A new parametrization PC-PK1 for the nuclear covariant energy density functional with nonlinear point-coupling interaction is proposed by fitting to observables 60 selected spherical nuclei, including binding energies, charge radii and empirical pairing gaps. The success of illustrated in its description infinite matter finite nuclei ground-state low-lying excited states. Particularly, improves isospin dependence along either isotopic or isotonic chains, which makes it more reliable...
By taking into account the surface diffuseness correction for unstable nuclei, accuracy of macroscopic-microscopic mass formula is further improved. The rms deviation with respect to essentially all available data falls 298 keV, crossing 0.3 MeV threshold first time within mean-field framework. Considering effect symmetry potential which plays an important role in evolution "neutron skin" toward halo" nuclei approaching neutron drip line, we obtain optimal value energy coefficient J=30.16...
Relativistic Hartree-Bogoliubov theory in coordinate space is used to describe the chain of lithium isotopes reaching from ${}^{6}$Li ${}^{11}$Li. Pairing correlations are taken into account by a density dependent force zero range. In contrast earlier investigations within relativistic mean field and Hartree-Fock theory, where halo ${}^{11}$Li could only be reproduced an artificial shift ${1p}_{1/2}$ level close continuum limit, now self-consistent way, without further modifications, using...

They able to provide an excellent description not only properties of nuclear matter but also nuclei far from valley $\ensuremath{\beta}$ stability. For first time parametrization...
A lattice QCD computation close to the physical point finds a near-threshold virtual state in $D\phantom{\rule{0}{0ex}}{D}^{*}$ scattering channel, that suggests formation of loosely bound at consistent with experimental observation doubly charmed tetraquark ${T}_{c\phantom{\rule{0}{0ex}}c}^{+}$.

In the present study, we employ three distinct, physically motivated speed of sound bounds to construct hybrid models, where high-density phase is described by maximally stiff equation state. particular, consider related special relativity, relativistic kinetic theory, and conformality.

Relating the pseudospin symmetry back to Dirac equation through framework of relativistic Hartree-Bogoliubov (RHB) theory, approximation in real nuclei is discussed. From equation, mechanism behind was studied and shown be connected with competition between centrifugal barrier (CB) orbital potential (PSOP), which mainly decided by derivative difference scalar vector potentials. With potentials derived from a self-consistent calculation, its energy dependence

Cisplatin is a chemotherapeutic drug commonly used in clinics. However, acquired resistance confines its application chemotherapeutics. To overcome the to cisplatin, it reasoned, based on our previous findings of mediation cellular responses by [Gd@C 82 (OH) 22 ] n nanoparticles, that may reverse tumor cisplatin reactivating impaired endocytosis cisplatin-resistant human prostate cancer (CP-r) cells.

Adiabatic and configuration-fixed constrained triaxial relativistic mean field (RMF) approaches are developed for the first time. A new phenomenon, existence of multiple chiral doublets (M\ensuremath{\chi}D), i.e., more than one pair doublet bands in single nucleus, is suggested $^{106}\mathrm{Rh}$ based on deformations their corresponding proton neutron configurations.
We discuss spin and pseudospin symmetry in the spectrum of single nucleons antinucleons a nucleus. As an example we use relativistic mean field theory to investigate antinucleon spectra. find very well developed antineutron antiproton The dominant components wave functions doublet are almost identical. This antiparticle spectra particle have same origin. However, it turns out that is much better than normal nuclear
A new relativistic Hartree-Fock approach with density-dependent $\sigma$, $\omega$, $\rho$ and $\pi$ meson-nucleon couplings for finite nuclei nuclear matter is presented. Good description achieved a number of adjustable parameters comparable to that the mean field approach. With Fock terms, contribution $\pi$-meson included nucleon effective mass its isospin energy dependence improved.
Halo phenomena in deformed nuclei are investigated within a relativistic Hartree Bogoliubov (DRHB) theory. These weakly bound quantum systems present interesting examples for the study of interdependence between deformation core and particles halo.

The Woods-Saxon basis has been suggested to replace the widely used harmonic oscillator for solving relativistic mean field (RMF) theory in order generalize it study exotic nuclei. As examples, Hartree is solved spherical nuclei a obtained by either Schr\"odinger equation or Dirac (labelled as SRHSWS and SRHDWS, respectively SRHWS both). In negative levels Sea must be properly included. SRHDWS could smaller than that which will simplify deformed problem. results from are compared detail with...
