Abstract X-ray bursts are among the brightest stellar objects frequently observed in sky by space-based telescopes. A type-I burst is understood as a violent thermonuclear explosion on surface of neutron star, accreting matter from companion star binary system. The powered nuclear reaction sequence known rapid proton capture process (rp process), which involves hundreds exotic neutron-deficient nuclides. At so-called waiting-point nuclides, stalls until slower β + decay enables bypass. One...
Using a novel method of isochronous mass spectrometry, the masses $^{62}\mathrm{Ge}$, $^{64}\mathrm{As}$, $^{66}\mathrm{Se}$, and $^{70}\mathrm{Kr}$ are measured for first time, $^{58}\mathrm{Zn}$, $^{61}\mathrm{Ga}$, $^{63}\mathrm{Ge}$, $^{65}\mathrm{As}$, $^{67}\mathrm{Se}$, $^{71}\mathrm{Kr}$, $^{75}\mathrm{Sr}$ redetermined with improved accuracy. The new allow us to derive residual proton-neutron interactions ($\ensuremath{\delta}{V}_{pn}$) in $N=Z$ nuclei, which found decrease...
Isospin-symmetry breaking is responsible for the energy difference of excited states in mirror nuclei. It also influences coefficient isobaric multiplet mass equation. In present work, we extensively investigate isospin-symmetry medium-mass nuclei within ab initio frameworks. For this, employ valence-space in-medium similarity renormalization group approach, which charge-symmetry and charge-independence breakings are included adopted nuclear force. The energies $sd$- $pf$-shell computed that...
With both three-nucleon force and continuum coupling included, we have developed a self-consistent {\it ab initio} Gamow shell model within the Hartree-Fock (GHF) basis obtained by realistic interaction itself. chiral two-nucleon N$^3$LO N$^2$LO interactions, has been applied to mirror systems of $Z=8$ neutron-rich isotopes $N=8$ proton-rich isotones, giving good agreements with data in binding energies, dripline positions excitation spectra. The GHF calculated that $0d_{3/2}$, $1s_{1/2}$...
We have developed an {\it ab initio} deformed in-medium similarity renormalization group (IMSRG) for open-shell nuclei. This is a single-reference IMSRG in Hartree-Fock (HF) basis. Deformed wave functions are more efficient describing The broken spherical symmetry needs to be restored by angular momentum projection, which computational expensive. mainly capture the static correlations and can estimated projection of HF state. In this work, we do calculation add correlation energy from...
Nuclear physics provides a natural laboratory for studying two kinds of fermions: protons and neutrons. These particles share similarities in mass strong nuclear interactions, which are often described by isospin symmetry. However, is not good quantum number due to the differences between neutrons charge quark mass. become more pronounced as we approach or move beyond dripline, affecting structures decay properties mirror nuclei. To explore these intriguing phenomena, researchers have...
New magic numbers have been discovered in the neutron-rich region of nuclear chart. However, there has a lack research on proton-rich nuclei. 22O, mirror nucleus 22Si, is double-magic bearing high E(21+). Whether 22Si exhibits characters an intriguing topic. To investigate this matter, we utilized ab initio valence space in-medium similarity renormalization group for 22Si/22O, and their nearby Our calculations provide good descriptions double magicity as well shell evolution N=14 Z=14...
Starting from chiral two-nucleon (2NF) and three-nucleon (3NF) potentials, we present a detailed study of 17Ne, Borromean system, with the Gamow shell model which can capture continuum effects. More precisely, take advantage normal-ordering approach to include 3NF Berggren representation treat bound, resonant states on equal footing in complex-momentum plane. In our framework, is essential reproduce structure while more crucial for halo property nucleus. The two-proton demonstrated by...
Nuclei in the vicinity of driplines have been receiving a lot attention nuclear structure studies. In nuclei, continuum coupling is crucial reproducing weakly bound and unbound phenomena. To calculate observables nuclei as open quantum systems, we developed valence-space effective operators complex-energy Berggren basis using many-body perturbation theory. We focus on Gamow-Teller $\ensuremath{\beta}$ decay $\mathit{sd}$ shell. The two- plus three-nucleon force from chiral field theory,...
We have used an ab initio Gamow shell model to study the isospin symmetry breaking in $A=16$ mirror nuclei of $^{16}\mathrm{F}, ^{16}\mathrm{N}, ^{16}\mathrm{Ne}$, and $^{16}\mathrm{C}$. Starting from a chiral interaction with two-nucleon force (2NF) at ${\mathrm{N}}^{3}\mathrm{LO}$ three-nucleon (3NF) ${\mathrm{N}}^{2}\mathrm{LO}$, complex-momentum psd-shell Hamiltonian was constructed by employing many-body perturbation theory Hartree-Fock basis which includes bound, resonant, continuum...
Ab initio calculations have achieved remarkable success in nuclear structure studies. Numerous works highlight the pivotal role of three-body forces ab calculations. Concurrently, efforts been made to replicate these using only realistic nucleon-nucleon $(NN)$ interactions. A novel local chiral next-to-next-to-next-to-leading order $({\mathrm{N}}^{3}\mathrm{LO})$ $NN$ interaction, distinct due its weaker tensor force, has recently established. This paper applies this interaction frameworks...
Neutron-rich nuclei are attracting significant attention due to vital roles in the nucleosynthesis processes of universe. The shell evolution which breaks or creates magic numbers some instances leads shape coexistence that frequently serves as a portal islands inversion (IOI). $^{74}\mathrm{Zn}$ was suggested northern extension $N=40$ IOI across $Z=28$, and new around $N=50$ ($Z=20$--28) had also been predicted. We have performed ab initio calculations for even-even Zn isotopes ($Z>28$)...
Neutron-rich carbon isotopes have been investigated within the Gamow shell model (GSM) based on a realistic nuclear force. $^{14}\mathrm{C}$ was chosen as core in shell-model calculations of neutron-rich isotopes. The effect from coupling to continuum is well considered by using complex-momentum Berggren representation which treats bound, resonant, and states an equal footing. Using many-body perturbation theory named $\stackrel{\ifmmode \hat{}\else \^{}\fi{}}{Q}$-box folded-diagram method,...
We present a numerical study to late times of Richtmyer–Meshkov environment: weak shock ( M = 1.095) interacting with heavy cylindrical bubble. The bubble interface is modeled as diffuse interfacial transition layer (ITL) finite thickness. Our simulation the piecewise parabolic method (PPM) yields very good agreement in large- and intermediate-scale features Jacobs' experiment (Jacobs, 1993). note primary circulation enhancement deposited baroclinically upon incident wave, significant...
<p indent="0mm">Proton-rich nuclei exhibit many novel phenomena, such as proton emission, halo, and Thomas-Ehrman shift. On one hand, due to the Coulomb force, outer protons have a lower nuclear separation threshold are strongly coupled continuum. Such weakly bound called open quantum system. other barrier restricts spatial spread of weakly-bound protons, resulting in that unbound resonance beyond drip line may certain lifetimes, e.g., millisecond lifetime. The interplay continuum coupling...
We examine the interaction of both cylindrical and spherical bubbles (2D) a complex blast wave, which consists an approaching shock/contact discontinuity/shock (Kang et al. , 2001 b ). Such configurations may arise following supernova explosion, for example, SN 1987A, where wave is presently high density “circumstellar ring” (CR) (Borkowski 1997). Using simulations with piecewise parabolic method algorithm (Colella & Woodward, 1984), we emphasize appearance vortex bilayers, projectiles,...
We suggest an easily obtained laboratory configuration to observe jet and vortex flows for the Richtmyer–Meshkov (accelerated inhomogeneous flow) environment. A hemispherical bubble in air with density ratio of 5 is placed against ideally reflecting wall struck by a planar shock. This also models spherical symmetrically two identical approaching shocks, that is, “reshock” configuration. For all Mach numbers ( M = 1.2, 1.5, 2.0), our axisymmetric simulations show heavy expands axially away...

Starting from a chiral interaction with two-nucleon force (2NF) at N$^3$LO three-nucleon (3NF) N$^2$LO, complex-momentum ${\it psd}$-shell Hamiltonian was constructed by employing many-body perturbation theory Hartree-Fock basis which includes bound, resonant continuum states self-consistently. Such elaborated both coupling 3NF...

For case, its behavior mainly presents three kinds contributions: one, as finite term viewed interaction term, comes from conserved charge, second one is spatial volume third relates curvature horizon black hole, where effect plays...
One of the most interesting anomalies in nuclear physics is island inversion (IOI), which indicates that magic numbers disappear. It provides a good platform to understand single-particle motion, many-body correlation, and nucleon-nucleon interaction. In neutron-rich isotopes near N =20 area, many experiments have found spectra, electromagnetic transitions, radii, two-neutron separation energies these nuclei are abnormal. This region called IOI, because it characterized by neutron...
