Is gelation a singularity or a flow induced instability?
Manuel Dedola, Ludovico Cademartiri
Gelation in the Smoluchowski coagulation equation is commonly interpreted as a finite-time singularity marked by mass loss or moment divergence. We instead characterize gelation as…
Pseudoperiodic Spherical Boundary Conditions: Efficient And Isotropic 3D Particle Simulations Without Lattice Artifacts
Manuel Dedola, Ludovico Cademartiri
Periodic Boundary Conditions (PBC) introduce well-known lattice artifacts. We present a novel Pseudoperiodic Spherical Boundary Condition (SBC) that is perfectly isotropic. Through…
Modeling Brownian Motion as a Timelapse of the Physical, Persistent, Trajectory
Ludovico Cademartiri
While it is very common to model diffusion as a random walk by assuming memorylessness of the trajectory and diffusive step lengths, these assumptions can lead to significant error…
On The Effect Of Size On The Kinetics Of Reactions In Solutions
Manuel Dedola, Gaia Cassarà -Airoldi, Ludovico Cademartiri
Reactions in solution require "contact" between the reagents. We can predict the rate at which reagents come into "contact" (at least in dilute conditions), but if the initial coll…
