The gain of free energy upon unmixing is determined via application of Markov state modeling (MSM), using an Ising model with a fixed number of up- and down-spins. MSM yields reasonable estimates of the free energies. However, a closer look reveals significant differences that point to residual non-Markovian effects. These non-Markovian effects are rather unexpected since the typical criteria to study the quality of Markovianity indicate complete Markovian behavior. We identify the sparse…

Markov models of molecular kinetics: generation and validation.

An upper bound for the approximation error made by modeling molecular dynamics with a Markov chain is described and it is shown that this error can be made arbitrarily small with surprisingly little effort.

Accounting for the kinetics in order parameter analysis: lessons from theoretical models and a disordered peptide.

Application of the methodology to theoretical models with a noisy order parameter as well as the dynamics of a disordered peptide illustrates the possibility to build accurate descriptions of molecular processes on the sole basis of order parameter time series without using any supplementary information.

Identification of slow molecular order parameters for Markov model construction.

The variational principle of conformation dynamics is used to derive an optimal way of identifying the "slow subspace" of a large set of prior order parameters - either generic internal coordinates or a user-defined set of parameters.

Markov state models from short non-equilibrium simulations—Analysis and correction of estimation bias

It is shown that the unbiased MSM estimate can be obtained even from relatively short non-equilibrium simulations in the limit of long lag times and good discretization, and how the OOM framework can be used to estimate the exact eigenvalues or relaxation time scales of the system without estimating an MSM transition matrix, which allows to practically assess the discretized quality of the MSM.

Kinetic ising model study of phase separation in binary alloys

The decomposition of binary alloys after a sudden quench below the critical temperature of unmixing is studied on a microscopic basis, using a stochastic model analog to the Kawasaki spin exchange

Describing Protein Folding Kinetics by Molecular Dynamics Simulations. 1. Theory

A rigorous formalism for the extraction of state-to-state transition functions from a Boltzmann-weighted ensemble of microcanonical molecular dynamics simulations has been developed as a way to study

Projected metastable Markov processes and their estimation with observable operator models.

It is shown that the observed dynamics of a PMM can be exactly described by an observable operator model (OOM) and derive aPMM estimator based on the OOM learning.

Progress and challenges in the automated construction of Markov state models for full protein systems.

This work demonstrates the application of a toolkit for automating the construction ofMarkov state models to the villin headpiece (HP-35 NleNle), one of the smallest and fastest folding proteins, and shows that the resulting MSM captures both the thermodynamics and kinetics of the original molecular dynamics of the system.

Estimation and uncertainty of reversible Markov models.

Methods for the maximum likelihood estimation of transition matrices from finite simulation data are discussed and a new algorithm for the estimation if reversibility with respect to a given stationary vector is desired is presented.
