Elastic properties of fluid mercury across the metal-nonmetal transition: Ab initio simulation study
T. Bryk, O. Bakai, A. P. Seitsonen
We report an ab initio molecular dynamics study of fluid mercury at temperature 1750 K in the range of densities 7-13.5 g/cm. Along this isothermal line we performed an analysi…
Non-Hermitian Multipole Skin Effects Challenge Localization
Jacopo Gliozzi, Federico Balducci, Taylor L. Hughes +1
