Multiphoton coherent states for bilayer graphene
arXiv:2209.00690 · doi:10.1088/1402-4896/acc0ae
Abstract
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.
