The shell evolution towards the extreme neutron-to-proton ratio has been a pivotal focus in nuclear physics over recent decades, since it is crucial to understand the effective nucleon-nucleon interactions and the r-process. Significant efforts have been devoted to deciphering the mechanism behind the shell evolution, such as the spin-orbit interaction, the tensor force, and the pseudospin...
When the entanglement structure of the quantum state of interest is non-uniform in real space, accurately representing the state with a limited number of degrees of freedom hinges on appropriately configuring the Tensor Network (TN) to align with the entanglement pattern. Although TN states including entanglement renormalization (ER) can encompass a wider variety of entangled states, a...
The generation and evolution of entanglement in many-body systems is an active area of research that spans multiple fields, from quantum information science to the simulation of quantum many-body systems encountered in condensed matter, subatomic physics, and quantum chemistry. Motivated by recent experiments exploring quantum information processing systems with electrons trapped above the...
The energy density functional method is able to provide systematic analysis on properties of nuclei all over the nuclear chart.
We perform the calculations for nuclei from the proton to the neutron drip lines including superheavy nuclei.
Using HFBTHO program(Axially deformed solution of the Skyrme-Hartree–Fock–Bogoliubov equations using the transformed harmonic oscillator basis (II)), the...
The rapid neutron capture process ($r$-process) is the most important mechanism for the synthesis of about half of the elements heavier than iron. It occurs in an environment with relatively high temperatures and high neutron densities. The abundances of the elements created by the $r$-process strongly depend on several nuclear inputs like masses, neutron capture rates, $\beta$-decay rates,...
The Gogny-type density functionals have finite-range and density-dependent terms. The parameters of the functionals are designed not only to reproduce the basic properties of finite nuclei but also to satisfy the saturation properties of nuclear matter. Consequently, calculations using a single density functionals can describe experimental data in various mass regions. However, the mean-field...
We study the quantum walk on the off-diagonal Aubry-André-Harper (AAH) lattice with periodic modulation using a digital quantum computer. We investigate various initial states at the single-particle level, considering different hopping modulation strengths and phase factors. Initiating the quantum walk with a particle at the lattice edge reveals the robustness of the edge state, attributed to...
In the inner crust of neutron stars, a Coulomb lattice of nuclei exists, immersed in a sea of superfluid neutron gas. The interplay between these nuclear crystals and the background neutrons may significantly alter nuclear dynamics, a phenomenon known as the "entrainment" effect, which is crucial for understanding several astronomical phenomena.
In our study, we have developed new...
In this study, we consider the treatments of short-range and long-range interactions in solid oxygen at the epsilon-zeta phase transition using the Hubbard U and van der Waals dispersion, respectively. We show that the London dispersion may correctly capture the nonlocal interactions in solid oxygen instead of the Hartree-Fock exchange [1]. The nonlocal effect is expected to be dominant at...
