin current flowing between femtosecond laser pulse (fsLP)-driven ferromagnetic metal and adjacent normal metal (NM) hosting strong spin-orbit coupling is invariably invoked to ex…
Nonreciprocal phonons in PT-symmetric antiferromagnet
Yafei Ren, Daniyar Saparov, Qian Niu
Phonon nonreciprocity, indicating different transport properties along opposite directions, has been observed in experiments under a magnetic field. We show that nonreciprocal acou…
Engineering second-order topological insulators via coupling two first-order topological insulators
Lizhou Liu, Jiaqi An, Yafei Ren +3
We theoretically investigate the engineering of two-dimensional second-order topological insulators with corner states by coupling two first-order topological insulators. We find t…
Interlayer Coupling Induced Topological Phase Transition to Higher Order
Lizhou Liu, Jiaqi An, Yafei Ren +3
We theoretically find that the second-order topological insulator, i.e., corner states, can be engineered by coupling two copies of two-dimensional topological insul…
Chern Number Tunable Quantum Anomalous Hall Effect in Compensated Antiferromagnets
Wenhao Liang, Jiaqi An, Zeyu Li +3
We propose to realize the quantum anomalous Hall effect (QAHE) in two-dimensional compensated antiferromagnets without net spin magnetization.} We consider antiferromagnetic MnBi$_…
