Breaking stress of Coulomb crystals in the neutron star crust

It is generally accepted that the Coulomb crystal model can be used to describe matter in neutron star crust. In [1] we study properties of deformed crystals and how their stability depends on polarization electron background; breaking stress crust $\sigma_{\max}$ at zero temperature was calculated based analysis electrostatic energy phonon spectrum crystal. this paper, I briefly discuss influence zero-point thermal contributions $\sigma_{\max}$.
