Edge States and Quantum Hall Effect in Graphene under a Modulated Magnetic Field
Lei Xu, Jin An, Chang-De Gong
Graphene properties can be manipulated by a periodic potential. Based on the tight-binding model, we study graphene under a one-dimensional (1D) modulated magnetic field which cont…
Induced chiral Dirac fermions in graphene by a periodically modulated magnetic field
Lei Xu, Jin An, Chang-De Gong
The effect of a modulated magnetic field on the electronic structure of neutral graphene is examined in this paper. It is found that application of a small staggered modulated magn…
Construction of Chiral Metamaterial with U-Shaped Resonator Assembly
Xiang Xiong, Wei-Hua Sun, Yong-Jun Bao +7
Chiral structure can be applied to construct metamaterial with negative refractive index (NRI). In an assembly of double-layered metallic U-shaped resonators with two resonant freq…
Long-Wavelength Optical Properties of a Plasmonic Crystal
Cheng-ping Huang, Xiao-gang Yin, Qian-jin Wang +2
The long-wavelength optical properties of a plasmonic crystal composed of gold nanorod particles have been studied. Because of the strong coupling between the incident light and vi…
Quantum interference induced by multiple Landau-Zener transitions in a strongly driven rf-SQUID qubit
Yiwen Wang, Shanhua Cong, Xueda Wen +7
We irradiated an rf-SQUID qubit with large-amplitude and high frequency electromagnetic field. Population transitions between macroscopic distinctive quantum states due to Landau-Z…
The Spontaneous Generation of Magnetic Moment of Beryllium Dimer on Graphene
Xiang He, Zhao-Xu Chen, Zhaosheng Li +1
Graphene has various potential applications in electronics and scientists are seeking to introduce magnetic properties on graphene. Here we report our theoretical findings that a l…
