Skewed superstatistical distributions from a Langevin and Fokker-Planck approach
Erik Van der Straeten, Christian Beck
The superstatistics concept is a useful statistical method to describe inhomogeneous complex systems for which a system parameter fluctuates on a large spatio-temporal scale. I…
The 3-dimensional random walk with applications to overstretched DNA and the protein titin
Erik Van der Straeten, Jan Naudts
We study the three-dimensional persistent random walk with drift. Then we develop a thermodynamic model that is based on this random walk without assuming the Boltzmann-Gibbs form…
The globule-coil transition in a mean field approach
Erik Van der Straeten, Jan Naudts
In this paper we study the unfolding transition observed in polymer stretching experiments. We use a known model and extend it with a mean-field-like interaction. Expressions for a…
A two-parameter random walk with approximate exponential probability distribution
Erik Van der Straeten, Jan Naudts
We study a non-Markovian random walk in dimension 1. It depends on two parameters eps_r and eps_l, the probabilities to go straight on when walking to the right, respectively to th…
A one-dimensional model for theoretical analysis of single molecule experiments
Erik Van der Straeten, Jan Naudts
In this paper we compare two polymer stretching experiments. The outcome of both experiments is a force-extension relation. We use a one-dimensional model to show that in general t…
The quantum double well anharmonic oscillator in an external field
Erik Van der Straeten, Jan Naudts
The aim of this paper is twofold. First of all, we study the behaviour of the lowest eigenvalues of the quantum anharmonic oscillator under influence of an external field. We try t…
