摘要
We numerically elucidate the microscopic mechanisms controlling the relaxation dynamics of a three-dimensional lattice glass model that has static properties compatible with the approach to a random first-order transition. At low temperatures, the relaxation is triggered by a small population of particles with low-energy barriers forming mobile clusters. These emerging quasiparticles act as facilitating defects responsible for the spatially heterogeneous dynamics of the system, whose characteristic length scales remain strongly coupled to thermodynamic fluctuations. We compare our findings both with existing theoretical models and atomistic simulations of glass formers.Received 16 August 2023Accepted 20 December 2023DOI:https://doi.org/10.1103/PhysRevLett.132.067101© 2024 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasGlass transitionPhysical SystemsEquilibrium lattice modelsGlassesTechniquesMonte Carlo methodsStatistical Physics & ThermodynamicsPolymers & Soft Matter
