Trajectory reweighting for non-equilibrium steady states
Patrick B. Warren, Rosalind J. Allen
Modern methods for sampling rugged landscapes in state space mainly rely on knowledge of the relative probabilities of microstates, which is given by the Boltzmann factor for equil…
Perspective: Dissipative Particle Dynamics
Pep Español, Patrick B Warren
Dissipative particle dynamics (DPD) belongs to a class of models and computational algorithms developed to address mesoscale problems in complex fluids and soft matter in general.…
Gibbs, Boltzmann, and negative temperatures
Daan Frenkel, Patrick B Warren
In a recent paper, Dunkel and Hilbert [Nature Physics 10, 67-72 (2014)] use an entropy definition due to Gibbs to provide a 'consistent thermostatistics' which forbids negative abs…
Malliavin weight sampling: a practical guide
Patrick B. Warren, Rosalind J. Allen
Malliavin weight sampling (MWS) is a stochastic calculus technique for computing the derivatives of averaged system properties with respect to parameters in stochastic simulations,…
No-go theorem in many body dissipative particle dynamics
Patrick B. Warren
Many body dissipative particle dynamics (MDPD) is a particle-based simulation method in which the interaction potential is a sum of self energies depending on locally-sampled densi…
Phase behaviour and the random phase approximation for ultrasoft restricted primitive models
Patrick B. Warren, Andrew J. Masters
Phase separation of the ultrasoft restricted primitive model (URPM) with Gaussian charges is re-investigated in the random phase approximation (RPA)---the 'Level A' approximation d…
The shape of a ponytail and the statistical physics of hair fiber bundles
Raymond E. Goldstein, Patrick B. Warren, Robin C. Ball
A general continuum theory for the distribution of hairs in a bundle is developed, treating individual fibers as elastic filaments with random intrinsic curvatures. Applying this f…
Statistical mixing and aggregation in Feller diffusion
Celia Anteneodo, Silvio M. Duarte Queiros
We consider Feller mean-reverting square-root diffusion, which has been applied to model a wide variety of processes with linearly state-dependent diffusion, such as stochastic vol…
On a comparative study between dependence scales determined by linear and non-linear measures
Silvio M. Duarte Queiros
In this manuscript we present a comparative study about the determination of the relaxation (\textit{i.e.}, independence) time scales obtained from the correlation function, the mu…
On the role of ergodicity and mixing in the central limit theorem for Casati-Prosen triangle map variables
Silvio M. Duarte Queiros
In this manuscript we analyse the behaviour of the probability density function of the sum of deterministic variables generated from the triangle map of Casati-Prosen. For the…
Late stage kinetics for various wicking and spreading problems
Patrick B. Warren
The kinetics of spreading of a liquid drop in a wedge or V-shaped groove, in a network of such grooves, and on a hydrophilic strip, is re-examined. The length of a droplet of volum…
Vapour-liquid coexistence in many-body dissipative particle dynamics
P. B. Warren
Many-body dissipative particle dynamics is constructed to exhibit vapour-liquid coexistence, with a sharp interface, and a vapour phase of vanishingly small density. In this form,…
Hydrodynamic bubble coarsening in off-critical vapour-liquid phase separation
Patrick B. Warren
Late-stage coarsening in off-critical vapour-liquid phase separation is re-examined. In the limit of bubbles of vapour distributed throughout a continuous liquid phase, it is argue…
Kinetic theory for dissipative particle dynamics: the importance of collisions
A. J. Masters, P. B. Warren
Kinetic theory of dissipative particle dynamics is developed in terms of a Boltzmann pair collision theory. The kinetic transport coefficients are computed from explicit collision…
Fluid-fluid phase separation in hard spheres with a bimodal size distribution
P. B. Warren
The effect of polydispersity on the phase behaviour of hard spheres is examined using a moment projection method. It is found that the Boublik-Mansoori-Carnahan-Starling-Leland equ…
