Velocity autocorrelation function of a Brownian particle
D. Chakraborty
In this article, we present molecular dynamics study of the velocity autocorrelation function (VACF) of a Brownian particle. We compare the results of the simulation with the exact…
Generalised Einstein Relation for Hot Brownian Motion
D. Chakraborty, M. V. Gnann, D. Rings +4
The Brownian motion of a hot nanoparticle is described by an effective Markov theory based on fluctuating hydrodynamics. Its predictions are scrutinized over a wide temperature ran…
Thermodynamics of polymer adsorption to a flexible membrane
Steffen Karalus, Wolfhard Janke, Michael Bachmann
We analyze the structural behavior of a single polymer chain grafted to an attractive, flexible surface. Our model is composed of a coarse-grained bead-and-spring polymer and a tet…
Monomer dynamics of a wormlike chain
Jakob Tómas Bullerjahn, Sebastian Sturm, Lars Wolff +1
We derive the stochastic equations of motion for a tracer that is tightly attached to a semiflexible polymer and confined or agitated by an externally controlled potential. The gen…
Hierarchies in Nucleation Transitions
Christoph Junghans, Wolfhard Janke, Michael Bachmann
We discuss the hierarchy of subphase transitions in first-order-like nucleation processes for an exemplified aggregation transition of heteropolymers. We perform an analysis of the…
Statistical Mechanics of Aggregation and Crystallization for Semiflexible Polymers
Christoph Junghans, Michael Bachmann, Wolfhard Janke
By means of multicanonical computer simulations, we investigate thermodynamic properties of the aggregation of interacting semiflexible polymers. We analyze a mesoscopic bead-stick…
