Variational evolution of one-dimensional Lennard-Jones systems
Scope of this paper is twofold: on one hand we continue the study of LennardJones systems from the standpoint of variational principles, on the other hand these allow to provide a non-trivial example within the theory of minimizing movements. In a one-dimensional static setting, Lennard-Jones systems have been shown to be equivalent to energies of Fracture Mechanics using the notion of equivale...
متن کاملInteracting Solitary Waves in a Damped Driven Lennard-jones Chain
It is shown analytically that pulse solitary waves in a chain with Lermard-Jones type nearest neighbor interaction are strongly localized and marginally stable in the high energy limit. In a damped and periodically driven chain we obtain numerically families of states whose behavior is similar to that of equally many oscillators. We observe a period doubling sequence in a one-solitary wave fami...
متن کاملA Study of the Thermal Properties of a One Dimensional Lennard-Jones System
In this study, the behavior of a one dimensional (1D) Lennard-Jones (LJ) system is simulated. As part of this research, a special purpose computer program was designed, coded, and tested. In both the model and the program calculations, energy and momentum are conserved. The modeling assumes constant pressure throughout each simulation, although several different pressures are modeled. The simul...
متن کاملDynamics of vacancies in two-dimensional Lennard-Jones crystals.
Vacancies represent an important class of crystallographic defects, and their behaviors can be strongly coupled with relevant material properties. In this work, we study the dynamics of generic n-point vacancies in two-dimensional Lennard-Jones crystals in several thermodynamic states. Simulations reveal the spectrum of distinct, size-dependent vacancy dynamics, including the nonmonotonously va...
متن کاملDislocation mobility in two-dimensional Lennard–Jones material
In seeking to understand at a microscopic level the response of dislocations to stress, we have undertaken to study as completely as possible the simplest case: a single dislocation in a two-dimensional crystal. The intention is that results from this study will be used as input parameters in larger length scale simulations involving many defects. We present atomistic simulations of defect moti...
