Transverse WardTakahashi identities and full vertex functions in different representations of QED_{3}
2020, 44(7): 073105. doi: 10.1088/16741137/44/7/073105We derive the transverse WardTakahashi identities (WTI) of Ndimensional quantum electrodynamics by means of the canonical quantization method and the path integration method, and subsequently attempt to prove that QED_{3} is solvable based on the transverse and longitudinal WTI, indicating that the full vector and tensor vertices functions can be expressed in terms of the fermion propagators in QED_{3}. Further, we discuss the effect of different γ matrix representations on the full vertex function.

A new method to test the cosmic distance duality relation using the strongly lensed gravitational waves
2020, 44(7): 075101. doi: 10.1088/16741137/44/7/075101We propose a new method to test the cosmic distance duality relation using the strongly lensed gravitational waves. The simultaneous observation of the image positions, relative time delay between different images, redshift measurements of the lens and the source, together with the mass modelling of the lens galaxy, provide the angular diameter distance to the gravitational wave source. On the other hand, the luminosity distance to the source can be obtained from the observation of the gravitational wave signals. To our knowledge this is the first time a method is proposed to simultaneously measure the angular diameter distance and the luminosity distance from the same source. Hence, the strongly lensed gravitational waves provide a unique method to test the cosmic distance duality relation. With the construction of the third generation gravitational detectors such as the Einstein Telescope, it will be possible to test the cosmic distance duality relation with an accuracy of a few percent.

Evolution of intrinsic nuclear structure in medium mass eveneven Xenon isotopes from a microscopic perspective
2020, 44(7): 074108. doi: 10.1088/16741137/44/7/074108In this study, the multiquasiparticle triaxial projected shell model (TPSM) is applied to investigate
$\gamma$ vibrational bands in transitional nuclei of$^{118128}{\rm{Xe}}$ . We report that each triaxial intrinsic state has a$\gamma$ band built on it. The TPSM approach is evaluated by the comparison of TPSM results with available experimental data, which shows a satisfactory agreement. The energy ratios, B(E2) transition rates, and signature splitting of the$\gamma$ vibrational band are calculated.

Singleparticle resonant states with Green’s function method
Published: 20200713, doi: 10.1088/16741137/44/8/084105Show AbstractThis study employs the relativistic mean field theory with the Green's function method to study the singleparticle resonant states. In contrast to our previous work [Phys. Rev. C, 90: 054321 (2014)], the resonant states are identified by searching for the poles of Green's function or the extremes of the density of states. This new approach is highly effective for all kinds of resonant states, no matter whether they are broad or narrow. The dependence on the space size for the resonant energies, widths, and the density distributions in the coordinate space has been checked and was found to be very stable. Taking ^{120}Sn as an example, four new broad resonant states
$ 2g_{7/2} $ ,$ 2g_{9/2} $ ,$ 2h_{11/2} $ , and$ 1j_{13/2} $ were observed, and the accuracy for the width of the very narrow resonant state$ 1h_{9/2} $ was highly improved to$ 1\times 10^{8} $ MeV. Further, our results are very close to those obtained using the complex momentum representation method and the complex scaling method. 
2νββdecay to first 2^{+} states with partial isospin symmetry restoration from spherical QRPA calculations
Published: 20200713, doi: 10.1088/16741137/44/8/084104Show AbstractUsing partially restored isospin symmetry, we calculate the nuclear matrix elements for a special decay mode of a twoneutrino double beta decay – the decay to the first 2^{+} excited states. Employing the realistic CD–Bonn nuclear force, we analyze the dependence of the nuclear matrix elements on the isovector and isoscalar parts of proton–neutron particle–particle interactions. The dependence on the different nuclear matrix elements is observed, and the results are explained. We also provide the phase space factors using numerical electron wavefunctions and properly chosen excitation energies. Finally, we present our results for the halflives of this decay mode for different nuclei.

Analysis of survival probability based on superasymmetric reaction systems
Published: 20200710, doi: 10.1088/16741137/44/9/094102Show AbstractThe survival probability of an excited compound nucleus was studied using two different approaches of the washing out of shell effects with excitation energy based on a superasymmetric reaction system. The estimated evaporation residue cross sections based on the two different methods are compared with the available experimental data. Both methods are in agreement with the experimental data to a certain extent for some specific reactions and
$ xn$ emission channels.
