Statistics of two-dimensional random walks, the « cyclic sieving phenomenon » and the Hofstadter model

Stefan Mashkevich 1, 2 Stéphane Ouvry 3 Alexios Polychronakos 4 Journal of Physics A: Mathematical and Theoretical, IOP Publishing, 2015, 48, pp.405001 We focus on the algebraic area probability distribution of planar random walks on a square lattice with $m_1$, $m_2$, $l_1$ and $l_2$ steps right, left, up and down. We aim, in particular, at […]

Statistics of the longest interval in renewal processes

Claude Godreche 1 Satya N. Majumdar 2 Gregory Schehr 2 Journal of Statistical Mechanics: Theory and Experiment, IOP Science, 2015, pp.P03014 We consider renewal processes where events, which can for instance be the zero crossings of a stochastic process, occur at random epochs of time. The intervals of time between events, $\tau_{1},\tau_{2},…$, are independent and

Statistical physics methods provide the exact solution to a long-standing problem of genetics

Areejit Samal 1, 2, 3 Olivier C. Martin 4 Physical Review Letters, American Physical Society, 2015, 114, pp.238101 Analytic and computational methods developed within statistical physics have found applications in numerous disciplines. In this letter, we use such methods to solve a long-standing problem in statistical genetics. The problem, posed by Haldane and Waddington [J.B.S.

Screening like-charges in one-dimensional Coulomb systems: Exact results

Gabriel Tellez 1 Emmanuel Trizac 2 Physical Review E : Statistical, Nonlinear, and Soft Matter Physics, American Physical Society, 2015, 92, pp.042134 The possibility that like-charges can attract each other under the mediation of mobile counterions is by now well documented experimentally, numerically, and analytically. Yet, obtaining exact results is in general impossible, or restricted

Relaxation of Loaded ESCRT-III Spiral Springs Drives Membrane Deformation

Nicolas Chiaruttini 1 Lorena Redondo-Morata 2 Adai Colom 1, 2, 3 Frédéric Humbert 1 Martin Lenz 4, * Simon Scheuring 2, * Aurélien Roux 1, 3, * Cell, Elsevier, 2015, <10.1016/j.cell.2015.10.017> 13 ESCRT-III is required for lipid membrane remodeling in many cellular processes, from abscission 14 to viral budding and multi-vesicular body biogenesis. However, how
