Measurement of work in single-molecule pulling experiments
(AIP Publishing, 2009)
A main goal of single-molecule experiments is to evaluate equilibrium free energy differences by applying fluctuation relations to repeated work measurements along irreversible processes. We quantify ...
Dynamic force spectroscopy of DNA hairpins: II. Irreversibility and dissipation
(IOP Publishing, 2009)
We investigate irreversibility and dissipation in single molecules that cooperatively fold/unfold in a two-state manner under the action of mechanical force. We apply path thermodynamics to derive ...
Dynamic force spectroscopy of DNA hairpins: I. Force kinetics and free energy landscapes
(IOP Publishing, 2009)
We investigate the thermodynamics and kinetics of DNA hairpins that fold/unfold under the action of applied mechanical force. We introduce the concept of the molecular free energy landscape and derive ...
Work distributions in the T = 0 random field Ising model
(American Physical Society, 2008)
We perform a numerical study of the three-dimensional random-field Ising model at T= 0. We compare work distributions along metastable trajectories obtained with the single-spin flip dynamics with the ...
2P-111 Stochastic resonance in DNA hairpins(The 46th Annual Meeting of the Biophysical Society of Japan)
(The Biophysical Society of Japan, 2008)
Statistical properties of metastable intermediates in DNA unzipping
(American Physical Society, 2009)
We unzip DNA molecules using optical tweezers and determine the sizes of the cooperatively unzipping and zipping regions separating consecutive metastable intermediates along the unzipping pathway. Sizes ...
