A case study is made of the delocalisation and revival dynamics of a continuously driven quantum pendulum in integrable and near integrable regimes, utilising the Husimi phase-space distribution function, and an entropy function which measures the degree of localisation. The numerical results...

In our earlier work (Xie et al., Physica A 246 (1997) 529), the concept of higher-order atomic dipole squeezing (HOADS) was introduced. In this paper, we study further the effect of the dynamic Stark shift on HOADS in the two-photon Jaynes–Cummings model for a two-level atom initially prepared...

Allometry is crucial in biology; scaling relations are implied in laws of growth of living systems. The self similarity of Gompertzian growths of biological organisms plays a key role, in this regard, in biological similitude. The origin of allometric relationships and values of the scaling...

In our preceding work (Physica A 246 (1997) 529), the concept of higher-order atomic dipole squeezing (HOADS) was introduced. In this paper, we discuss further the influence of the nonlinear interaction of a two-level atom with a single-mode radiation field via one-photon processes on the...
