Ordered Level Spacing Distribution in Embedded Random Matrix Ensembles
Priyanka Rao, H. N. Deota, N. D. Chavda
The probability distribution of the closest neighbor and farther neighbor spacings from a given level have been studied for interacting fermion/boson systems with and without spin…
Structure of wavefunction for interacting bosons in mean-field with random -body interactions
Priyanka Rao, N. D. Chavda
Wavefunction structure is analyzed for dense interacting many-boson systems using Hamiltonian , which is a sum of one-body and an embedded GOE of -body interaction $V(…
Distribution of Higher Order Spacing Ratios in Interacting Many Particle Systems
Priyanka Rao, Manan Vyas, N. D. Chavda
We study the distribution of non-overlapping spacing ratios of higher-orders for complex interacting many-body quantum systems, with and without spin degree of freedom (in addition…
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…
Fidelity decay and entropy production in many-particle systems after random interaction quench
Sudip Kumar Haldar, N. D. Chavda, Manan Vyas +1
We analyze the effect of spin degree of freedom on fidelity decay and entropy production of a many-particle fermionic(bosonic) system in a mean-field, quenched by a random two-body…
Poisson to GOE transition in the distribution of the ratio of consecutive level spacings
N. D. Chavda, H. N. Deota, V. K. B. Kota
Probability distribution for the ratio () of consecutive level spacings of the eigenvalues of a Poisson (generating regular spectra) spectrum and that of a GOE random matrix ens…
