Saddles on the potential energy landscape of a Lennard-Jones liquid
Kurt Broderix, Kamal K. Bhattacharya, Andrea Cavagna +2
By means of molecular dynamics simulations, we study the stationary points of the potential energy in a Lennard-Jones liquid, giving a purely geometric characterization of the ener…
Energy landscape of a Lennard-Jones liquid: Statistics of stationary points
Kurt Broderix, Kamal K. Bhattacharya, Andrea Cavagna +2
Molecular dynamics simulations are used to generate an ensemble of saddles of the potential energy of a Lennard-Jones liquid. Classifying all extrema by their potential energy u an…
Energy Landscape and Overlap Distribution of Binary Lennard-Jones Glasses
K. K. Bhattacharya, K. Broderix, R. Kree +1
We study the distribution of overlaps of glassy minima, taking proper care of residual symmetries of the system. Ensembles of locally stable, low lying glassy states are efficientl…
Multicanonical Methods vs. Molecular Dynamics vs. Monte Carlo: Comparison for Lennard-Jones Glasses
Kamal K. Bhattacharya, James P. Sethna
We applied a multicanonical algorithm (entropic sampling) to a two-dimensional and a three-dimensional Lennard-Jones system with quasicrystalline and glassy ground states. Focusing…
