Phases, many-body entropy measures and coherence of interacting bosons in optical lattices
R. Roy, A. Gammal, M. C. Tsatsos +3
Already a few bosons with contact interparticle interactions in small optical lattices feature a variety of quantum phases: superfluid, Mott-insulator and fermionized Tonks gases c…
Characteristic features of the Shannon information entropy of dipolar Bose-Einstein condensates
Thangarasu Sriraman, Barnali Chakrabarti, Andrea Trombettoni +1
Calculation of the Shannon information entropy (S) and its connection with the order-disorder transition, and with inter-particle interaction provide a challenging research area in…
Role of conditional shape invariance symmetry property to obtain eigen-spectrum of the generalized polynomial potential with a Coulomb term
Sudesna Bera, Rajesh Kumar Yadav, Barnali Chakrabarti +1
A method based on supersymmteric (SUSY) quantum mechanics has been developed by exploiting conditional Shape invariance property for obtaining exact ground state solution of genera…
Spectral analysis of molecular resonances in erbium isotopes: Are they close to semi-Poisson?
Kamalika Roy, Barnali Chakrabarti, N. D. Chavda +3
We perform a thorough analysis of the spectral statistics of experimental molecular resonances, of bosonic erbium Er and Er isotopes, produced as a function of magn…
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…
