Atomic nuclei are complex systems of nucleons–protons and neutrons. Nucleons interact
with each other via an attractive and short-range force. This feature of the interaction leads to …

We use an ensemble of random but spin-and isospin-invariant interactions in a restricted
orbital space as a tool for exploration of the shell-model parameter space to understand the …

Quantum chaos has become an important element of our knowledge about physics of
complex systems. In typical mesoscopic systems of interacting particles the dynamics …

An ensemble with random n-body interactions is investigated in the presence of symmetries.
A striking emergence of regularities in the spectra, ground state spins, and isospins is …

Bosonic degrees of freedom and their emergence as part of complex quantum many-body
dynamics, symmetries, collective behavior, clustering, and phase transitions play an …

In this paper we study collective motion under random two-body interactions in the fermion
dynamical symmetry Model (FDSM). It is found that a Hamiltonian with the SO (8) symmetry …

In this paper we study yrast states of sd bosons under random interactions by revisiting the
collective motions and the linear correlations in the Mallmann plot. Both the SU (3) and the …

In this article we study the behavior of collectivity under random two-body interactions in the
framework of the fermion dynamical symmetry model (FDSM). We found that a Hamiltonian …

In this work we study the yrast states of sd-boson systems in the presence of random
interactions. It is found that the yrast states with spin-zero ground states among the random …

We conduct a systematic investigation of the nuclear collective dynamics that emerges in
systems with two-body random interactions. We explore the development of the mean field …
