论文摘要
多光子相干状态，一种对相干元素的概括，是针对位于恒定均匀磁场的双层石墨烯中的电子的，该磁场与双层表面正交。为此，为了确定具有复杂特征值的运算符的多光子相干状态，建造了广义的歼灭操作员。此外，根据海森堡的不确定性关系，概率密度和平均能量值，计算了这些状态的一些物理量。最后，为了研究系统的动力学，探索了时间演化并计算时间相关函数。
The multiphoton coherent states, a generalization to coherent sates, are derived for electrons in bilayer graphene placed in a constant homogeneous magnetic field which is orthogonal to the bilayer surface. For that purpose a generalized annihilation operator is constructed in order to determine the multiphoton coherent states as eigenstates of such operator with complex eigenvalue. In addition, some physical quantities are calculated for these states, as the Heisenberg uncertainty relation, probability density and mean energy value. Finally, in order to study the dynamics of the system the time evolution is explored and the time-correlation function is computed.
