Area of Science:

  • Condensed matter physics
  • Materials science
  • Computational physics

Background:

  • Understanding material properties under extreme conditions is crucial.
  • Xenon's phase transitions provide insights into noble gas behavior.
  • Previous studies lacked detailed phonon spectrum analysis for fcc xenon under pressure.

Purpose of the Study:

  • To calculate the phonon spectrum of face-centered cubic (fcc) xenon under pressure.
  • To determine the thermodynamic properties and phase transition pressures.
  • To investigate the dynamical stability of xenon's crystal structures.

Main Methods:

  • Density-functional perturbation theory (DFPT) was employed.
  • The quasiharmonic approximation (QHA) was used for thermodynamic calculations.
  • Phonon spectra were computed for various pressures.

Main Results:

  • Thermodynamic properties align well with experimental data at ambient pressure.
  • The face-centered cubic (fcc) to hexagonal close-packed (hcp) phase transition is predicted at 5 GPa.
  • The fcc phase remains dynamically stable up to 100 GPa, with softening at X and L points thereafter.

Conclusions:

  • The fcc phase of xenon exhibits high dynamical stability.
  • Sluggish fcc-hcp transition kinetics are attributed to minimal phase energy differences and fcc stability.
  • Computational methods accurately predict xenon's behavior under pressure.
