    "abstract": "Interaction of a two-level atom with a single mode of electromagnetic field\nincluding Kerr nonlinearity for the field and intensity-dependent atom-field\ncoupling is discussed. The Hamiltonian for the atom-field system is written in\nterms of the elements of a closed algebra, which has\n  SU(1,1) and Heisenberg-Weyl algebras as limiting cases. Eigenstates and\neigenvalues of the Hamiltonian are constructed.\n  With the field being in a coherent state initially, the dynamical behaviour\nof atomic-inversion, field-statistics and uncertainties in the field\nquadratures are studied. The appearance of nonclassical features during the\nevolution of the field is shown. Further, we explore the overlap of initial and\ntime-evolved field states.",
