Supercritically charged objects and electron-positron pair creation

  title={Supercritically charged objects and electron-positron pair creation},
  author={Cheng-Jun Xia and She-Sheng Xue and Renxin Xu and Shan-Gui Zhou},
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…

Stable Up-Down Quark Matter Nuggets, Quark Star Crusts, and a New Family of White Dwarfs
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
Unified interacting quark matter and its astrophysical implications
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
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


Bare Quark Matter Surfaces of Strange Stars and e + e − Emission
We show that the Coulomb barrier at the quark surface of a hot strange star may be a powerful source of $e^+e^-$ pairs which are created in an extremely strong electric field of the barrier and flow
Strangeons constitute bulk strong matter: Test using GW 170817
Abstract.The fundamental strong interaction determines the nature of pulsar-like compact stars which are essentially in the form of bulk strong matter. From an observational point of view, it is
Distillation and survival of strange-quark-matter droplets in ultrarelativistic heavy-ion collisions.
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
α decay half-lives of new superheavy nuclei within a generalized liquid drop model
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
Do current astronomical observations exclude the existence of nonstrange quark stars?
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
Stability of strange star crusts and strangelets
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
Dynamical response of the nuclear “pasta” in neutron star crusts
The nuclear pasta - a novel state of matter having nucleons arranged in a variety of complex shapes - is expected to be found in the crust of neutron stars and in core-collapse supernovae at
