Symmetry-Tunable Skyrmions and Merons in Magnetic Nanodisks via Spatially Engineered Anisotropy
X. D. Wang, J. F. Oliveira da Silva, Z. H. Tao +3
We demonstrate that spatially engineered magnetic anisotropy can stabilize skyrmion and meron spin textures in magnetic nanodisks even in the absence of Dzyaloshinskii-Moriya inter…
Reversible and irreversible dynamical topological transitions of magnetic Hopfions
S. Y. Lu, H. M. Dong, D. X. Yu +1
Magnetic Hopfions are three-dimensional (3D) topological solitons characterized by a nonzero Hopf invariant and offer a promising platform for 3D spintronics. While their static st…
Geometric symmetry and size-dependent skyrmion phase transitions in magnetic nanostructures
J. Y. Wang, C. X. Zhao, Y. F. Duan +1
We investigate the interplay of geometric symmetry, size, and external magnetic fields in regulating individual skyrmion states within magnetic nanostructures. By analyzing nanodis…
Ultrasensitive acoustic graphene plasmons in a graphene-transition metal dichalcogenide heterostructure: strong plasmon-phonon coupling and wavelength sensitivity enhanced by a metal screen
Ícaro R. Lavora, Z. H. Tao, H. M. Dongd +3
Acoustic plasmons in graphene exhibit strong confinement induced by a proximate metal surface and hybridize with phonons of transition metal dichalcogenides (TMDs) when these mater…
Exciton states in a circular graphene quantum dot: magnetic field induced intravalley to intervalley transition
L. L. Li, M. Zarenia, W. Xu +2
The magnetic-field dependence of the energy spectrum, wave function, binding energy and oscillator strength of exciton states confined in a circular graphene quantum dot (CGQD) are…
Plasmon and coupled plasmon-phonon modes in graphene in the presence of inter-band excitation channels
H. M. Dong, S. H. Zhang, W. Xu
Plasmon and coupled plasmon-phonon modes in graphene are investigated the-oretically within the diagrammatic self-consistent field theory. It shows that two plasmon modes and four…
