Tetrahedral shape of Zr from covariant density functional theory in 3D lattice space
Fangfang Xu, Bo Li, Zhengxue Ren +1
Covariant density functional theory is solved in 3D lattice space by implementing the preconditioned conjugate gradient method with a filtering function (PCG-F). It considerably im…
Ab initio study of nuclear clustering in hot dilute nuclear matter
Zhengxue Ren, Serdar Elhatisari, Timo A. Lähde +2
We present a systematic ab initio study of clustering in hot dilute nuclear matter using nuclear lattice effective field theory with an SU(4)-symmetric interaction. We introduce a…
Accurate relativistic density functional for exchange energy of atomic nuclei
Qiang Zhao, Zhengxue Ren, Pengwei Zhao +1
The inclusion of nucleonic exchange energy has been a long-standing challenge for the relativistic density functional theory (RDFT) in nuclear physics. We propose an orbital-depend…
Covariant Density Functional Theory with Localized Exchange Terms
Qiang Zhao, Zhengxue Ren, Pengwei Zhao +1
A new density-dependent point-coupling covariant density functional PCF-PK1 is proposed, where the exchange terms of the four-fermion terms are local and are taken into account wit…
First observation of excited states
LHCb collaboration, R. Aaij, C. Abellán Beteta +901
We report four narrow peaks in the mass spectrum obtained using collisions at center-of-mass energies of 7, 8 and 13 TeV, corresponding to a total integrated lumino…
Solving Dirac equations on a 3D lattice with inverse Hamiltonian and spectral methods
Z. X. Ren, S. Q. Zhang, J. Meng
A new method to solve the Dirac equation on a 3D lattice is proposed, in which the variational collapse problem is avoided by the inverse Hamiltonian method and the fermion doublin…
