Abstract
The molecular dynamics method is employed to study the thermodynamic parameters of a two-dimensional Lennard-Jones crystal at negative pressures. The calculations are performed for five isotherms. The lowest temperature approaches absolute zero, and the highest temperature is 35% lower than that of the triple point. The limits of attainable tension and the thermodynamic stability of the crystal as well as the lifetimes of the ultimately strained states and the relaxation times in a disordered crystal are estimated. The thermal characteristics of disordering in the crystalline state are revealed and investigated.
