论文摘要
我们研究了磁场对石墨烯中狄拉克费物的影响，但会受到标量势振荡的时间。使用Floquet理论和共振近似，我们表明能量光谱还表现出额外的子带，该子带是由于除量化的Landau水平外的振荡潜力而产生的。发现可以在$ x $和$ y $的指导中产生当前密度，这很大程度上取决于磁场和潜力。我们的数值分析表明，能量光谱具有对称性，并且电流密度在各种条件下具有不同幅度的振荡。
We study the effect of a magnetic field on Dirac fermions in graphene subject to a scalar potential oscillating in time. Using the Floquet theory and resonance approximation, we show that the energy spectrum exhibits extra subbands resulted from the oscillating potential in addition to quantized Landau levels. It is found that a current density can be generated in $ x $ and $ y $-directions that is strongly dependent on the magnetic field and potential. Our numerical analysis show that the energy spectrum possesses a symmetry and the current density oscillates with different amplitudes under various conditions.
