On the kinetics that moves Myosin V

Christian Maes, Winny O'Kelly de Galway

Molecular motor proteins such as Myosin V, Dynein or Kinesin are no ratchets, at least not with a flashing asymmetric potential; the crucial asymmetry is in the dynamical activity.…

Friction and noise for a probe in a nonequilibrium fluid

Christian Maes, Stefano Steffenoni

We investigate the fluctuation dynamics of a probe around a deterministic motion induced by interactions with driven particles. The latter constitute the nonequilibrium medium in w…

Apparent first-order wetting and anomalous scaling in the two-dimensional Ising model

X. T. Wu, D. B. Abraham, J. O. Indekeu

The global phase diagram of wetting in the two-dimensional (2d) Ising model is obtained through exact calculation of the surface excess free energy. Besides a surface field for ind…

Frenetic aspects of second order response

Urna Basu, Matthias Krüger, Alexandre Lazarescu +1

Starting from second order around thermal equilibrium, the response of a statistical mechanical system to an external stimulus is not only governed by dissipation and depends expli…

Self-organised criticality in stochastic sandpiles: Connection to directed percolation

U. Basu, P. K. Mohanty

We introduce a stochastic sandpile model where finite drive and dissipation are coupled to the activity field. The absorbing phase transition here, as expected, belongs to the dire…

Revisiting the Glansdorff-Prigogine criterion for stability within irreversible thermodynamics

Christian Maes, Karel Netocny

Glansdorff and Prigogine (1970) proposed a decomposition of the entropy production rate, which today is mostly known for Markov processes as the Hatano-Sasa approach. Their context…

Temperature gradients in equilibrium: small microcanonical systems in an external field

Alberto Salazar, Hernán Larralde, Francois Leyvraz

We consider the statistical mechanics of a small gaseous system subject to a constant external field. As is well known, in the canonical ensemble the system i) obeys a barometric f…

Rotational dynamics of entangled polymers

Jean-Charles Walter, Michiel Laleman, Marco Baiesi +1

Some recent results on the rotational dynamics of polymers are reviewed and extended. We focus here on the relaxation of a polymer, either flexible or semiflexible, initially wrapp…

Scenario for delocalization in translation invariant systems

Wojciech De Roeck, Francois Huveneers

We investigate the possibility of Many-Body Localization in translation invariant Hamiltonian systems, which was recently brought up by several authors. A key feature of Many-Body…

Models of DNA denaturation dynamics: universal properties

Marco Baiesi, Enrico Carlon

We briefly review some of the models used to describe DNA denaturation dynamics, focusing on the value of the dynamical exponent , which governs the scaling of the characteristi…

Hyperscaling above the upper critical dimension

Bertrand Berche, Ralph Kenna, Jean-Charles Walter

Above the upper critical dimension, the breakdown of hyperscaling is associated with dangerous irrelevant variables in the renormalization group formalism at least for systems with…

Maximum work extraction and implementation costs for non-equilibrium Maxwell's demons

Henrik Sandberg, Jean-Charles Delvenne, Nigel J. Newton +1

In this theoretical study, we determine the maximum amount of work extractable in finite time by a demon performing continuous measurements on a quadratic Hamiltonian system subjec…
