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…
Stationary and transient Fluctuation Theorems for effective heat flux between hydrodynamically coupled particles in optical traps
A Bérut, A Imparato, A Petrosyan +1
We experimentally study the statistical properties of the energy fluxes between two trapped Brownian particles, interacting through dissipative hydrodynamic coupling, submitted to…
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…
