The temperature-dependent chiral-induced spin selectivity effect: Experiments and theory
Tapan Kumar Das, Francesco Tassinari, Ron Naaman +1
The theoretical explanation for the chiral-induced spin selectivity effect, in which electrons' passage through a chiral system depends on their spin and the handedness of the syst…
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…
Condensate fraction and critical temperature of interacting Bose gas in anharmonic trap
Sudip Kumar Haldar, Barnali Chakrabarti, Satadal Bhattacharyya +1
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…
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…
Correlated many-body calculation to study characteristics of Shannon information entropy for ultracold trapped interacting bosons
Sudip Kumar Haldar, Barnali Chakrabarti, Tapan Kumar Das +1
A correlated many-body calculation is presented to characterize the Shannon information entropy of trapped interacting bosons. We reformulate the one-body Shannon information entro…
Supersymmetric isospectral formalism for the calculation of near-zero energy states: application to the very weakly bound He trimer excited state
Sudip Kumar Haldar, Barnali Chakrabarti, Tapan Kumar Das
We propose a novel mathematical approach for the calculation of near-zero energy states by solving potentials which are isospectral with the original one. For any potential, famili…
