Surface-enhanced pair transfer in quadrupole states of neutron-rich Sn isotopes

, 2010
We investigate the neutron pair transfer modes associated with the low-lying quadrupole states in neutron-rich Sn isotopes by means of the quasiparticle random phase approximation based on the Skyrme-Hartree-Fock-Bogoliubov mean field model.

Transition quadrupole moments in superdeformed bands

Physics of Atomic Nuclei, 2000
We propose a method to select core and cluster in a binary component description of atomic nuclei. The choice is based on the mismatch between measured binding energies and the underlying trend supplied by the liquid drop model. A key point is that the charge to mass ratios of parent, core, and cluster should be as nearly equal as possible.

Description of superdeformed nuclei in the interacting boson model

, 1995
The interacting boson model is extended to describe the spectroscopy of superdeformed bands. Microscopic structure of the model in the second minimum is discussed and superdeformed bosons are introduced as the new building blocks.

Inelastic scattering reaction as a probe for monopole, dipole and quadrupole excitations [PDF]

EPJ Web of Conferences
The study of collective motions within atomic nuclei, such as monopole, dipole, and quadrupole excitations, is crucial for understanding nuclear structure and properties, which provide insights into the spatial distribution and dynamic nature of protons ...

Shape transition with temperature of the pear-shaped nuclei in covariant density functional theory

, 2017
The shape evolutions of the pear-shaped nuclei $^{224}$Ra and even-even $^{144-154}$Ba with temperature are investigated by the finite-temperature relativistic mean field theory with the treatment of pairing correlations by the BCS approach.

A Note on the Toda Criterion for Interacting Dipole-Quadrupole Vibrations [PDF]

, 1997
The Toda criterion of the Gaussian curvature is applied to calculate analytically the transition energy from regular to chaotic motion in a schematic model describing the interaction between collective dipole and quadrupole modes in atomic nuclei.Comment:

Atomic circulation in evanescent of LG10 mode with active dipole and quadrupole transitions

Journal of Taibah University for Science
The total internal reflection of a light with phase singularity, such as Laguerre–Gaussian (LG) light, can generate an evanescent wave. The distribution of this type of light is firmly localized in the vicinity above the dielectric surface and displays a

Zigzag chain structure transition and orbital fluctuations in Ni-based superconductors

, 2013
We investigate the electronic state and structure transition of BaNi2As2, which shows a similar superconducting phase diagram as Fe-based superconductors.

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...
