Quantum fluctuation relations in first-detection processes

A. Imparato

We derive two quantum fluctuation relations for systems undergoing repeated projective measurements. These fluctuation relations characterize the work that can be extracted from a…

First passage time distribution in underdamped harmonic oscillators

Aubin Archambault, Caroline Crauste-Thibierge, Alberto Imparato +2

We derive the distribution of the first passage time for the position of an underdamped harmonic oscillator to overcome a threshold . As the distribution…

First passage time for an underdamped harmonic oscillator and application to the power of an information engine

Aubin Archambault, Caroline Crauste-Thibierge, Alberto Imparato +2

The distribution of the first passage time for the position to overcome a threshold is calculated in an underdamped harmonic oscillator. The proof combines sever…

Information engine fueled by first-passage times

Aubin Archambault, Caroline Crauste-Thibierge, Alberto Imparato +3

Using a mechanical cantilever submitted to electrostatic feedback control, we investigate the thermodynamic properties of an information engine that extracts work from thermal fluc…

Theoretical description of effective heat transfer between two viscously coupled beads

Antoine Bérut, Alberto Imparato, Artyom Petrosyan +1

We analytically study the role of nonconservative forces, namely viscous couplings, on the statistical properties of the energy flux between two Brownian particles kept at differen…

Energy Transfer in molecular devices

M. Caraglio, A. Imparato

Protein machines often exhibit long range interplay between different sites in order to achieve their biological tasks. We investigate and characterize the non--linear energy local…

Efficiency at maximum power of motor traffic on networks

Natalia Golubeva, Alberto Imparato

We study motor traffic on Bethe networks subject to hard-core exclusion for both tightly coupled one-state machines and loosely coupled two-state machines that perform work against…

Statistical properties of the energy exchanged between two heat baths coupled by thermal fluctuations

Sergio Ciliberto, Alberto Imparato, Antoine Naert +1

We study both experimentally and theoretically the statistical properties of the energy exchanged between two electrical conductors, kept at different temperature by two different…

Maximum power operation of interacting molecular motors

Natalia Golubeva, Alberto Imparato

We study the mechanical and thermodynamic properties of different traffic models for kinesin which are relevant in biological and experimental contexts. We find that motor-motor in…

Entropy-generated power and its efficiency

Natalia Golubeva, Alberto Imparato, Massimiliano Esposito

We propose a simple model for a motor that generates mechanical motion by exploiting an entropic force arising from the topology of the underlying phase space. We show that the gen…

Efficiency at maximum power of interacting molecular machines

N. Golubeva, A. Imparato

We investigate the efficiency of systems of molecular motors operating at maximum power. We consider two models of kinesin motors on a microtubule: for both the simplified and the…

Efficiency of molecular machines with continuous phase space

N. Golubeva, A. Imparato, L. Peliti

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…

Direction dependent mechanical unfolding and Green Fluorescent Protein as a force sensor

M. Caraglio, A. Imparato, A. Pelizzola

An Ising--like model of proteins is used to investigate the mechanical unfolding of the Green Fluorescent Protein along different directions. When the protein is pulled from its en…

Pathways of mechanical unfolding of FnIII_{10}: low force intermediates

M. Caraglio, A. Imparato, A. Pelizzola

We study the mechanical unfolding pathways of the domain of fibronectin by means of an Ising--like model, using both constant force and constant velocity protocols. At…

On the surface tension of fluctuating quasi-spherical vesicles

C. Barbetta, A. Imparato, J. -B. Fournier

We calculate the stress tensor for a quasi-spherical vesicle and we thermally average it in order to obtain the actual, mechanical, surface tension of the vesicle. Both closed…
