Nonequilibrium Dynamics of the Helix-Coil Transition in Polyalanine
Maximilian Conradi, Henrik Christiansen, Suman Majumder +2
In this work, the nonequilibrium pathways of the collapse of the helix-forming biopolymer polyalanine are investigated. To this end, the full time evolution of the helix-coil trans…
Influence of Thermostats on the Dynamics of the Helix-Coil Transition
Maximilian Conradi, Henrik Christiansen, Suman Majumder +2
We present results from all-atom molecular dynamics simulations for the nonequilibrium dynamics of the collapse and helix-coil transition in polyalanine. In particular, we compare…
Finite-Size Effects in Aging can be Interpreted as Sub-Aging
Henrik Christiansen, Suman Majumder, Wolfhard Janke +1
Systems brought out of equilibrium through a rapid quench from a disordered initial state into an ordered phase undergo physical aging in the form of phase-ordering kinetics, with…
Non-universality of aging during phase separation of the two-dimensional long-range Ising model
Fabio Müller, Henrik Christiansen, Wolfhard Janke
We investigate the aging properties of phase-separation kinetics following quenches from to a finite temperature below of the paradigmatic two-dimensional conserve…
Temperature and Solvent Viscosity Tune the Intermediates During the Collapse of a Polymer
Suman Majumder, Henrik Christiansen, Wolfhard Janke
Dynamics of a polymer chain in solution gets significantly affected by the temperature and the frictional forces arising due to solvent viscosity. Here, using an explicit solvent f…
Aging following a zero-temperature quench in the Ising model
Denis Gessert, Henrik Christiansen, Wolfhard Janke
Aging in phase-ordering kinetics of the Ising model following a quench from infinite to zero temperature is studied by means of Monte Carlo simulations. In this model the two…
Superdiffusion-like behavior in zero-temperature coarsening of the Ising model
Denis Gessert, Henrik Christiansen, Wolfhard Janke
One key aspect of coarsening following a quench below the critical temperature is domain growth. For the non-conserved Ising model a power-law growth of domains of like spins with…

Fabio Müller, Henrik Christiansen, Stefan Schnabel +1
We present a fast, hierarchical, and adaptive algorithm for Metropolis Monte Carlo simulations of systems with long-range interactions that reproduces the dynamics of a standard im…

Henrik Christiansen, Suman Majumder, Wolfhard Janke
We investigate the nonequilibrium dynamics following a quench to zero temperature of the non-conserved Ising model with power-law decaying long-range interactions $\propto 1/r^{d+σ…
Simulating Met-Enkephalin With Population Annealing Molecular Dynamics
Henrik Christiansen, Martin Weigel, Wolfhard Janke
Met-enkephalin, one of the smallest opiate peptides and an important neurotransmitter, is a widely used benchmarking problem in the field of molecular simulation. Through its range…
Understanding nonequilibrium scaling laws governing collapse of a polymer
Suman Majumder, Henrik Christiansen, Wolfhard Janke
Recent emerging interest in experiments of single-polymer dynamics urge computational physicists to revive their understandings, particularly in the nonequilibrium context. Here we…
Aging in the long-range Ising model
Henrik Christiansen, Suman Majumder, Malte Henkel +1
The current understanding of aging phenomena is mainly confined to the study of systems with short-ranged interactions. Little is known about the aging of long-ranged systems. Here…
Dissipative Dynamics of a Single Polymer in Solution: A Lowe-Andersen Approach
Suman Majumder, Henrik Christiansen, Wolfhard Janke
We study the equilibrium dynamics of a single polymer chain under good solvent condition. Special emphasis is laid on varying the drag force experienced by the chain while it moves…
