The q-exponential family in statistical physics
Jan Naudts
The notion of generalised exponential family is considered in the restricted context of nonextensive statistical physics. Examples are given of models belonging to this family. In…
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…
Generalised thermostatistics using hyperensembles
Jan Naudts
The hyperensembles, introduced by Crooks in a context of non-equilibrium statistical physics, are considered here as a tool for systems in equilibrium. Simple examples like the ide…
Residual entropy in a model for the unfolding of single polymer chains
Erik Van der Straeten, Jan Naudts
We study the unfolding of a single polymer chain due to an external force. We use a simplified model which allows to perform all calculations in closed form without assuming a Bolt…
