Spherically averaged versus angle-dependent interactions in quadrupolar fluids
Bortolo Matteo Mognetti, Martin Oettel, Leonid Yelash +3
Employing simplified models in computer simulation is on the one hand often enforced by computer time limitations but on the other hand it offers insights into the molecular proper…
Third virial coefficient for 4-arm and 6-arm star polymers
Sergio Caracciolo, Bortolo Matteo Mognetti, Andrea Pelissetto
We discuss the computation of the third virial coefficient in polymer systems, focusing on an additional contribution absent in the case of monoatomic fluids. We determine the inte…
Efficient prediction of thermodynamic properties of quadrupolar fluids from simulation of a coarse-grained model: The case of carbon dioxide
Bortolo Matteo Mognetti, Leonid Yelash, Peter Virnau +4
Monte Carlo simulations are presented for a coarse-grained model of real quadrupolar fluids. Molecules are represented by particles interacting with Lennard-Jones forces plus the t…
Two-parameter model predictions and theta-point crossover for linear-polymer solutions
Sergio Caracciolo, Bortolo Matteo Mognetti, Andrea Pelissetto
We consider the first few virial coefficients of the osmotic pressure, the radius of gyration, the hydrodynamic radius, and the end-to-end distance for a monodisperse polymer solut…
Infra-red divergences in the large-N expansion
Bortolo Matteo Mognetti
We investigate a vectorial O(N) model with a generic nearest-neighbor interaction W(\bsigma_i\cdot \bsigma_j) (depending on {\cal N} tunable parameters), a Yukawa (and Gross Neveu)…
Large-N_f behavior of the Yukawa model: analytic results
Sergio Caracciolo, Bortolo Matteo Mognetti, Andrea Pelissetto
We investigate the Yukawa model in which fermions are coupled with a scalar field through a Yukawa interaction. The phase diagram is rather well understood. If the fermio…
