Equilibrium fluctuations of a quasi-spherical vesicle: role of the membrane dissipation
Petia M. Vlahovska, Rony Granek
We theoretically investigate the thermally-driven curvature and lipid density fluctuations of a quasi-spherical vesicle, accounting for the dissipation due to monolayer viscosity a…
Non-equilibrium dynamics of disordered fractal spring network with active forces
Debjyoti Majumdar, Sadhana Singh, Rony Granek
We investigate the non-equilibrium dynamics of active bead-spring critical percolation clusters under the action of monopolar and dipolar forces. Previously, Langevin dynamics simu…
Active fractal networks with stochastic force monopoles and force dipoles: Application to subdiffusion of chromosomal loci
Sadhana Singh, Rony Granek
Motivated by the well-known fractal packing of chromatin, we study the Rouse-type dynamics of elastic fractal networks with embedded, stochastically driven, active force monopoles…
Curvature fluctuations of fluid vesicles reveal hydrodynamic dissipation within the bilayer
Hammad A. Faizi, Rony Granek, Petia M. Vlahovska
The biological function of membranes is closely related to their softness, which is often studied through the membranes' thermally-driven fluctuations. The analysis commonly assume…
Kinetics of actin networks formation measured by time resolved particle-tracking microrheology
Maayan Levin, Raya Sorkin, David Pine +3
Actin is one of the most studied cytoskeleton proteins showing a very rich span of structures. It can self-assemble actively into dynamical structures that govern the mechanical pr…
Comment on: "Dynamics of Phospholipid Membranes beyond Thermal Undulations"
Rony Granek
I introduce an alternative interpretation for the short-time anomalous diffusion observed by Gupta et al. using neutron spin echo. The interpretation involves the Brochard-Lennon "…
Membrane undulations in a structured fluid: Universal dynamics at intermediate length and time scales
Rony Granek, Haim Diamant
The dynamics of membrane undulations inside a viscous solvent is governed by distinctive, anomalous, power laws. Inside a viscoelastic continuous medium these universal behaviors a…
Sufficient minimal model for DNA denaturation: Integration of harmonic scalar elasticity and bond energies
Amit Raj Singh, Rony Granek
We study DNA denaturation by integrating elasticity -- as described by the Gaussian network model -- with bond binding energies, distinguishing between different base-pair and stac…
