Vv. Klimov et al., VACUUM RABI SPLITTING OF ENERGY-LEVELS IN A STRONGLY COUPLED SYSTEM OF A 2-LEVEL ATOM AND DIELECTRIC MICROSPHERE, Physical review. A, 56(3), 1997, pp. 2308-2315
The effective dipolar Hamiltonian and the vacuum Rabi frequency for a
system with a dielectric microsphere and a two-level atom with arbitra
ry orientation of dipole momentum are found. The energy levels of such
a system are determined within the rotating-wave approximation as wel
l as by numerical methods. The solution found is close to that within
the pure classical approach.
