Hyperspherical harmonics are extremely useful in nuclear physics and reactive scattering
theory. However, their use has been confined to specialists with very strong backgrounds in …

The nonlinear dynamics of self-bound Bose–Einstein matter waves under the action of an
attractive nonlocal and a repulsive local interaction is analyzed by means of a time …

By using a correlated many body method and using the realistic van der Waals potential we
study several statistical measures like the specific heat, transition temperature and the …

A two-body correlated basis set is used to develop a many-body theory which is valid for any
number of bosons in the trap. The formalism incorporates the van der Waals interaction and …

We have analytically explored both the zero temperature and the finite temperature scaling
theory for the collapse of an attractively interacting 3-D harmonically trapped Bose gas in a …

We present a correlated many-body approach to calculate the distribution function and
fluctuations for a Bose-Einstein condensate with N interacting atoms in the harmonic …

We present a statistical analysis of eigenenergies and discuss several measures of spectral
fluctuations and spectral correlations for the van der Waals clusters of different sizes. We …

We report the effects of interaction on thermodynamic properties of a repulsive Bose-
Einstein condensate confined in a harmonic trap by using the correlated potential harmonics …

A correlated many-body calculation is presented to characterize the Shannon information
entropy of trapped interacting bosons. We reformulate the one-body Shannon information …

We study the stability of attractive atomic Bose-Einstein condensate and the macroscopic
quantum many-body tunneling (MQT) in the anharmonic trap. We utilize correlated two-body …
