Floquet composite Dirac semimetals
Hong Wu, Jia-Ji Zhu, Jian Li +3
Dirac semimetals can be classified into types I, II, and III based on the topological charge of their Dirac points. If a three-dimensional (3D) system can be sliced into a family o…
Spin-polarized scanning tunneling microscopy measurement scheme for determining the quantum geometric tensor
Shu-Hui Zhang, Jin Yang, Ding-Fu Shao +4
The quantum geometric tensor (QGT) embodies the geometry of the eigenstates of a system's Hamiltonian, and its full characterization across diverse quantum systems is essential. Ho…
RKKY interaction in helical higher-order topological insulators
Sha Jin, Jian Li, Qing-Xu Li +1
We theoretically investigate the RKKY interaction in helical higher-order topological insulators (HOTIs), revealing distinct behaviors mediated by hinge and Dirac-type bulk carrier…
Geometric density of states of electronic structures for local responses: Phase information from the amplitudes of STM measurement
Shu-Hui Zhang, Jin Yang, Ding-Fu Shao +3
Electronic band structures underlie the physical properties of crystalline materials, their geometrical exploration renovates the conventional cognition and brings about novel appl…
The electronic structure of intrinsic magnetic topological insulator MnBi2Te4 quantum wires
Jian Li, Zhu-Cai Yin, Qing-Xv Li +1
The ferromagnetic and antiferromagnetic nanostructure are crucial for fundamental spintronics devices, motivated by its potential application in spintronics, we theoretically inves…
Oblique and asymmetric Klein tunneling across smooth NP junctions or NPN junctions in 8-Pmmn borophene
Zhan Kong, Jian Li, Yi Zhang +2
The tunneling of electrons and holes in quantum structures plays a crucial role in studying the transport properties of materials and the related devices. 8-Pmmn borophene is a new…
Selective generation and amplification of RKKY interactions by P-N interface
Shu-Hui Zhang, Jia-Ji Zhu, Wen Yang +1
We propose a physical mechanism to generate and selectively amplify anisotropic Rudermann-Kittel-Kasuya-Yosida (RKKY) interactions between two local spins. The idea is to combine t…

Electron-phonon bound states in graphene in a perpendicular magnetic field
J. Zhu, S. M. Badalyan, F. Peeters
The spectrum of electron-phonon complexes in a monolayer graphene is investigated in the presence of a perpendicular quantizing magnetic field. Despite the small electron-phonon co…
Electrically-controllable RKKY interaction in semiconductor quantum wires
Jia-Ji Zhu, Kai Chang, Ren-Bao Liu +1
We demonstrate in theory that it is possible to all-electrically manipulate the RKKY interaction in a quasi-one-dimensional electron gas embedded in a semiconductor heterostructure…
