Title: Correlation effects in partially ionized mass asymmetric electron-hole plasmas

Abstract

The effects of strong Coulomb correlations in dense three-dimensional electron-hole plasmas are studied by means of unbiased direct path integral Monte Carlo simulations. The formation and dissociation of bound states, such as excitons and biexcitons, is analyzed and the density-temperature region of their appearance is identified. At high density, the Mott transition to the fully ionized metallic state (electron-hole liquid) is detected. Particular attention is paid to the influence of the hole to electron mass ratio M on the properties of the plasma. Above a critical value of about M=80 formation of a hole Coulomb crystal was recently verified [Bonitz et al., Phys. Rev. Lett. 95, 235006 (2005)] which is supported by additional results. Results are related to the excitonic phase diagram of intermediate valent Tm[Se,Te], where large values of M have been observed experimentally.

  • The nonideal collective and plasma screening effects on nonrelativistic electron-atom bremsstrahlung process are investigated in partially ionized hydrogen plasmas. The effective pseudopotential model taking into account the screening and collective effects is applied to describe the interaction potential in nonideal plasmas. The electron-atom bremsstrahlung radiation cross section is obtained as a function of the nonideality plasma parameter, Debye length, projectile energy, and radiation photon energy. The results show that the collective and screening effects reduce the electron-atom bremsstrahlung radiation cross section in nonideal plasmas, especially, for the soft radiation region. It is also found that the atomic correlation effect suppressesmore » the bremsstrahlung radiation cross section and is decreased with the increase in the nonideality plasma parameter.« less
  • The quantum effects on the formation of the negative hydrogen ion (H{sup -}) by the polarization electron capture process are investigated in partially ionized dense hydrogen plasmas. It is shown that the quantum effect strongly suppresses the electron capture radius as well as the cross section for the formation of the negative hydrogen ion. In addition, it has been found that the electron capture position is receded from the center of the projectile in decreasing the quantum effect of the plasma.
  • The enhancement of the fusion reaction rate in high-density two-component plasmas that consist of deuterium (D) and high-{ital Z} material such as carbon (C) or titanium (Ti) has been investigated theoretically. Ion-ion correlation in high-density two-component plasmas is described by a hypernetted-chain (HNC) equation including Coulomb potential of bound electrons. To take into account the effects of bound electrons, we calculate the degree of ionization of atoms consistently with HNC equations by using the Thomas-Fermi model. The results show that the fusion reaction rate of the D-D interaction is enhanced by a factor from 2 to 4 because the strongmore » screening by the surrounding high-{ital Z} ions reduces an effective potential between two colliding deuteriums, and then the degree of ionization of high-{ital Z} materials is found to be important to determine the enhancement factors.« less
  • The renormalization plasma screening effects on the elastic electron-atom collision are investigated in partially ionized dense hydrogen plasmas using the eikonal method. It is found that the renormalization plasma screening suppresses the eikonal phase shift and cross section for the elastic electron-atom collision in partially ionized plasmas. It is also found that the renormalization plasma screening effect on the elastic electron-atom collision process increases with an increasing impact parameter. In addition, it is found that the maximum position of the differential cross section is receded from the center of the atom with an increase of the Debye length.
