Anomalous collective modes in atomic nuclei within the proton-neutron interacting boson model

Wei Teng, Yu Zhang, Sheng-Nan Wang +3

Novel collective modes characterized by a $B_{4/2}$ ratio ( $\equiv B (E 2; 4_{1}^{+} \to 2_{1}^{+}) / B (E 2; 2_{1}^{+} \to 0_{1}^{+})$ ) less than 1.0 that were observed recently have been i…

Triaxial rotor modes in finite-N boson systems

Yu Zhang, ShengNan Wang, Feng Pan +2

We propose an algebraic approach to elucidate the dynamic characteristics of triaxial rotor modes in nuclei by mapping a triaxial rotor Hamiltonian to the interacting boson model (…

Algebraic description of the triaxially to axially rotational shape phase transition

Yu Zhang, Yu Xin Liu, Feng Pan +1

Within the framework of the interacting boson model, we propose a novel algebraic scheme to describe spin-dependent structural evolutions in triaxial nuclei. Our analysis demonstra…
