The mechanics and statistics of active matter

S Ramaswamy - Annu. Rev. Condens. Matter Phys., 2010 - annualreviews.org
Active particles contain internal degrees of freedom with the ability to take in and dissipate
energy and, in the process, execute systematic movement. Examples include all living …

Active matter

S Ramaswamy - Journal of Statistical Mechanics: Theory and …, 2017 - iopscience.iop.org
The study of systems with sustained energy uptake and dissipation at the scale of the
constituent particles is an area of central interest in nonequilibrium statistical physics …

Origins and diagnostics of the nonequilibrium character of active systems

LP Dadhichi, A Maitra… - Journal of Statistical …, 2018 - iopscience.iop.org
We present in detail a Langevin formalism for constructing stochastic dynamical equations

Collective mechanics of small migrating cell groups

W Shi, S Gupta, C Copos, A Mogilner - Seminars in Cell & Developmental …, 2025 - Elsevier
Migration of adhesive cell groups is a fundamental part of wound healing, development and
carcinogenesis. Intense research has been conducted on mechanisms of collective …

Cell clusters adopt a collective amoeboid mode of migration in confined nonadhesive environments

DL Pagès, E Dornier, J De Seze, E Gontran… - Science …, 2022 - science.org

We propose a framework for describing the dynamics associated with the adsorption of
small molecules to liquid–vapor interfaces using an intermediate resolution between …

Short-time expansion of one-dimensional Fokker-Planck equations with heterogeneous diffusion

T Dupont, S Giordano, F Cleri, R Blossey - Physical Review E, 2024 - APS
We formulate a short-time expansion for one-dimensional Fokker-Planck equations with
spatially dependent diffusion coefficients, derived from stochastic processes with Gaussian …

Soft inclusion in a confined fluctuating active gel

A Singh Vishen, JF Rupprecht, GV Shivashankar… - Physical Review E, 2018 - APS
We study stochastic dynamics of a point and extended inclusion within a one-dimensional
confined active viscoelastic gel. We show that the dynamics of a point inclusion can be …
