It is shown that, as the confinement of the particle increases, the stationary probability distribution of a Brownian particle confined within a harmonic potential becomes non-Boltzmann, featuring a transition from a Gaussian distribution to a heavy-tailed distribution.
Heat flux and entropy produced by thermal fluctuations.
An experimental and theoretical analysis of the energy exchanged between two conductors kept at different temperature and coupled by the electric thermal noise sets strong constraints on the energy exchanges between coupled nanosystems held at different temperatures.
Statistical properties of the energy exchanged between two heat baths coupled by thermal fluctuations
We study both experimentally and theoretically the statistical properties of the energy exchanged between two electrical conductors, kept at different temperatures by two different heat reservoirs,…
Ising-like model for protein mechanical unfolding.
The mechanical unfolding of proteins is studied by extending the Wako-Saitô-Muñoz-Eaton model, and the free energy landscape of the PIN1 as a function of the molecule length is computed.

This work studies the elastic response of bilayer membranes with fixed projected area to both the stretching and shape deformations and introduces a simple theory which relates the two quantities and successfully applies it to the data obtained with computer simulations.
Changing the mechanical unfolding pathway of FnIII10 by tuning the pulling strength.
Efficiency of molecular machines with continuous phase space
We consider a molecular machine described as a Brownian particle diffusing in a tilted periodic potential. We evaluate the absorbed and released power of the machine as a function of the applied…
Protein mechanical unfolding: a model with binary variables.
The extended Jarzynski equality is exploited to investigate the possibility of reconstructing the free energy landscape of proteins with pulling experiments, and the kinetic parameters characterizing the protein unfolding agree nicely with experimental results, when these are available.
Charging assisted by thermalization
A system in thermal equilibrium with a bath will generally be in an athermal state, if the system-bath coupling is strong. In some cases, it will be possible to extract work from that athermal state,…
Theoretical description of effective heat transfer between two viscously coupled beads.
An energy flow is identified that satisfies a fluctuation theorem both in the stationary and in transient states and which involves the energy flux alone for the specific case of a linear nonconservative interaction.
