Localization-Delocalization Transitions in Bosonic Random Matrix Ensembles
N. D. Chavda, V. K. B. Kota
Localization to delocalization transitions in eigenfunctions are studied for finite interacting boson systems by employing one- plus two-body embedded Gaussian orthogonal ensemble…
Probability Distribution of the Ratio of Consecutive Level Spacings in Interacting Particle Systems
N. D. Chavda, V. K. B. Kota
We study the probability distribution of the ratio of consecutive level spacings for embedded one plus two-body random matrix ensembles with and without spin degree of freedom and…
Random matrix ensemble with random two-body interactions in presence of a mean-field for spin one boson systems
H. N. Deota, N. D. Chavda, V. K. B. Kota +2
For number of bosons, carrying spin (=1) degree of freedom, in number of single particle orbitals, each triply degenerate, we introduce and analyze embedded Gaussian ort…
Thermalization in one- plus two-body ensembles for dense interacting boson systems
N. D. Chavda, V. K. B. Kota, V. Potbhare
Employing one plus two-body random matrix ensembles for bosons, temperature and entropy are calculated, using different definitions, as a function of the two-body interaction stren…

Nature of matrix elements in the quantum chaotic domain of interacting particle systems
V. K. B. Kota, R. Sahu
There is a newly emerging understanding that in the chaotic domain of isolated finite interacting many particle systems smoothed densities define the statistical description of the…
