Shape spectra of elastic shells with surface-adsorbed semiflexible polymers
Hadiya Abdul Hameed, Jaroslaw Paturej, Aykut Erbas
The shape of biological shells, such as cell nuclei, membranes, and vesicles, often deviates from a perfect sphere due to an interplay of complex interactions with a myriad of mole…
Contraction response of a polyelectrolyte hydrogel under spatially nonuniform electric fields
Ekrem Bahceci, Aykut Erbas
One of the major challenges in contemporary materials science is to build synthetic structures that can mimic responsive biological tissues, such as artificial skins and muscles. P…
Structural properties of cyclic polyelectrolytes in dilute good solvent
Andrzej Grzyb, Khristine Haydukivska, Jarosław S. Kłos +2
Cyclic polymers display unique physical behaviors in comparison to their linear counterparts. Theoretical, computational and experimental studies have revealed that some of their d…
Receptor-ligand rebinding kinetics in confinement
Aykut Erbas, Monica Olvera de la Cruz, John F. Marko
Rebinding kinetics of molecular ligands plays a critical role in biomachinery, from regulatory networks to protein transcription, and is also a key factor for designing drugs and h…
Effects of electrostatic interactions on ligand dissociation kinetics
Aykut Erbas, Monica Olvera de la Cruz, John F. Marko
We study unbinding of multivalent cationic ligands from oppositely charged polymeric binding sites sparsely grafted on a flat neutral substrate. Our molecular dynamics (MD) simulat…
Friction between Ring Polymer Brushes
A. Erbas, J. Paturej
Friction between ring-polymer brushes at melt densities sliding past each other are studied using extensive course-grained molecular dynamics simulations and scaling arguments, and…
Detachment of semiflexible polymer chains from a substrate - a Molecular Dynamics investigation
J. Paturej, A. Erbas, A. Milchev +1
Using Molecular Dynamics simulations, we study the force-induced detachment of a coarse-grained model polymer chain from an adhesive substrate. One of the chain ends is thereby pul…
Phase Diagrams and Crossover in Spatially Anisotropic d=3 Ising, XY Magnetic and Percolation Systems: Exact Renormalization-Group Solutions of Hierarchical Models
A. Erbas, A. Tuncer, B. Yucesoy +1
Hierarchical lattices that constitute spatially anisotropic systems are introduced. These lattices provide exact solutions for hierarchical models and, simultaneously, approximate…
