Counter-propagating dual-trap optical tweezers based on linear momentum conservation
Marco Ribezzi Crivellari, Josep M. Huguet, Felix Ritort
We present a dual-trap optical tweezers setup which directly measures forces using linear momentum conservation. The setup uses a counter-propagating geometry, which allows momentu…
Force Spectroscopy with Dual-Trap Optical Tweezers: Molecular Stiffness Measurements and Coupled Fluctuations Analysis
Marco Ribezzi Crivellari, Felix Ritort
Dual trap optical tweezers are often used in high-resolution measurements in single-molecule biophysics. Such measurements can be hindered by the presence of extraneous noise sourc…
Experimental free energy measurements of kinetic molecular states using fluctuation theorems
Anna Alemany, Alessandro Mossa, Ivan Junier +1
Recent advances in non-equilibrium statistical mechanics and single molecule technologies make it possible to extract free energy differences from irreversible work measurements in…
A fluctuation relation for weakly ergodic aging systems
A. Crisanti, M. Picco, F. Ritort
A fluctuation relation for aging systems is introduced, and verified by extensive numerical simulations. It is based on the hypothesis of partial equilibration over phase space reg…
