Theory of associating polymers with annealed and quenched sticker disorder: Mean-field solution and phase behavior
Sofia Moschin, Achille Giacometti, Amos Maritan +1
We develop a density-functional theory for solutions of associating polymers where attractions among charged monomers (stickers) are represented by local binary degrees of freedom,…
Space-filling discrete helices
Jayanth R. Banavar, Achille Giacometti, Trinh X. Hoang +2
Proteins are linear chain molecules that play a central role in life and health. Protein native state folds are modular assemblies of space-filling building blocks of α-helices, \…
Entropy of self-avoiding branching polymers: mean field theory and Monte Carlo simulations
Davide Marcato, Achille Giacometti, Amos Maritan +1
We study the statistics of branching polymers with excluded-volume interactions, by modeling them as single self-avoiding trees on a generic regular periodic lattice with coordinat…
A new mathematical model for brain memory working. Optimal control behavior for Hopfield networks
Franco Cardin, Alberto Lovison, Amos Maritan +1
Recent works have highlighted the need for a new dynamical paradigm in the modeling of brain function and evolution. Specifically, these models should incorporate non-constant and…
Theory of polymers in binary solvent solutions: mean-field free energy and phase behavior
Davide Marcato, Achille Giacometti, Amos Maritan +1
We present a lattice model for polymer solutions, explicitly incorporating interactions with a bath of solvent and cosolvent molecules. By exploiting the well-known analogy between…
