Abstract Properties of strong coupled polaron in monolayer graphene are discussed in the presence of the Coulomb interaction. The linear combination operator method and Lee-Low-Pine unitary transformation method are used to calculate the first exited state energy of the polaron for various values of the electron-phonon coupling. It is shown that the first exited state energy of the system has a linear relationship with the magnetic field strength, the cut-off wave number, the Coulomb bound parameter, the distance between the graphene and the substrate.
