Sensitivity of the thermodynamics of two-dimensional systems towards the topological classes of their surfaces
Oleg A. Vasilyev, Anna Maciolek, S. Dietrich
Using Monte Carlo simulations we study the two-dimensional Ising model on triangular, square, and hexagonal lattices with various topologies. We focus on the behavior of the magnet…
Critical Casimir Effect: Exact Results
D. M. Dantchev, S. Dietrich
In any medium there are fluctuations due to temperature or due to the quantum nature of its constituents. If a material body is immersed into such a medium, its shape and the prope…
Fluctuations of the critical Casimir force
Markus Gross, Andrea Gambassi, S. Dietrich
The critical Casimir force (CCF) arises from confining fluctuations in a critical fluid and thus it is a fluctuating quantity itself. While the mean CCF is universal, its (static)…
Finite-size corrections for the static structure factor of a liquid slab with open boundaries
Felix Höfling, Siegfried Dietrich
The presence of a confining boundary can modify the local structure of a liquid markedly. In addition, small samples of finite size are known to exhibit systematic deviations of th…
Effective Pair Interaction of Patchy Particles in Critical Fluids
Nima Farahmand Bafi, Piotr Nowakowski, Siegfried Dietrich
We study the critical Casimir interaction between two spherical colloids immersed in a binary liquid mixture close to its critical demixing point. The surface of each colloid prefe…
Critical Casimir interaction between colloidal Janus-type particles in two spatial dimensions
Alessio Squarcini, Anna Maciołek, Erich Eisenriegler +1
We study colloidal particles with chemically inhomogeneous surfaces suspended in a critical binary liquid mixture. The inhomogeneous particle surface is composed of patches with al…
Dynamics of the critical Casimir force for a conserved order parameter after a critical quench
Markus Gross, Christian M. Rohwer, S. Dietrich
Fluctuation-induced forces occur generically when long-ranged correlations (e.g., in fluids) are confined by external bodies. In classical systems, such correlations require specif…

Christian M. Rohwer, Alessio Squarcini, Oleg Vasilyev +2
In a recent study [Phys. Rev. E \textbf{94}, 022103 (2016)] it has been shown that, for a fluid film subject to critical adsorption, the resulting critical Casimir force (CCF) may…

Alessandro Magazzù, Agnese Callegari, Juan Pablo Staforelli +3
Critical Casimir forces can play an important role for applications in nano-science and nanotechnology, owing to their piconewton strength, nanometric action range, fine tunability…

Markus Gross, Andrea Gambassi, S. Dietrich
Using analytic and numerical approaches, we study the spatio-temporal evolution of a conserved order parameter of a fluid in film geometry, following an instantaneous quench to the…

The dynamic and static critical behavior of five binary Lennard-Jones liquid mixtures, close to their continuous demixing points (belonging to the so-called model H' dynamic univer…

An exact statistical mechanical derivation is given of the critical Casimir interactions between two defects in a planar lattice-gas Ising model. Each defect is a group of nearest-…
