Nonlinear Jaynes-Cummings model of atom-field interaction
S. Sivakumar
abstract: Interaction of a two-level atom with a single mode of electromagnetic field
including Kerr nonlinearity for the field and intensity-dependent atom-field
coupling is discussed. The Hamiltonian for the atom-field system is written in
terms of the elements of a closed algebra, which has
SU(1,1) and Heisenberg-Weyl algebras as limiting cases. Eigenstates and
eigenvalues of the Hamiltonian are constructed.
With the field being in a coherent state initially, the dynamical behaviour of
atomic-inversion, field-statistics and uncertainties in the field quadratures
are studied. The appearance of nonclassical features during the evolution of
the field is shown. Further, we explore the overlap of initial and time-evolved
field states.
