Singular diffusion and criticality in a confined sandpile
R. S. Pires, A. A. Moreira, H. A. Carmona +1
We investigate the behavior of a two-state sandpile model subjected to a confining potential in one and two dimensions. From the microdynamical description of this simple model wit…
Electrostatic Interactions in Strongly-Coupled Soft Matter
Ali Naji, Swetlana Jungblut, Andre G. Moreira +1
Charged soft-matter systems--such as colloidal dispersions and charged polymers--are dominated by attractive forces between constituent like-charged particles when neutralizing cou…
Global Stationary Phase and the Sign Problem
A G Moreira, S A Baeurle, G H Fredrickson
We present a computational strategy for reducing the sign problem in the evaluation of high dimensional integrals with non-positive definite weights. The method involves stochastic…
Virial expansion for charged colloids and electrolytes
Andre G Moreira, Roland R Netz
Using a field-theoretic approach, we derive the first few coefficients of the exact low-density (``virial'') expansion of a binary mixture of positively and negatively charged hard…
Counterions at charge-modulated substrates
Andre G Moreira, Roland R Netz
We consider counterions in the presence of a single planar surface with a spatially inhomogeneous charge distribution using Monte-Carlo simulations and strong-coupling theory. For…
Polyelectrolyte-colloid complexes: polarizability and effective interaction
J. Dzubiella, A. G. Moreira, P. A. Pincus
We theoretically study the polarizability and the interactions of neutral complexes consisting of a semi-flexible polyelectrolyte adsorbed onto an oppositely charged spherical coll…
