Quantum dynamical model for laser excitation of a two-level adatom: Surface-dressed Bloch equations

Surface-dressed Bloch equations are derived from a microscopic Hamiltonian which includes the interactions among an adatom, the laser photon and the phonon modes. The influence of the surface on the population inversion of the adatom is analyzed in terms of: (1) the reflected-field-induced damping f...

Description
Summary:Surface-dressed Bloch equations are derived from a microscopic Hamiltonian which includes the interactions among an adatom, the laser photon and the phonon modes. The influence of the surface on the population inversion of the adatom is analyzed in terms of: (1) the reflected-field-induced damping factor which depends on the orientation of the transition dipole and the adatom-surface separation and (2) the frequency shift and damping factor induced by the phonon modes.
