Self-Healing Small-Scale Swimmers
Emil Karshalev, Cristian Silva-Lopez, Kyle Chan +6
Herein, self-healing small-scale swimmers capable of autonomous propulsion and on-the-fly structural recovery are described. The new strategy instantaneously restores the functiona…
Triangular Ising antiferromagnet through a fermionic lens, part 2: information-theoretic aspects of zero-temperature states on cylinders
Amir Nourhani, Vincent H. Crespi, Paul E. Lammert
A classical lattice spin model wrapped on a cylinder is profitably viewed as a chain of rings of spins. From that perspective, mutual information between ring configurations plays…
Extrapolation theory for Stokes flow past a deformed sphere
Amir Nourhani, Paul E. Lammert
We formulate a method for computing Stokes flow past a highly deformed sphere with arbitrarily defined surface velocity. The fundamental ingredient is an explicit extrapolation ope…
Efficacy of self-phoretic colloids and microswimmers
Amir Nourhani, Paul E. Lammert
Within a unified formulation, encompassing self-electrophoresis, self-diffusiophoresis, and self-thermophoresis, we provide a simple integral kernel transforming the relevant surfa…
