Supercritically charged objects and electron-positron pair creation
@inproceedings{Xia2020SupercriticallyCO, title={Supercritically charged objects and electron-positron pair creation}, author={Cheng-Jun Xia and She-Sheng Xue and Renxin Xu and Shan-Gui Zhou}, year={2020} }
We investigate the stability and $e^+e^-$ pair creation of supercritical charged superheavy nuclei, $ud$QM nuggets, strangelets, and strangeon nuggets based on Thomas-Fermi approximation. The model parameters are fixed by reproducing their masses and charge properties reported in earlier publications. It is found that $ud$QM nuggets, strangelets, and strangeon nuggets may be more stable than ${}^{56}$Fe at $A\gtrsim 315$, $5\times10^4$, and $1.2\times10^8$, respectively. For those stable…

The possible existence of stable up-down quark matter (udQM) was recently proposed, and it was shown that the properties of udQM stars are consistent with various pulsar observations. In this work we…

We investigate interacting quark matter (IQM), including the perturbative QCD correction and color superconductivity, for both up-down quark matter ($ud$QM) and strange quark matter (SQM). We first…
Quantum nucleation of up-down quark matter and astrophysical implications
- Physics

Quark matter with only $u$ and $d$ quarks ($ud$QM) might be the ground state of baryonic matter at large baryon number $A>A_{\rm min}$. With $A_{\rm min}\gtrsim 300$, this has no direct conflict with…

A model describing the hadronization of the QGP through particle emission, which is based solely on thermodynamical arguments, and two rather unexpected results are obtained when this model is applied to the investigation of strangelet production.
Binary Neutron Star Mergers: Mass Ejection, Electromagnetic Counterparts, and Nucleosynthesis

We present a systematic numerical relativity study of the mass ejection and the associated electromagnetic transients and nucleosynthesis from binary neutron star (NS) mergers. We find that a few…

The \ensuremath{\alpha} decay half-lives of the recently produced isotopes of the 112, 114, 116 and 118 nuclei and decay products have been calculated in the quasi-molecular shape path using the…

As is pointed out in a recent work (Phys. Rev. Lett. 120, 222001), quark matter may not be strange. Inspired by this argument, we use a new self-consistent mean field approximation method to study…

We construct strangelets, taking into account electrostatic effects, including Debye screening, and arbitrary surface tension {sigma} of the interface between vacuum and quark matter. We find that…
