WebAbstract Elucidating collective dynamics in crystalline systems is a common scientific question in multiple fields. In this work, by combination of high-precision numerical approach and analytical normal mode analysis, we systematically investigate the dynamical response of two-dimensional Lennard–Jones crystal as a purely classical mechanical system … WebSummary. This chapter discusses phase transitions in two-dimensional (2D) colloidal systems. In contrast to three dimensions (3D), microscopic theories of melting exist in 2D. The most well known of them was developed by Kosterlitz, Thouless, Halperin, Nelson, and Young (KTHNY theory).
