论文摘要
我们重新审视浸入该层均匀均匀磁场正交中的单轴紧张的石墨烯，以描述由半古典模型构建的相干状态的时间演变。我们考虑对称量规矢量的潜力来呈现磁场，并在各向异性参数$ζ$上编码拉伸和压缩变形。在用各向异性费米速度求解狄拉克状方程后，我们定义了一组基质梯子操作员，并将电子相干状态构造为具有复杂特征值的基质歼灭算子的特征状态。通过相应的概率密度，我们能够研究这些状态对$ xy $平面的各向异性影响以及它们的时间演变。我们的结果清楚地表明，电子相干状态的准周期受单轴菌株的影响。
We revisit the uniaxially strained graphene immersed in a uniform homogeneous magnetic field orthogonal to the layer in order to describe the time evolution of coherent states build from a semi-classical model. We consider the symmetric gauge vector potential to render the magnetic field, and we encode the tensile and compression deformations on an anisotropy parameter $ζ$. After solving the Dirac-like equation with an anisotropic Fermi velocity, we define a set of matrix ladder operators and construct electron coherent states as eigenstates of a matrix annihilation operator with complex eigenvalues. Through the corresponding probability density, we are able to study the anisotropy effects on these states on the $xy$-plane as well as their time evolution. Our results show clearly that the quasi-period of electron coherent states is affected by the uniaxial strain.
