Critical Casimir forces in soft matter

A Gambassi, S Dietrich - Soft Matter, 2024 - pubs.rsc.org
We review recent advances in the theoretical, numerical, and experimental studies of critical
Casimir forces in soft matter, with particular emphasis on their relevance for the structures of …

Momentum tunnelling between nanoscale liquid flows

B Coquinot, AT Bui, D Toquer, A Michaelides… - Nature …, 2025 - nature.com
The world of nanoscales in fluidics is the frontier where the continuum of fluid mechanics
meets the atomic, and even quantum, nature of matter. While water dynamics remains …

Nonequilibrium critical Casimir effect in binary fluids

A Furukawa, A Gambassi, S Dietrich, H Tanaka - Physical review letters, 2013 - APS
Colloids immersed in a critical binary liquid mixture are subject to critical Casimir forces
(CCFs) because they confine its concentration fluctuations and influence the latter via …

Transient fluctuation-induced forces in driven electrolytes after an electric field quench

S Mahdisoltani, R Golestanian - New Journal of Physics, 2021 - iopscience.iop.org
Understanding how electrolyte solutions behave out of thermal equilibrium is a long-
standing endeavor in many areas of chemistry and biology. Although mean-field theories …

Stresses in non-equilibrium fluids: Exact formulation and coarse-grained theory

M Krüger, A Solon, V Démery, CM Rohwer… - The Journal of chemical …, 2018 - pubs.aip.org
Starting from the stochastic equation for the density operator, we formulate the exact
(instantaneous) stress tensor for interacting Brownian particles and show that its average …

Transient Casimir forces from quenches in thermal and active matter

CM Rohwer, M Kardar, M Krüger - Physical review letters, 2017 - APS
We compute fluctuation-induced (Casimir) forces for classical systems after a temperature
quench. Using a generic coarse-grained model for fluctuations of a conserved density, we …

Tracer particle in a confined correlated medium: an adiabatic elimination method

D Venturelli, M Gross - Journal of Statistical Mechanics: Theory …, 2022 - iopscience.iop.org
We present a simple and systematic procedure to determine the effective dynamics of a
Brownian particle coupled to a rapidly fluctuating correlated medium, modeled as a scalar …

Relaxation of the thermal Casimir force between net neutral plates containing Brownian charges

DS Dean, R Podgornik - Physical Review E, 2014 - APS
We investigate the dynamics of thermal Casimir interactions between plates described
within a living conductor model, with embedded mobile anions and cations, whose density …

Nonequilibrium forces following quenches in active and thermal matter

CM Rohwer, A Solon, M Kardar, M Krüger - Physical Review E, 2018 - APS
Nonequilibrium systems with conserved quantities like density or momentum are known to
exhibit long-ranged correlations. This, in turn, leads to long-ranged fluctuation-induced …

Anisotropic particles near surfaces: Propulsion force and friction

B Müller, M Krüger - Physical Review A, 2016 - APS
We theoretically study the phenomenon of propulsion through Casimir forces in thermal
nonequilibrium. Using fluctuational electrodynamics, we derive a formula for the propulsion …
