Application of conditional shape invariance symmetry to obtain the eigen-spectrum of the mixed potential V (r) = ar + br^2 + c/r + l(l+1)/r^2
Sudesna Bera, Barnali Chakrabarti, Tapan Kumar Das
We show that the conditional shape invariance symmetry can be used as a very powerful tool to calculate the eigenvalues of the mixed potential V (r) = ar + br^2 +c/r + l(l+1)/r^2 f…
Level spacing statistics and spectral correlations in the diffuse van der Waals clusters
Sudip Kumar Haldar, Barnali Chakrabarti, N. D. Chavda +3
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…
Potential Harmonics Expansion Method for Trapped Interacting Bosons : Inclusion of Two-Body Correlation
T. K. Das, B. Chakrabarti
We study a system of identical interacting bosons trapped by an external field by solving ab initio the many-body Schroedinger equation. A complete solution by using, for examp…
