Replica Theory For Structural Glass Transition Using Density Functional Hamiltonian

Abstract

We study microscopic replica field theory of the disordered system without quenched disorder. The sharp fall of configurational entropy of a many-particle system is analyzed with the scenario of spontaneous ergodicity breaking, in which the free energy landscape of the many-particle system splits into distinct basins of local minima. The field theoretic model is formulated in terms of a density field, and a nonlocal free energy functional used in classical density functional theory (DFT) up to third order in density fluctuation
