Spacetime discreteness via consistent microscopic measurement
Weihu Ma, Yu-Gang Ma
The physical origin of spacetime discreteness remains a central open problem in quantum gravity, with most existing approaches relying on specific microscopic structures or model-d…
Scaling-Based Quantization of Spacetime Microstructure
Weihu Ma, Yu-Gang Ma
Planck-scale physics challenges the classical smooth-spacetime picture by introducing quantum fluctuations that imply a nontrivial spacetime microstructure. We present a framework…
Probing Nucleon-Interaction via Lattice QCD at Physical Quark Masses
Liang Zhang, Takumi Doi, Yan Lyu +2
We study the S-wave interactions between the nucleon () and the triply charmed Omega baryon () using (2+1)-flavor lattice QCD with a physical pion mass ($m_Ï…
Branching ratio and information entropy for the p+C reaction in the extended-quantum-molecular-dynamics model
Lei Shen, Bo-Song Huang, Yu-Gang Ma
The reactions of p+C with triangular 3 structure and spherical structure with incident energies ranging from 5 to 200 MeV/nucleon are simulated by the in the extended-qu…
Probing Nuclear Excitation by Electron Capture in an Electron Beam Ion Trap with Non-destructive Isomer Detection via Precision Mass Spectrometry
Bingsheng Tu, Nan Xue, Jialin Liu +10
Nuclear excitation by electron capture (NEEC) is an important nuclear excitation mechanism which still lacks conclusive experimental verification. This is primarily attributed to s…
Activation of momentum fluctuations in wave packet molecular dynamics: Impacts on momentum distributions of projectilelike fragments
Lei Shen, Akira Ono, Yu-Gang Ma
Molecular dynamics approaches use wave packets as nucleon wave functions to simulate the time evolution of nuclear reactions. It is crucial to activate the momentum fluctuation inh…
