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…
Negative fluctuation-dissipation ratios in the backgammon model
A. Garriga, I. Pagonabarraga, F. Ritort
We analyze fluctuation-dissipation relations in the Backgammon model: a system that displays glassy behavior at zero temperature due to the existence of entropy barriers. We study…
Force unfolding kinetics of RNA using optical tweezers. II. Modeling experiments
M. Manosas, J. -D. Wen, P. T. X. Li +4
By exerting mechanical force it is possible to unfold/refold RNA molecules one at a time. In a small range of forces, an RNA molecule can hop between the folded and the unfolded st…
Work and heat fluctuations in two-state systems: a trajectory thermodynamics formalism
F. Ritort
Two-state models provide phenomenological descriptions of many different systems, ranging from physics to chemistry and biology. We investigate work fluctuations in an ensemble of…
Work fluctuations, transient violations of the second law and free-energy recovery methods: Perspectives in Theory and Experiments
F. Ritort
In this report I discuss fluctuation theorems and transient violations of the second law of thermodynamics in small systems. Special emphasis is placed on free-energy recovery meth…
Damage spreading transition in glasses: a probe for the ruggedness of the configurational landscape
M. Heerema, F. Ritort
We consider damage spreading transitions in the framework of mode-coupling theory. This theory describes relaxation processes in glasses in the mean-field approximation which are k…
Solvable dynamics in a system of interacting random tops
Felix Ritort
In this letter a new solvable model of synchronization dynamics is introduced. It consists of a system of long range interacting tops with random precession frequencies. The model…
Evidence of a Critical time in Constrained Kinetic Ising models
E. Follana, F. Ritort
We study the relaxational dynamics of the one-spin facilitated Ising model introduced by Fredrickson and Andersen. We show the existence of a critical time which separates an initi…
