    Interacting Growth Walk on a honeycomb lattice

    Full text link
    The Interacting Growth Walk (IGW) is a kinetic algorithm proposed recently for generating long, compact, self avoiding walks. The growth process in IGW is tuned by the so called growth temperature T=1/(kBβ)T' = 1/(k_B \beta '). On a square lattice and at T=0T' = 0, IGW is attrition free and hence grows indefinitely. In this paper we consider IGW on a honeycomb lattice. We take contact energy, see text, as ϵ=ϵ=1\epsilon=-|\epsilon|=-1. We show that IGW at β=\beta' =\infty (T=0T'=0) is identical to Interacting Self Avoiding Walk (ISAW) at β=ln4\beta=\ln 4 (kBT=1/ln4=0.7213k_B T = 1/\ln 4=0.7213). Also IGW at β=0\beta ' = 0 (T=T' = \infty) corresponds to ISAW at β=ln2\beta = \ln 2 (kBT=1/ln2=1.4427k_B T= 1/ln 2 = 1.4427). For other temperatures we need to introduce a statistical weight factor to a walk of the IGW ensemble to make correspondence with the ISAW ensemble.Comment: 3 pages, 1 figure, REVTEX fil

    C\mathcal {C}-IBI: Targeting cumulative coordination within an iterative protocol to derive coarse-grained models of (multi-component) complex fluids

    We present a coarse-graining strategy that we test for aqueous mixtures. The method uses pair-wise cumulative coordination as a target function within an iterative Boltzmann inversion (IBI) like protocol. We name this method coordination iterative Boltzmann inversion (C\mathcal {C}-IBI). While the underlying coarse-grained model is still structure based and, thus, preserves pair-wise solution structure, our method also reproduces solvation thermodynamics of binary and/or ternary mixtures. Additionally, we observe much faster convergence within C\mathcal {C}-IBI compared to IBI. To validate the robustness, we apply C\mathcal {C}-IBI to study test cases of solvation thermodynamics of aqueous urea and a triglycine solvation in aqueous urea

    UIDB/00417/2020 UIDP/00417/2020Within the RoGeMoPorTur project, a specifc approach was adopted to analyse the importance of the peristyle not only as a central element of communication and link between the diferent architectural components of the villa, but also as an expression of a vision very specifc to its owner as a member of a Roman or Romanised elite: The peristyle, as the entrance to the villa from outside, was at the same time the frst recipient of its cultural message and socio-economic power. This study aims at a typologisation of the spatial dialogue chosen by the landowner for the introduction to that message through the pavement decoration of the peristylepublishersversionpublishe
