Conformational properties of active semiflexible polymers

T Eisenstecken, G Gompper, RG Winkler - Polymers, 2016 - mdpi.com
The conformational properties of flexible and semiflexible polymers exposed to active noise
are studied theoretically. The noise may originate from the interaction of the polymer with …

Role of temperature in the decohesion of an elastic chain tethered to a substrate by onsite breakable links

We analyze the role of temperature in the rate-independent cohesion and decohesion
behavior of an elastic film, mimicked by a one-dimensional mass-spring chain, grounded to …

Thermal control of nucleation and propagation transition stresses in discrete lattices with non-local interactions and non-convex energy

A Cannizzo, L Bellino, G Florio, G Puglisi… - The European Physical …, 2022 - Springer
Non-local and non-convex energies represent fundamental interacting effects regulating the
complex behavior of many systems in biophysics and materials science. We study one …

Temperature controlled decohesion regimes of an elastic chain adhering to a fixed substrate by softening and breakable bonds

A Cannizzo, G Florio, G Puglisi… - Journal of Physics A …, 2021 - iopscience.iop.org
We study the rate-independent decohesion process for a chain linked to a substrate through
a series of breakable elements with a softening mechanism. Such an assumption describes …

Statistical mechanical constitutive theory of polymer networks: The inextricable links between distribution, behavior, and ensemble

A fundamental theory is presented for the mechanical response of polymer networks
undergoing large deformation which seamlessly integrates statistical mechanical principles …

On the equivalence of thermodynamics ensembles for flexible polymer chains

F Manca, S Giordano, PL Palla, F Cleri - Physica A: Statistical Mechanics …, 2014 - Elsevier
Although the problem of the ensembles equivalence for flexible polymers has aroused
considerable interest, there is not an overall consensus on this topic. In this work, we present …

Thermodynamics of small systems with conformational transitions: The case of two-state freely jointed chains with extensible units

Spin variable approach for the statistical mechanics of folding and unfolding chains

S Giordano - Soft Matter, 2017 - pubs.rsc.org
The force–extension response of chains composed of bistable (or multistable) units strongly
depends on the applied boundary conditions. As a matter of fact, isotensional conditions …

Helmholtz and Gibbs ensembles, thermodynamic limit and bistability in polymer lattice models
