Beyond Boltzmann–Gibbs statistical mechanics in optical lattices

E Lutz, F Renzoni - Nature Physics, 2013 - nature.com
Cold atoms in dissipative optical lattices exhibit an unusual transport behaviour that cannot
be described within Boltzmann–Gibbs statistical mechanics. New theoretical tools and …

Biomolecules under mechanical force

S Kumar, MS Li - Physics Reports, 2010 - Elsevier
Recent advances in single molecule experiments have raised many challenges. These
challenges can be met by a proper understanding of the inter-and intra-molecular …

Diffusion with resetting in a logarithmic potential

S Ray, S Reuveni - The Journal of chemical physics, 2020 - pubs.aip.org
We study the effect of resetting on diffusion in a logarithmic potential. In this model, a particle
diffusing in a potential U (x)= U 0 log| x| is reset, ie, taken back to its initial position, with a …

Physics of base-pairing dynamics in DNA

M Manghi, N Destainville - Physics Reports, 2016 - Elsevier
As a key molecule of life, Deoxyribo-Nucleic Acid (DNA) is the focus of numbers of
investigations with the help of biological, chemical and physical techniques. From a physical …

Solution of the Fokker-Planck equation with a logarithmic potential

A Dechant, E Lutz, E Barkai, DA Kessler - Journal of Statistical Physics, 2011 - Springer
We investigate the diffusion of particles in an attractive one-dimensional potential that grows
logarithmically for large| x| using the Fokker-Planck equation. An eigenfunction expansion …

Colloquium: Anomalous statistics of laser-cooled atoms in dissipative optical lattices

G Afek, N Davidson, DA Kessler, E Barkai - Reviews of Modern Physics, 2023 - APS
Diffusion occurs in numerous physical systems throughout nature, drawing its generality
from the universality of the central limit theorem. Approximately a century ago it was realized …

Quantifying supercoiling-induced denaturation bubbles in DNA

J Adamcik, JH Jeon, KJ Karczewski, R Metzler… - Soft Matter, 2012 - pubs.rsc.org
In both eukaryotic and prokaryotic DNA sequences of 30–100 base-pairs rich in AT base-
pairs have been identified at which the double helix preferentially unwinds. Such DNA …

DNA denaturation bubbles: Free-energy landscape and nucleation/closure rates

F Sicard, N Destainville, M Manghi - The Journal of chemical physics, 2015 - pubs.aip.org
The issue of the nucleation and slow closure mechanisms of non-superhelical stress-
induced denaturation bubbles in DNA is tackled using coarse-grained MetaDynamics and …

Force induced DNA melting

M Santosh, PK Maiti - Journal of Physics: Condensed Matter, 2008 - iopscience.iop.org
When pulled along the axis, double-strand DNA undergoes a large conformational change
and elongates by roughly twice its initial contour length at a pulling force of about 70 pN. The …

Theoretical and experimental investigations of DNA open states

AS Shigaev, OA Ponomarev, VD Lakhno - arXiv preprint arXiv:1402.6533, 2014 - arxiv.org
Literature data on the properties of DNA open states are reviewed and analyzed. These
states are formed as a result of strong DNA fluctuations and have a great impact on a …
